  1. Squirrels have planted some Pin Oak acorns in a basket of plants on my porch, which gets full morning eastern sun. I live in West Tennessee in zone 7 I believe. The little trees have grown to about 2 to 3 inches each, and have produced leaves and straight trunks (skinny trunks, but the trees seem hardy. It’s July, so when wo I transplant these into a pot for fall/winter. These porch baskets are wire with cocont bark holding the plants, with potting and garden soil from Lowes is used. Can these be Bonsai? Please advise.
