But then we had Snopocalypse. It appeared to kill my bamboo.
All the leaves were gone before the snow. And they didn't appear to come back. In a move based on "I guess it can't hurt know" method of plant care, I trimmed it way back.
Apparently, that was the right thing to do. Because over the past few weeks the bamboo sprouted new leaves. And now it is starting to fill out quite nicely.
Sometimes the best thing you can do for your plants is to do nothing. Someday that lesson might stick.
