Question
I have 4 year old black bamboo that this year appears to have gone to seed, although this is well watered it is slow to show any signs of leaf growing, although there are some, these are few and far between.

Answer
Hi Michael.. Various methods have been suggested to revive flowering bamboo. More study needs to be done with this. Some have been effective in some cases, many have not. Often when a bamboo flowers the gardener will see it decline and rip it out without any effort at reviving it, or if it is not a visible eyesore just abandon it to the forces of nature. Bamboos treated so often perish, with proper care they might be saved.
