GOOD FUNGI AND BAD INSECTS

August 21, 2014/8 Comments/in Gardening, Pests, Soil, Vegetables/by Lee Reich

Fungi I Like and Bean & Japanese Beetles (Don’t Like)

Where once scorned or appreciated only after being sautéed in butter, fungi have finally come into their own. If you’re among those who isn’t awed by fungi except when they’re sautéed, swallow this: each gram of soil (the weight of a paper clip) might house over a million fungi, or anywhere from 10 to 100 pounds of them in the top 6 inches of a 1000 square feet of soil. And most of what they do — for plants and soil, forget about your taste buds for now — is beneficial.

I recently heard of a project using fungi as a building material. On exhibit at the Metropolitan Museum of Art’s PS1 in New York City is Hy-Fi, a cylindrical tower built our of bricks made from fungi that have been fed cornstalks, the fungi’s fine, thread-like hyphae growing to create dense bricks. An organically grown building! Among the benefits touted were that a building made of fungi could be recycled.

I’m not so sure that a building that can be recycled is a good thing, but one statement by the architect did raise my hackles: that the building could be made of waste materials, such as cornstalks. The same argument could be or has been used for ethanol production, which could be made from the same waste material.

Corn stalks might be waste material in the sense that we don’t eat them, perhaps not even always feed them to animals. But corn stalks, wheat straw, and other so-called “waste materials,” as the architect perhaps inadvertently pointed out, are a gourmet delight for fungi. Also good food for bacteria (3 million to 500 million per gram of soil), actinomycetes (1 million to 20 million per gram of soil), as well as protozoa, nematodes, and other soil creatures. And don’t forget about earthworms (2 to 22 pounds per 1000 square feet of ground). There’s a lot of hungry creatures down there.

So these materials are not waste; they are food for soil life. They are what put the “organic” in organic gardening and farming. (They are “organic” in the sense that they were once living, and that they contain carbon compounds, mostly combined with hydrogen and oxygen.) They confer a range of physical, nutritional, and biological benefits to soil, plants, and, hence the animals, including humans, that feed on them. Depriving the soil of these organic materials is what led, in part, to the dust bowls of the 1930s.

Corn stalks as well as other organic materials too often considered as waste should be returned to the soil, either directly or after being first run through a compost pile. One measure of soil quality is the amount of organic material it contains.

Waiting Out Japanese Beetles

Japanese beetles have not come into their own; they have never been and continue to NOT be appreciated. The swarmed in a few weeks ago to make lace of the foliage of a whole host of plants. Grapes are among their favorites, evident by merely looking out on the landscape and picking out the hole-y grape leaves. (The leaf veins typically remain intact.) Although roses are also a reputed favorite, the beetles left mine unscathed.

Kiwi foliage made lacy by Japanese beetles

Most interesting is the beetle’s effect on my hardy kiwifruits, specifically the super-hardy sorts (Actinidia kolomikta). I have four plants, 3 females — Krupnoplodnaya, Aromatanya, and Sentayabraskaya — and one male. Of all those plants, only the Sentayabraskaya plant was attractive to the Japanese beetles, dramatically so. Looking up, I can see sky through almost every leaf.

Japanese beetles are hard to keep in check. For a few plants, hand picking into a can of soapy water (the soap so they don’t just fly out after a quick bath) is effective. The biological insecticide milky spore disease, applied to lawns to kill the grub stage in the soil, is sometimes effective, especially in more southerly locations. Of course, beetles emerging from the soil in summer can fly, so milky spore is useless unless done on a neighborhood scale. Neem is a relatively benign repellant and insecticide that’s somewhat effective sometimes; it would require too much spraying, especially for something with such an iffy effect.

So I just wait the beetles out. Plants can tolerate a certain amount of damage and the beetles typically wave goodbye to go burrow into the soil and lay eggs sometime in August. The wait was especially short this year, with most of the beetles departing by the third week in July. Thank you guys, and gals.

And Where Did Mexican Bean Beetles Go?

A Mexican bean beetle threesome

Other pests also come and go. Mexican bean beetles, mentioned last week, still are keeping to themselves, wherever that might be but not in my garden. Tomato hornworms, which are large caterpillars with voracious
appetites, stripping leaves from tomato plants in the matter of hours, turned up in a friend’s garden. Fortunately, piggybacking those beetles were what looked like grains of rice. They’re actually cocoons of a braconid wasp, which will kill the hornworm. Leaving parasitized beetles alone lets the parasite live to attack more hornworms.

Rice-like granules attached to tomato hornworm are parasites

Parasite attacks tomato hornworm; winner: parasite.

Also worth ignoring are the pimples that have been appearing on leaves of many pin oaks. Those pimples — hemispheres about 1/2” across — are galls. Plant galls are abnormal growth made in response to an irritant such as a bacteria, a fungus, or, most commonly, an insect. A few galls here and there rarely do a plant harm.

Those oak leaf galls are pocking almost all the leaves on my pin oak. Still, I’ll ignore them or admire them; they sort of liven up the look of the tree. It’s too late, anyway, to do anything about them.

WEEDS, BIRDS, & PEST-FREE CURRANTS

August 15, 2014/0 Comments/in Fruit, Gardening, Pests/by Lee Reich

I Battle Weeds and Birds, but Currants are Care-free

Part of my weedless gardening technique (which I thoroughly fleshed out in my book Weedless Gardening) involves — sad to say, for some people — weeding. After all, no garden can ever be truly weedless. Even people who spray Roundup eventually get weeds as they inadvertently “breed” for Roundup-resistant weeds, which now exist. My techniques are weed-less rather than weedless.

Which brings me to hoeing. Most years my hoe rests on its designated hook in the garage. This year, it’s hardly made it back to garage, mostly just leaning up against the garden fence alongside the gate. “And why is this?” you might ask. The answer is rain. This season, rainfall has been dropping in sufficient amounts at regular intervals, all of which has coaxed good plant growth, including that of weeds.

More importantly, the rainfall has promoted plant growth in paths and between widely spaced plants. One leg of my 4-legged “weedless gardening” stool calls for drip irrigation, which pinpoints water near plants. In a normal year, or a dry year, there’s little moisture to spur on weed growth elsewhere. This year, rainfall has democratically spurred weed growth everywhere.

Hence the hoe. The best hoes to snuff out young weeds without unduly disturbing the ground are ones with thin, sharp blades that lie parallel to the ground. All that’s needed is to slide such hoes back and forth a quarter of an inch or so beneath the surface, cutting the stems of hopeful, young interlopers. The work, if can be called that, is quick and easy, not calling for the “iron back with a hinge in it” recommended for a gardener by Charles Dudley Warner in his 19th century classic My Summer in the Garden. Too many people use a pull or draw hoe, whose blade lies perpendicular to the handle, to try to conquer weeds.

The hoes I’m recommending are so-called push or thrust hoes. Some examples include the collinear hoe, the scuffle hoe, the stirrup hoe, and, my favorite, the wingèd weeder. With any of these hoes, roots aren’t damaged and lower depths of soil remain at lower depths so that inevitable weeds seeds buried there are not awakened as they are exposed to light. (Minimal soil disturbance is another leg of my 4-legged “weedless gardening” stool.)

Still, my wingèd weeder is not effective unless it is used — frequently this season, ideally once a week or within a couple of days after a rain. Used in a timely manner, the wingèd weeder does a quick, effective, and satisfying job.

Currants are an Old-Fashioned Fruit Easy to Grow

“The currant takes the same place among fruits that the mule occupies among draught animals—being modest in its demands as to feed, shelter, and care, yet doing good service,” wrote a nineteenth-century horticulturalist. Hoeing takes time, especially this year, so it’s nice to balance that with something — currants, in this case — that is “modest in its demands.”

One of my currant bushes, a Perfection (that’s the variety name) red currant, splays its stems upward and outward in an ornamental bed in front of my house. Sharing that bed, for beauty and for good eating, are huckleberries, lowbush blueberries, and lingonberries, and, for beauty alone, mountain laurels and dwarf rhododendrons.

The only care my currant gets is, anytime from November until late March, pruning. The plant bears best on 2- and 3-year-old stems so I cut away anything older than 3 years old and reduce the number of new, 1-year-old stems to the half dozen or so most vigorous ones. The whole bed gets a sprinkling of either soybean meal (1# per hundred square feet) or alfalfa meal (3# per hundred square feet) in late fall, topped with a mulch of leaves or wood chips.

The bush began bearing towards the end of June and a few clusters of the plump, jewel-like fruits still hang from the branches. Most people use red currant for jelly or sauce. I like to eat them straight up, with my morning cereal, for instance. The flavor is tart early on but has mellowed by now.

Currants were once a more popular fruit in America, and especially here in the Hudson Valley. They are one of the few fruits that tolerate shade (and deer!), and were often grown in the shade of large, old apple trees. Local folk, including children, would ride out to the orchards in hay wagons for communal picking.

Currant is, truly, among the uncommon fruits for every garden (good book title, that).

I Reluctantly Share Some Blueberries with Birds

Just a quick note about my blueberries, which are also relatively carefree. Last year’s abundance of cicadas may have upped bird populations, or at least made birds believe that lots of food would always be in the offing. Not so, birds. Perhaps, then, that’s why so many bird are fluttering all around my blueberries, mostly on the outside of the net that encloses my Blueberry Temple of 16 plants.

Right now a hawk — a cardboard one, swooping in breezes as it hangs from a string fixed to the end of an long, inclined bamboo pole — is meant to dissuade birds from even approaching the net. Calm mornings keep the hawk still enough so an occasional bird find their way through the net (where?) to venture into the Temple.

Eerie White to Golden Flowers, with Some Fungi Helping Out

August 11, 2014/3 Comments/in Design, Gardening, Soil/by Lee Reich

White Indian pipes, mycorrhizae, and a golden flower

I do occasionally tear myself away from the farmden. So into the woods I went last Friday and as I was hiking along and glancing down at the trail, I came upon one of my favorite flowers. It’s a favorite not for its beauty but for what it hints at of goings-on beneath the soil surface.

The flower was indian pipes, Monotropa uniflora, an eerily white plant that looks like a upright tobacco pipe whose stem has been poked into the ground. Yes, it’s white. All white. You might rightly wonder how the plant synthesizes carbohydrates for energy and for structure. Photosynthesis, which makes carbohydrates, requires chlorophyll, which is green. Indian pipes don’t need chlorophyll because they get their carbohydrates from neighboring trees.

Join me while I go below ground. Stopping for a look at the roots of indian pipes, we see that they are infected with the fine threads of fungal hyphae. Now, if we follow the fine threads of the fungal hyphae out of the roots and through the soil, we eventually come to the roots of a nearby tree whose roots also are infected by one and the same fungus. A continuous connection exists from the tree to the fungus to the indian pipes.

The tree does have green leaves and, as with other plants, some of the products of its photosynthetic labors are channeled down to its its roots. Some of those products travel out the roots and into the fungal hyphae, and some of that is drawn out of the hyphae into the indian pipes for the latter’s sustenance and growth. Sounds like a one-sided relationship, a pretty good deal for the indian pipes. It is. The plant is a parasite, taking but offering nothing in return.

The relationship between the fungus and the tree, however, is symbiotic and called mycorrhizae (my-co-RYE-zay, which means fungus-root). Yes, the fungus sucks up some of the tree’s photosynthates, but in return it sucks up nutrients from the soil, then channels them back to the tree’s roots. The network of fungal hyphae in the soil is much more extensive than that of the roots, so, with fungal hyphae as “extenders,” the effective volume of soil “grazed” by roots is increased. Mycorrhizae are especially important for uptake of nutrients such as phosphorus, which roots (or their fungal extenders) must go out and find because it moves but little in the soil.

Myco . . . say what?

Wouldn’t mycorrhizae spur growth of garden plants? Yes. But look out your window; most of the plants you see are naturally mycorrhizal already. Still, deliberate inoculation might benefit young transplants. You can purchase inoculum, but the problem is that purchased inoculum often is not of fungal species best adapted to a particular location.

A better approach would be to keep your indigenous fungi happy. Limit tillage, which discombobulates the hyphae, grow a variety of plants, especially those that form mycorrhizal associations, and avoid pesticides. Also limit phosphorus fertilizers because they suppress mycorrhizae.

Another approach would be to grow your own mycorrhizal inoculant of local fungal species. Basically, you mix up a big batch of potting soil that has some indigenous soil in it and is not too high in nutrients. In this potting soil you grow a suitable host plant. (Not spinach, beets, or any plant in the cabbage family, none of which ever form mycorrhizae.) After the host plant dies at the end of the season, what’s left in the pot is indigenous fungal inoculum that can be added to a potting soil for growing seedlings. For more details, see http://rodaleinstitute.org/a-complete-how-to-on-farm-am-fungus-inoculum-production/. I use garden soil and compost in my potting mixes and assume there’s sufficient inoculum already present.

Grow Some Gold

As I rounded the bend at the back of my garden after my woodland hike, I came face to face with a flower I had planted temporarily back there, giant knapweed (Centaurea macrocephala), also known as Armenian basket flower, globe centaurea, and yellow hardhat. Plants with too many common names are usually suspect to me, and none of this plant’s names have a particularly nice ring to them — yet this plant is a showstopper.

From the whorl of rather coarse leaves at the base of the plant rises a sturdy flower stalk. At almost 4 feet high, a big fat bud forms atop the stalk, a bud that looks like a globe artichoke that has been gilded. Nice enough even then, but a couple of weeks later — which is now — a bottlebrush of lemon yellow petals spills forth from the top of the bud.

Globe centaurea, the name most euphonious to my ears, tolerates heat and cold (USDA Hardiness Zones 3 to 8), and is relatively carefree. No need to prop the flower stalk up with a stake. The blossoms put on their show for about a month, not counting the gilded opening act, and hold up well as cut flowers, or can be dried.

Globe centaurea deserves more attention over much of the country, except perhaps in the Pacific Northwest, where it’s considered invasive. I grew it years ago, and it disappeared. Nice to have it back.

Plagues Come & Go, With Some Help, and Seattle-time

August 1, 2014/10 Comments/in Fruit, Gardening, Pests/by Lee Reich

Meet me in St. L . . . Seattle

Come hear me lecture on August 10, 2014 on “Luscious Landscaping, with Fruiting Trees, Shrubs, and Vines” at 1 pm in the Garden Room at Magnuson Park. For more information, go to http://www.brownpapertickets.com/event/755459.

Plague again; keep calm

Every year it seems some new plague is ready to attack plants. A few years ago, late blight of tomato moved to the fore. Emerald ash borer, threatening ash trees, was first found on our shores in 2002. (Figuratively; literally, the insect, native to Asia, was first noted in Michigan.) What’s next?

Perhaps a calmer outlook is called for. A decade or so garlic mustard seemed ready to take over our world. Not so, now, perhaps because it’s being crowded out by Japanese stilt grass, which itself seems now ready to take over our world. Garlic mustard is native over much of the northern hemisphere, except North America, and was introduced here around 1860 as a culinary herb. As for stilt grass, it hitchhiked here from China about a century ago, as packing material for porcelain. It’s deer-resistant, for what that’s worth.

Plant problems come and go. The best approach is to keep calm and, in some cases, plant something different, something plague resistant.

Bean Beetle Management

Green beans are a mainstay of my garden, of just about every garden. More than 20 years ago, Mexican bean beetles (a species of ladybug!) found my bean plants and have plagued them every year since.

The adults, with eight black spots over a red or yellow background, wake up late from winter sleep to lay eggs on bean leaves. I’ve come to despise the yellow, balled up spiny larvae that gorge on leaves and other plant parts.

Still, I have managed to grow good crops of beans over the years, not by killing the beetles or their larvae, but by growing a different plant. Sort of. Rather than grow pole beans, which reside in the garden all season long to provide a constant source of beetle food, I have been planting successive crops of bush beans. Bush bean plants tend to bear quickly and for about 3 weeks, then peter out, so a new planting in a new bed goes into the ground every 3 weeks from mid-May until late July.

Yield from a planting tapers off just as its resident beetle population is beginning a feeding frenzy. Then it’s time to pull up the plants, thoroughly clear the bed of leaves and old pods, and rush it all to the compost pile. Chopping the debris with a machete and burying it beneath straw and manure, and watering the pile, as needed, sends the temperature soaring, killing most of the beetles. Bean beetles are good fliers, so cooking the beetles in the compost pile doesn’t solve the problem, just keeps it under control.

Death to the beetles, with restraint

Something strange happened this year: As of this writing, only one beetle larvae has been seen. Last year I doused the bean plants a few times with one of two organic sprays, which gave good beetle control. It also gave me the confidence to try growing pole beans, as I did in my pre-Mexican bean beetle days. They got some bean beetles but we did harvest pole beans.

The sprays were Entrust and Azamax, both approved for organic agriculture. The active ingredient in Entrust is spinosad, a compound found in bacteria, Saccharopolyspora spinosa, that was isolated from soil collected inside an old rum still in the Virgin Islands. Although toxic to a range of insects, it is otherwise relatively benign. Still, the label requires waiting at least 3 days to harvest after spraying.

Azamax is an extract of the seed of the tropical neem tree, native to the Indian subcontinent. In that part of the world, this one tree has been used as human food, insect repellant, bird repellant, and an ingredient of soap. It degrades rapidly in soil or in water, and is harmless to earthworms, honeybees, and insect predators. Food crops can be harvested right after spraying Azamax.

Still, Azamax and Entrust are pesticides. Perhaps the bean beetle cycle has been broken here and sprays can be forgone in the future. I’ll keep calm. No sprays this year, yet.

SWD, go away

The same two organic sprays might be called upon for another pest, the spotted wing drosophila, unaffectionately known as SWD. Also an Asian import, this one has moved east since being first spotted in 2008 in California. It is hard to keep calm with this pest because it attacks blueberries, my favorite and heretofore my most reliable and abundant fruit crop. The pest is also fond of blackberries, raspberries, and — not that it matters to you or me, because we don’t eat them — honeysuckle berries.

Again, there are management options. Because SWD seems to blow in from more southerly locations, a fine net could exclude them. Prompt refrigeration of harvested berries for 3 days kills larvae within. Thorough harvest of sound and unsound berries also keeps populations in check.

And then there’s Entrust and Azamax (or some other neem product), any of which I consider a last resort. I’m setting up traps to monitor if and when SWD arrives. (For information on monitoring, see http://www.fruit.cornell.edu/spottedwing/monitoring.html.) Till then, and after, I’ll try to remain calm. Om. Om. Ah-oh-om.

Farmden Health Club & Basil

July 25, 2014/1 Comment/in Gardening, Tools, Vegetables/by Lee Reich

Rei-King, an Ancient Exercise?

Among the many benefits of gardening is the opportunity it offers for enjoyable, productive exercise in the great outdoors. And now we can add an exercise called rei-king to boot camp, pilates, zumba, kick boxing, cardiofunk, and other ways modern humans build and maintain sleek, fit bodies. Or so I told my wife, Deb.

Rei-King by Deborah as Sammy looks on.

As with some of those other exercise routines, equipment is needed, simple equipment in the case of rei-king. Basically, the equipment is a pole, perpendicular to and at the end of which is a length of wood or metal, attached in its middle to the pole. From the lower side of the length of wood or metal are teeth, each a couple of inches apart and a couple of inches long.

Now for the exercise. You lift the pole just enough to bring the head off the ground, reach forward, and pull it towards you. For balanced exercise, it’s advised to occasionally switch which arm is most forward.

Resistance is the way to build up muscle and endurance. That resistance comes in the form of friction from material lying on the ground. This time of year, that material might conveniently be mown long grass or hay.

And Sie-Thing

I sometimes practice rei-king; more often I choose another exercise that complements Deb’s rei-king. I practice sie-thing (pronounced “sigh-thing”).

Like rei-king, sie-thing entails using one piece of equipment, a sie. The sie also has a single pole, in this case with two handles attached, one at the upper end and one about halfway down. A metal weight is attached at the bottom of the sie. The metal is a couple of feet long, curved, and sharpened on its inside edge. Muscle tone and strength is created by putting the left hand on the upper handle, the right hand on the lower handle, flexing the spine to the right and then unwinding it to the left while trailing the metal weight just above ground level.

Here I practice the ancient art of Sie-Thing.

Again, sei-thing can be made more rigorous, in this case by passing the sharp metal through tall grass or meadow plants. The taller the plants, the denser the plants, and the older plants, the more the resistance.

A side benefit of all this sie-thing is that grass or meadow plants get mown during the exercise. The fallen material drops right in place, providing an opportunity — for me or, more usually, Deb — to then practice rei-king.

By the way, either exercise is most enjoyable early in the morning. At that time, plants are turgid so the sharpened metal of the sie pops plant cells as it is drawn along. And the fallen plants, best for rei-king after lying on the ground a day or two to wilt, cling together nicely when heavy with dew. The cool morning air is also conducive to exercise.

Basil for Winter?

Many years ago I grew the few varieties of basil that were available and then wrote about them. My conclusion, at the time, was that taste differences between the varieties were minor, so the choice of what to grow should perhaps be on the fun of saying their names, which put Genova Profumatissima, Syracusa, and Fino Verde Compatto at the top of the list. What fun to wave my arms and speak their names!

Or, a variety could be chosen for the size or color of its leaf, whether for decoration or culinary use. “Spicy Globe basil, planted close together, makes soft, green mounds resembling a miniature boxwood hedge,” I wrote. Now we have yet another decorative form: Bonsai Basil.

To create a bonsai basil, a variety such as Spicy Globe — perfect, with its diminutive, closely spaced leaves — is grafted onto a special rootstock. That rootstock is another variety of basil, one chosen, in perfect world, to impart to the grafted plant vigor, disease resistance, and hardiness. Periodically shearing such a plant keeps up appearances even as it provides basil for flavoring. Over time, the trunk even turn woody.

Even better, carry on the fun and the flavor through winter. Basil is perennial in the tropics but generally does not fare well in the cool, dry air, and relatively dark conditions of a northern home in winter. All of which calls out for a vigorous, disease-resistant, hardy plant. A grafted basil. Grafted basil, even more than grafted tomatoes, are very much the new kid on the (grafted) block.

A few weeks ago I was given a couple of grafted bonsai basil plants and I’m planning to grow them as perennials. It turns out that my plants are on a rootstock called Nufar which is resistant to fusarium disease. My soil doesn’t harbor basil fusarium disease, so that rootstock is of no benefit in that department. Perhaps it will help get the plant through the long, dark winter indoors anyway.

New rootstocks that could impart vigor and hardiness to help get a bonsai basil through winter — indoors, of course, around here — are on the horizon.

————————————————-

Ah, fusarium. Reminds me of last week’s patting myself on my back about my conquest of pea fusarium, which has plagued me for years. Well, between last week and this week, fusarium has again reared its ugly head and the vines have yellowed. I did get a decent crop, however. Looks like management rather than conquest will be the key to annual harvests of peas.

Peas Please Me

July 18, 2014/1 Comment/in Soil, Vegetables/by Lee Reich

In some gardening circles, a gardener’s worth is measured by how well he or she grows peas: how soon the first pea gets to the table, the crop’s abundance, and, of course, the flavor. Sad to say, I haven’t been able to grow peas well for about 10 years.

Peas require a humus-y, moisture retentive soil and early planting, all of which I provide. But about 10 years ago, just as the crop was coming on strong, vines began to turn yellow, leaves would flag, and plants would die. The probable cause was fusarium wilt disease (caused by Fusarium oxysporum). This soil-borne fungus invades plant roots and then clogs up the vascular system.

(You may have heard of fusarium wilt of tomatoes and other vegetables. Fear not spread of fusarium among these vegetables, because different vegetables have their own fusarium subspecies. Cucumbers have F. oxysporum f.sp. cucumerinum, canteloupes have F. oxysporum f.sp. cubense, and peas have F. oxysporum f.sp. pisi. How cozy.)

Fusarium wilt probably never made it past my garden gate. It was probably already in my soil at some low level. Over the years, I’m guessing that it built up to a critical mass and was inadvertently spread — by me — on trowels, boots, and tellising. Which leads to one way to keep the disease in check: Clean trowels before planting peas; clean hoes before hoeing peas; and clean or torch the chicken wire trellises and metal support posts that keep the vines off the ground.

Some pea varieties are resistant to fusarium disease. But there are a few races of the disease. A variety resistant to one race may be susceptible to another race. Planting a resistant variety one year did not ratchet up my “good gardener rating.” The plants succumbed to the disease as in other years, and understandably so since I did not know which fusarium race I was up against, and variety descriptions for wilt resistant peas don’t always specify to which wilt race the variety is resistant.

Fusarium conquered(?)

This year I’m back in the game again with peas — and an excellent harvest it is: abundant, early, and flavorful! (These are shelling peas, which take longer to mature than snap peas or snow peas, but also taste better even if they do need shelling.)

One thing that I did this spring — the thing that I’m touting as responsible for my good crop — was to plant the pea seeds in my south vegetable garden, where I haven’t grown peas for the past 6 years. My wan efforts over the years have been plantings in my north vegetable garden, and they have been consistent failures.

F. oxysporum f.sp. pisi survives from year to year in the soil as spores, very hardy spores. So hardy that the recommendation is frequently made not plant peas again, ever again, in tainted soil. Other recommendations are to wait 5 or 10 years before replanting. In either case, of course, it’s necessary to be very careful about spreading the disease again on tools, boots, or trellises.

And again, the ideal would be to plant disease resistant varieties.

Good rotations

People sometimes ask me if I rotate my crops each year. Crop rotation does not involve twirling plants; it’s moving certain plants — be they in a botanical family or part eaten — to different parts of the garden each year.

Sammy, the pup, guarding garden beds

In the case of plant families, it’s a way to reduce pest problems because family members may host the same pest (clubroot disease of broccoli, cabbage, turnips, and radishes, for example). A pest that overwinters in the ground will eventually starve if a suitable host is not on hand on which to feed. A pest that flies or that shoots spores far and wide can travel some distance to find a host, but that, fortunately, is beyond the capacity of many pests.

In the case of rotating by part eaten, such as leaf, fruit, or root, the idea is to balance nutrient uptake. Leafy vegetables are hungry for nitrogen, root vegetables for potassium, and fruiting vegetables for phosphorus.

It’s generally safe to rotate vegetables on a three year cycle. That is, not to return a vegetable in the same family or with the same part eaten to the same place sooner than within 3 years. Planting in beds makes this easy because once the garden is planned out, you just move the crop to the next bed, or two beds away for further distance, each year.

Do I rotate my crops? You betcha’. With peas, I’ll try the 3 year rotation in the south vegetable garden. And I’ll wait at least another 5 years before planting them again in the north vegetable garden, then giving the south garden a “rest” from them. It’s good to again be unzipping green pods and scooping out the sweet peas within.

Serendipity Strikes!! & Join Me in Seattle

July 16, 2014/2 Comments/in Design, Tools/by Lee Reich

Join me in Seattle on August 10, 2014 for a talk I’ll be giving on “Luscious Landscaping — With Fruiting Trees, Shrubs, and Vines!”. Luscious landscaping is the way to beautify your yard and, at the same time, to put (very) local, healthful, flavorful food on the table. Following the lecture, we will explore the gardens at Magnuson Park. For more information about this event, go to http://leereich.brownpapertickets.com.

Ice Cream for Poppies

I first learned the word “serendipity” when I was in junior high school; it was the clever name of an ice cream shop that my parents had come upon in New York City. I’ve been on the lookout for it ever since: the word, not the shop. And I find it, occasionally, in the garden.

Like yesterday, for instance. Last March I sprinkled corn poppy (Papaver rhoeas) seeds on a flower bed that’s also home to espaliered Asian pears and a plum tree. Looking down at the dust-like seeds in the palm of my hand, it would have been hard to imagine that they could ever amount to anything. Especially since I did nothing more than sprinkle them on top of the ground, the whole packet.

But the seeds did amount to something, to more than just something, to oodles and oodles of two-foot-long stems capped by orangish red blossoms. The color is similar to that of Oriental poppies (P. orientale), but corn poppy flowers are smaller and more delicate, “all silk and flame,” to quote John Ruskin. Not exactly a serendipitous planting because I did, after all, sow the seeds. But I could hardly have predicted the exuberant response.

In amongst other plants, the flowers are held high. At the front edge of the bed, though, the dainty heads flop down on the lawn. Which would be okay, except that it would be a shame to mow those silky blossoms when mowing the lawn at the bed’s edge. Likewise, it would be a shame to let the grass grow unfettered up around and hiding the blossoms. Too messy.

So yesterday I propped the floppy plants up with a fence. Nothing fancy or permanent, just five short bamboo canes pushed into the ground about eight feet apart as posts. The crosspieces, four long bamboo canes each slid along the lawn beneath the flowers, were then lifted and lashed to the short canes a foot above the ground.

Serendipity. Not only are the flowers up off the ground but the bamboo “fence,” simple as it is, greatly improved the appearance of the bed, visually defining it to better highlight the plants.

Tea Crabs into a Tea Hedge, with a Doorway

My most serendipitous planting was many, many years ago, of tea crabapples (Malus hupehensis). I was using these plants for research when I was working for Cornell University. I needed clones, and tea crabapple has the quirk of apomixis, which means that its seeds do not reflect the sexual union of pollen with egg cells; the seeds are formed only from mother tissue so grow into clones of each other and the mother plant.

Privet hedge melding into tea crabapple hedge

Starting many tea crabapples from seed left me with extra plants, so I took eight home and planted them in a tight row, with only a couple of feet between plants, along and about five feet from the back edge of my garage/barn. What was I thinking? Tea crabapple can grow 40 feet high and wide!

As the plants grew, I sheared them into a hedge 10 feet high and 4 feet wide. After a few years, I put a rear, sliding door on the back of the garage/barn. Rather than walk out that door into a tree, I cut out one of the crabapples, and sheared a living doorway through the row of remaining trees.

I subsequently planted a privet hedge that runs perpendicular to the north edge of the crabapple hedge. Because the privet hedge is only about 3-feet-high, I decided to meld it with the crabapple hedge by letting it swoop upwards at their meeting. Access was needed through the privet hedge also, so another arch was created, this one higher and wider to let my tractor pass through.

It’s all very playful and, to me, pretty. And it all started with a mindless planting of extra tea crabapples.

Shearing Easily

The height and length of these hedges present maintenance challenges. Years ago, scissoring hedge shears made the work pleasant but very slow. The top of the crab hedge demanded my climbing a ladder and swinging a shearing knife — a dangerous proposition.

Shearing my tall hedge with Black & Decker pole pruner

Black & Decker pole pruner makes me taller

Technology has come to the rescue. Nowadays both hedges are kept trim and neat with two tools, both powered by 20 volt lithium batteries. What I can reach gets clipped with a Black & Decker battery powered hedge trimmer. Thanks to my Black & Decker battery powered pole hedge trimmer, the 10-foot-high hedge no longer demands a ladder. The trimmer’s articulating head makes it easy to give the upper sides a 45 degree cut and then, after repositioning the blades at 90 degrees, to make a flat cut along the top of the hedge.

The pole trimmer is especially important for making it convenient to cut high up on a hedge, the part most likely to be neglected especially on tall hedges. Hormones within every plant favor most vigorous growth highest up in the plant. So the top of the hedge, left to its own devices, would naturally overgrow the lower portions, leading to shading and bare branches lower down. Keeping the upper part of the hedge narrower than the bottom counteracts this tendency.

Earliglo strawberries are on the wane. Time to move on to other fruits, still strawberries but very different strawberries in all respect. Alpine strawberries. The largest of them are the size of a nickel but each packs the flavor of a silver-dollar sized berry.

Alpine strawberry is one botanical form of wood strawberry (Fragaria vesca, often referred to by the French name, fraise de bois), a different species from the familiar garden strawberry. Wood strawberries are dainty plants that grow wild along the edges of woods in Europe, North and South America, and northern Asia and Africa. This is the wild strawberry of antiquity, mentioned in the writings of Virgil, Ovid, and Pliny, the strawberry that garlanded medieval religious paintings and was later depicted in grand proportions in Bosch’s Garden of Delights (c. 1500).

‘Pineapple Crush’ white alpine strawberries

The alpine form of wood strawberry was discovered about three hundred years ago east of Grenoble in the low Alps. It soon surpassed other wood strawberries in popularity because of its fruits are larger and borne continuously throughout the growing season, and because the plants do not make runners. I’ve even coaxed them to bear fruit in small (4-inch) flowerpots.

Some alpine strawberries bear white fruits, and those are the ones I grow, for two reasons. First, the flavor, sweet and pineapple-y, is better than the red ones. And second, being white, the birds don’t notice them so I can wait to harvest until they are dead ripe and delicious. All season long.

That same leisurely harvest is not possible with another uncommon fruit that’s just starting to ripen. Gumis (Elaeagnus multiflora) have a pleasant, tart flavor with a bit of astringency. More than a bit until they are thorough ripe. The variety I planted, Sweet Scarlet (from www.onegreenworld.com) may be a tad sweeter than run-of-the-mill varieties.

The three-quarters-inch-long gumi fruits, scarlet red and speckled with silver, make a striking picture as they dangle on long stalks from the undersides of the branches. Birds also find the fruits very attractive. I’ve grown gumi for many years and last year was the only year in which I was able to harvest gumis ripe and in quantity. That was the one benefit of last summer’s invasion of cicadas, which birds evidently found more luscious than gums.

Cicadas or not, I’ll keep growing gumis. The large shrubs are able to garner nitrogen from the air, the leaves have an attractive silvery sheen that contrasts beautifully with the scarlet fruits, and the flowers perfume the air with a sweet aroma.

Perhaps the birds will leave me a few fruits to enjoy.

Read and learn more about alpine strawberries and gumis in my book Uncommon Fruits for Every Garden (2004).

Let’s segue from tongue to nose and eyes. For years I’ve grown various David Austin roses with increasing success, the increase due to Mr. Austin’s breeding increasingly better roses rather than to my increased skill as a rosarian. It’s cold here on the farmden, and cold is what usually weakened or did in the roses.

My attraction specifically for David Austin Roses lies in the full bodied bushes, their pest resistance, and — most important — the old-fashioned shapes (often rounded or cup-shaped), colors (often pastels), and fragrances of their blossoms.

‘L. D. Braithewaite’ rose

‘Strawberry Hill’ rose

Last winter was brutal for many plants, roses included. Yet the variety L. D. Braithwaite rose, planted in an unprotected location just outside the vegetable garden, weathered the cold unscathed. It is now drenched in deep red blossoms against a background of reddish leaves. The variety Charlotte didn’t fare so well. It was killed to the ground, perhaps lower; I dug it up.

The variety Strawberry Hill suffered some dieback despite protection afforded by the south-facing brick wall of my house. I’m glad I didn’t trash this bush because it’s also now covered with blossoms — flat-topped cups of pink petals that emit a sweet, almost candy-like fragrance. Delicious!

And more good scents: Catalpa. Although native to a relatively small area in the Midwest, catalpa can now be found throughout the East and as far west as Utah. And it’s spreading.

But let me first backtrack to a few years ago at the local farmers’ market. One farmer had buckets filled with white blossoms that rivalled orchids. I looked and looked at them, trying to figure out what they were, then finally asked. I was embarrassed to learn that they were catalpa blossoms, which I’ve admired for decades but always from afar and with their surrounding cloaks of large leaves.

This year I decided to cut some blossoms, strip off the leaves, and put them in a vase. And that’s when their delectable scent was fully revealed.

By the time you read this, catalpa’s will have finished blossoming. Mark your calendars for next year.

Chickens & Gooseberries, A Bad Combination

June 26, 2014/2 Comments/in Gardening/by Lee A. Reich

Chickens, Gooseberries, Rose Pruning & Asparagus

Good gardening is not religion. Balancing and rebalancing is what’s needed, not the constraints of dogma. You want to garden naturally? Dogma would dictate doing nothing, in which case you wouldn’t have a garden. You want to grow only native plants? Then forget about tomatoes, apples, and tulips. And are the plants you want to grow truly native on your “back forty,” or down the road where the soil is slightly wetter in summer?

Gooseberries and chickens are what turned my thoughts to the need for balance today. I grow over a dozen varieties of gooseberries, dessert gooseberries with flavors akin to those of grape, plum, and apricot. I also “grow” seven Bantam chickens; they provide decoration, insect control, eggs, and some degree of entertainment.

On the downside, chickens’ scratching in my garden beds in search of insects and seeds messes up what could be a very neat and orderly space. (Or, looked at in a more positive light, the chickens’ scratching adds a cottage-y blowsiness to the scene.) A four-foot-high fence surrounding the two vegetable gardens keeps out the chickens and those gardens productive. An eighteen-inch-high fence around some other garden areas was meant to, if not to definitely keep the poultry out of those areas, at least to make them do their own balancing, weighing the benefit of entering the fenced area against having to vault the fence. (Clipped wings tips the balance somewhat more in favor of not vaulting the fence, but not enough.)

A few days ago I noticed that this year’s especially good crop of gooseberries in the making were no longer in the making; most were gone. Gooseberries rarely suffer from late frost, at least here, so that could not be the reason. Gooseberries do not need cross-pollination, and, anyway, I have plenty of varieties for cross-pollination and bumblebees were buzzing all over the bushes in bloom. So pollination issues could not be the problem either.

Chicken and young, gooseberry bandits

I lay blame for the paltry crop of gooseberries squarely on the shoulders of the chickens, who have been hopping the low fence around the planting for weeks. Mostly, they seemed to be scratching the ground beneath and around the gooseberry plants but I wouldn’t put it past them to help themselves to berries also.

So, what to do? Putting a four-foot-high fence around the gooseberry beds would keep the chickens at bay but, with all the other fencing here, the scene could begin to look like a prison. The chickens could become soup. Or I could allow the chickens their indulgence.

Another balancing act: Roses, now in bloom, look great either on the plant or in a vase. For roses that bloom all season long, cutting the blossoms coaxes new ones forth. A win-win situation. Except that towards the end of the season, it’s best that plants get ready for winter by slowing down and toughening up. Letting rose blossoms remain on the plant and go on to make fruits — rose hips — helps slow them down.

A couple of weeks ago, a visitor looking at my asparagus patch commented on how nice it was that I still had asparagus to harvest. Of course asparagus was still coming on strong; it was only early June!Balance again.

<“>Asparagus is a perennial vegetable whose spring spears are fueled by energy stored over winter in the plants’ roots. For a good asparagus harvest, the goal is to balance spear harvest against the plants’ need to pack away extra energy, created by photosynthesis, in their roots.

Greenery is needed for photosynthesis. If spears are harvested all season long or even for too much of the season, roots are left with insufficient energy reserves going into winter. The result: Plants either die or push forth few, spindly spears the following spring.

So the tack is to harvest for a period in spring short enough to let plants start packing away fuel for winter and the following spring. A good balance is struck by allowing about eight weeks for harvest. After the end of June, spears emerge and then unfold into those ferny fronds which, left untouched until they turn brown in autumn, have time to create energy and store away energy in the roots for another eight weeks of harvest the following year.

With warm weather, asparagus needs to be harvest every couple of days or so. At each harvest, I cut down each and every spear, including those that are too skinny for eating or those that escaped previous harvest and have begun to unfold ferny foliage. Thorough harvest not only keeps new, fat spears emerging but also helps control asparagus beetles. These beetles feed on those early emerging spears. Cut all the spears early in the season and the beetles starve.

If you have never seen the beetles, look on the spears for small, black specks. Those are beetle eggs. Just wipe or hose them off, or go ahead and eat them with the spears. Asparagus and eggs is a classic combination — admittedly, the eggs for this combination are chicken eggs. Perhaps the chickens should stay.
