After years of reading about bonsai and gathering tools... I finally purchased 3 procumbens last weekend. Then the other night, I trimmed and potted them. I did not wire them. I was not sure about it, as branches are somewhat stiff, though I am new to this, I would not be the one to judge whether they were too stiff or not. Perhaps wiring would improve their looks. I will be working on a few maple trees I picked up last weekend as well. Bot that is a different thread.
