Our large stand of bamboo is making seed heads. We do not know the variety, had always thought is was a mix with some yellow wood and some black. We aren't sure how old this stand is, so maybe they have just completed their life cycle, or maybe the late snow storm this year stressed them? The whole stand went from lush and green, to brown in about a month. Is it likely that the stand will die after going to seed? Do we need to cut them down before the seeds mature and spread around our neighborhood? This stand is our main source of privacy from our neighbor and provides shade from the afternoon sun. Yikes! Thanks so much for any information you can provide, Debbie
