Bamboo poles

Late Autumn and early winter is the perfect time to harvest large bamboo poles for long term drying and long shelf life, as that’s when they have the least amount of water in them. I have often harvested fresh green this years crop in May, just weeks after sprouting, when they are all full of sugary water.
But for long term use, for full drying and strength without cracking, I want to harvest poles from the 3rd and 4th years. I have had several in storage now for several years and I am going through them to price them and use them in projects. Please let me know what your bamboo needs are.
