Yearly Archives: 2018

Dry, Wet, Bad, Good?

Some Bad

Wow! What a gardening year this has been. Looking back on 2018, it’s been the oddest year ever in terms of weather, insects, and disease.

After starting off the season parched, seemingly ready to go into drought, the weather in July did an about face. The rains began. Average precipitation here in the Northeast is about 4 inches per month. July ended up with about 6 inches, August saw 5 inches, September 8 inches(!), October 5 inches, and November 8 inches(!!).

All that rainfall brought humidity, which might have been responsible for my celeriac plants hardly growing, then rotting.

Celeriac, early in the growing season, before the rains

(Perhaps not, because this was my third growing season of failure with celeriac.) I’m taking this as a celeriac challenge. Perhaps next year I’ll try them in a large tub where I can have more control over soil composition and moisture.

The humidity also had …

Mystery Solved, and Frigid Dealings

Mystery Plant: No longer a Mystery

Last week I mentioned my brother’s mystery shrub, which he wanted to prune back heavily. I told him it was okay to do so even though I — and a number of experts I consulted — could not identify the plant.

(Drum roll . . .) The plant has finally been identified, by Mark Brand of the University of Connecticut, as Wilson rhododendron, Rhododendron x laetevirens. I had narrowed it down to R. carolinianum, which is one of the parents of this hybrid, the other being R. ferrigineum.

Wilson rhododendron flower bud

My brother’s not noticing flowers on this rhododendron is understandable. It’s a super cold hardy but sparse bloomer that’s grown mostly for its foliage; the pointy leaves don’t droop or curl, but remain perky, even in frigid weather.

Now I can sleep nights.

It was Cold Outside!

Talk about frigid weather: I was surprised at how cold it …

Read the Book, Bro’

To Prune or Not To Prune, That is the . . .

So I visited my brother and his family for Thanksgiving. As usual, we walked around his yard to look at his plantings. As usual, he asked my advice, this time about pruning. (As usual, he didn’t want to consult a copy of my book, The Pruning Book, which I had given him a few years ago. “Why read it, when I can just ask you?!” he says.)

He was considering taking blades to a row of handsome, evergreen shrubs along the front of his house. Over the years, the lengthening branches had sprawled out to encroach upon the bordering lawn, in some places leaving exposed bare stems. He questioned whether new growth would sprout if he lopped all those sprawling stems back to near the roots.

But what was the plant? I had an excuse, admittedly rather lame, …

Of Crocs and Glads

No-Dig Crocs

Plants grow and multiply, which sometimes causes trouble. Such trouble was highlighted this week as I was digging up my crocosmia bulbs.

Backpedaling perhaps 20 years, you would have found me ordering crocosmia bulbs from a mail-order catalog. I’d seen the plants blooming in a friend’s garden in New Jersey and marveled at the graceful flower stems that arched up and out from clumps of sword-shaped leaves. Lined up near the ends of each flower stalk were pairs of tubular, hot scarlet blossoms.

Crocosmia isn’t supposed to be cold-hardy outdoors where winter temperatures drop below minus 10 degrees F. (hardiness zone 5), so the first couple of autumns, as instructed, I dug up the bulbs for winter storage. Each spring following, the plants would get off to a slow start, finally blooming late in the season or not at all.

In disappointment or laziness, I stopped digging the bulbs up each fall. …

Of Worms and Leaves, Here and Beyond

Unreiking is Good Exercise

For the past few days I’ve been engaged in the esoteric exercise of unreiking. Basically, this involves lifting heavy (or sometimes light) sacks, slitting them with a knife, and then moving my arms back and forth over the spilled contents. Okay, okay, the “sacks” are plastic bags, their contents are autumn leaves, and I’m holding a pitchfork in my hands as I spread out the spilled leaves.

Sammy is looking forward to this leafy mattress

(Unreiking is the reverse of another esoteric exercise, reiking, whereby  . . .  well, leaves are raked up into plastic bags.)

Some people have too many leaves or otherwise don’t want them around. I have too few leaves and have use for them. By unreiking, the leaves get spread beneath my berry bushes, grape vines, and pear trees. These leaves feed bacteria, fungi, and other soil microbes, which slowly rot down the leaves to …

Greenhouse Happenings, Figs and Lettuce and . . .

Darkness Descending

Plant growth has come screeching (almost) to a halt. Lettuces just sit, hardly growing. No wonder, you are no doubt thinking. It’s getting colder and colder outside. I know that, but I’m writing about lettuces in my greenhouse. The issue isn’t lack of heat. It’s lack of light.

For more evidence that light is the issue, look to good vegetable gardens in southern Europe. In that mild climate, harvest from a well-planned vegetable garden continues year ‘round. But year ‘round harvest there takes planning — lack of light also makes for very slow growth over there in these darkest months. Unprotected plants survive because the winter weather never gets that cold over there. (And cool-season vegetables, such as spinach, radish, and turnips, that we plan for sprig or fall, are what do well in Mediterranean winters.)

My garden here in the Hudson Valley, at about the 42nd parallel, experiences winter day …

Winter Prep for Some of my Figs

Fig Abuse?

Anyone watching what I was doing to my fig trees might have called “Fig Protective Services” to have my trees removed to a new home. But figs are tough plants and tolerate a lot of what looks like abuse.

Let me offer some background: Figs are subtropical plants so can’t survive to fruit outdoors around here. I grow a few fig trees in pots that I can put in a protected location for winter (more on that later). Problem is that the trees’ roots eventually fill the pots and exhaust  nutrients in the mix.

I could move each tree to a larger pot. Then the branches could grow commensurately larger, and more growth of branches translates to more figs to harvest. But these pots have to be moved every spring and fall, and there’s a limit to how big a pot I can handle.

The other way to give the roots new …

Mo’ Plants

Cyclamen Addict

I’ll admit to being an addict. But my addiction — to propagating plants — is benign. It pains me to throw away an interesting seed or pruned-off stem; either can grow into a whole new plant, anything from a charming little flower to a towering tree.

Hardy cyclamen self-sown seedling

Hardy cyclamen in pot

Case in point are some cyclamen seeds I collected and sowed a couple of years ago. The mother plant is Cyclamen hederifolium, a species that differs from the large, potted cyclamens you now see offered in garden centers, hardware stores, even supermarkets. Cyclamen hederifolium is cold-hardy here, so comes back year after years planted outdoors in the ground, and it’s a dainty plant, with small flowers and commensurately small leaves. Otherwise it looks just about the same as the widely sold commercial species, the pink or white flowers hovering like butterflies on thin stalks above the …

Shaving and Composting

 . . . But My Garden is in Order

“Some men there are who never shave (if they are so absurd as ever to shave), except when they go abroad, and who do not take care to wear polished boots in the bosoms of their families. I like a man who shaves (next to one who doesn’t shave) to satisfy his own conscience, and not for display, and who dresses as neatly at home as he does anywhere. Such a man will be likely to put his garden in complete order before the snow comes, so that its last days shall not present a scene of melancholy ruin and decay.” So wrote Charles Dudley Warner in his wonderful little book (much more than a gardening book) My Summer in a Garden (1898). I gave up shaving a few months ago, but I am putting my garden in order for autumn.

The scene …
