New Culms are Dying
Posted: Tue Feb 07, 2017 5:11 pm
Hi, I live in Sarasota, Florida and have 5 stands of 8-10 year old bamboo, which have always been fairly healthy. I noticed issues developing recently on my blue bamboo and giant timber bamboo, especially as it related to new growth. Please see the three attached pictures.
- New Growth - a new shoot will come up and appear to be okay. But when it is about 2-3" high, it stops growing, dries out, and I can push the top off and underneath is about a 2" wide hollow culm at about ground level.
- At about 8-10' - if the new shoots make it past that point, when they get to about 8-10 feet high, they develop a strange pattern of holes in the culms. They continue to grow, but when they reach about 15', they stop and either die from the top down and flop over, or the top grows into a sort of pagoda formation and then they die.
This is occuring on ALL new growth on the blue bamboo and MOST new growth on the giant timber. My other stands are not experiencing this. Local experts do not know what is causing this. Any ideas??
