Help with stunted bamboo shoot tips
I have a punting pole (clumper) bamboo plant that has been in ground for one year now. It seems to have acclimated to the hot summers we have in Phoenix. This spring, its sprouted to shoots that reached 8-10 ft, but since then subsequent shoots will emerge sprouting 3-4 feet before the tip of the shoot browns out, then branching takes over the growth. Now that we are in fall the main shooting season, the shoots are not making past 1 ft. Other than that the secondary growth is lush and the plant seems healthy.
Any one know what kind of phenomenon is occuring?
