I have two young Japanese black pine trees that I started from seed about seven years ago. They are destined to become bonsai-like tonsai plants in pots in the coming years. I’m impressed with how hardy and flexible these plants have been–they dry out, get too wet, and both of them have fallen several times off of tall shelves in high wind.
Future plans for these trees are to start trimming and candle-ing them so they start to fill out a bit and get some character. Then, I’ll start looking for some good pots to move them into.
