I looked up into the tree that I had planted 20 years ago and saw what I had long feared: two major limbs with sparse, undersized leaves. Blight had finally got a toehold on the Colossal chestnut tree, which, for the past 15 years, has supplied us with all the chestnuts we could eat. (“Colossal” is the variety name, apt for the size of the chestnuts it produces.)My first inclination, before even identifying chestnut blight as the culprit, was to lop off the two limbs. Once I got up close and personal with the tree, the tell-tale orange areas within cracks in the bark stared me in the face.There is no cure for chestnut blight. Removing infected wood does remove a source of inoculum to limit its spread. In Europe, the disease has been limited by hypovirulence, a virus (CHV1) that attacks the blight fungus. Some success has been …
Because I’ve grown a number of varieties of blueberries for a long time, I’m often asked what variety I would recommend planting. Or whether you need to plant two varieties for cross-pollination in order to get fruit.
The answers to both questions are intertwined. First of all, blueberries are partially self-fertile so one variety will bear fruit all by itself.
But — and this is important — berries will be both more plentiful and larger if two different varieties cross-pollinate each other. (Apples, in contrast, are self-sterile so, with few exceptions, won’t bear any fruit at all without cross-pollination.)
Benefits of cross-pollination aside, why plant just one variety of blueberry? Different varieties ripen their fruits at different times during the blueberry harvest season. With a good selection of varieties, that season can be very long.
Here on the farmden, the season opens with Duke and Earliblue, both usually ready for picking …
Popcorn & Chestnuts, Bigger is Better But Not Always
Orville Redenbacker’s popcorn may be an “exclusive kernel hybrid that pops up lighter and fluffier than ordinary popcorn,” but my popcorn — nonhybrids whose seeds I’ve saved for many years — tastes better. I grow two varieties, Pink Pearl and Pennsylvania Dutch Butter Flavored Popcorn. This winter my popcorns’ poppability was especially poor, probably because of the weather. Really! Popcorn pops when the small amount of water within each kernel, heated above the boiling point, builds up enough pressure to explode the kernel, turning it inside out. For good popping, a kernel needs an intact hull and moisture within. Not just any amount of moisture, though, but as close as possible to 13.5%. (Other whole grains, such as wheat berries and rice, don’t pop with the same explosive force as popcorn because their hulls are porous.) My popcorn spends winter, …
One of the best things about no-till gardening is not having to till. The soil of my vegetable garden hasn’t been disturbed for over 2 decades. Besides avoiding the hassle of tilling, not having to till makes for quicker and easier planting.
Today, for instance, I planned to clear a bed of harvested edamame plants to make way for lettuce. Easy! I just pulled up each plant, coaxing it along, if necessary with a Hori Hori knife so that I had the tops and only the main roots in hand. Once plants were up and out, light use of a lawn rake gathered up dropped leaves, pods, and other debris, and brought what few weeds were still present into focus for removal. In 20 minutes, I had the double row of plants in a 20 foot by 3 foot wide bed cleared, and the bed cleaned up.
