The 15 oak logs sitting in the shade of my giant Norway spruce tree more than earned their keep last year. Seven of them got inoculated with plugs of shiitake mushroom spawn in the spring of 2013; eight of the were inoculated in the spring of 2014. With little further effort on my part, reasonably good flushes of mushrooms appeared through spring and summer, then heavy flushes through fall until the mild weather turned frosty. My friends Bill and Lisa, also shiitake growers, told me a few days ago how they’re still harvesting good crops, cold weather notwithstanding. They brought one of their logs indoors, where it stands in the sink of their laundry room. Great idea! I don’t have a laundry room, but I do have a cool, dark, moist basement, i.e. mushroom heaven. So a few days ago I carried one of my …
This winter’s cold is most evident on bamboo. Clumps of tawny, dead leaves, still attached to the canes, stare out from among the trunks and stems of dormant trees and shrubs. I hadn’t realized that bamboo was so widely planted. The depth of cold isn’t what killed the canes and leaves; it was the duration of cold. Seventy miles south of here, leaves of yellow groove bamboo, Phyllostachys aureosulcata, among the most cold hardy of the thick-caned bamboos, typically stay green and fresh all winter, but even they’ve been killed.
My bamboo, before pruning
No, the plants aren’t dead; just their canes and leaves. Warm weather will coax new shoots from the roots, shoots that will push skyward rapidly. I’ve measured as much as 6 inches of elongation per day. The record for bamboo growth, not around here, of course, is almost 3 feet in …
Yes, we have no bananas. We do have a banana tree.
Decades ago I was in a similar situation. How could I resist a catalog ad for a dwarf banana tree, one that wouldn’t grow more than 6 to 8 feet high, so could be accommodated within the confines of a standard room? I bought the small pup, which is what small, plantable offshoots from the mother tree are called, and planted it in a large pot. The pup grew. And grew. And grew. The plant topped out at 6 to 8 feet but the developing leaves, rolled up and pointing skyward before unrolling and flopping down, reached a lot higher. Banana isn’t really a tree; it’s a giant herb whose “trunk” is, in fact, made up of concentric layers of rolled up leaves that don’t flop down to a more horizontal position until they unroll.
Flowering is desirable in some garden plants (fruit trees, broccoli, and, of course, flowers) and undesirable in others (lettuce, cabbage, and arugula). I’m not sure how I feel about the flowers recently appearing on my bamboo (Phyllostachys aureosulcata). Yes, bamboo! Bamboo typically flowers only after decades of growth, sometimes after more than a hundred years of growth. My bamboo is about 25 years old.
The downside to bamboo flowering is that it weakens, sometimes even kills, the plant. And “the plant” could be a whole grove since bamboo spreads by rhizomes (underground runners). All shoots are connected underground and are, essentially, one and the same plant. Bamboos sometimes flower gregariously, that is,
most or all of them all over the world flower in unison, so death or weakening could be more widespread than my little grove.
