Hello everyone. I planted about 30 bamboo plants in April 2012. They were a wild from southeast Pa. The bamboo that I picked from were about 30 feet tall 2.5 inch in diameter. I dug up and replanted approx. 30 plants with roots. They have spread throughout the summer but are very tiny. (2 feet high) what should I expect for this next growing season which is only a couple of months away? I'm hoping for as much growth as possible. Please help.
