There's a large clump of bamboo in the vacant lot next door that I've admired for the last couple of years. A month ago it looked like it was dead. With our month long rains it suddenly sprang back to life, all the brown turned green and a few side shoots were popping out.
I've been warned about bamboo that "runs" rather than staying around a central clump. This bamboo has not moved from it's center more than a couple of feet in four years. A few of the new sprouts were relatively easy to separate with what looked to me like a good root ball. We'll see and I actually have three started to cover losses.
