Phyllostachys Growth Rate in Zone 7
Hello. I am new to the forum and hope that I am starting a new thread properly. I have fallen head over heels for running bamboo, mainly timbers. I live on some acreage and have planted about 16 new running bamboo plantings in various areas, mainly on or near my perimeter. I was hoping to hear from someone with experience growing in my zone, 7 so that I can have an idea of growth rate or more specifically what size each stand may achieve in say 3-5 years. I have planted healthy divisions with good sun, amended soil, and heavy mulching from composted horse manure. I haven't put in rhizome barriers and after endless research have decided that I can easily contain it by staying on top of mowing and removal of culms in areas I don't want it in, which candidly isn't many places. I am fairly confident that my problem will not be containment but rather not growing fast enough for my liking. I hope to have some nice groves and have planted P. Vivax (gold and green both), madake, black bamboo, and megurochiku mainly. Each new planting has about 2-4 culms at present and this is their first season in the ground. Would love to hear from anyone with experience about spread rate etc. and what to expect possibly. Thanks so much in advance! I love reading these forums and am glad to have joined. All the best.
