I collected two maples in early April (Zone 6A). (I suppose it would have better to collect in mid to late March.) I chopped the trunk of each tree, leaving roughly four feet. I potted them in a bonsai soil mix. Once a week I give them root hormone, a vitamin mix, and something for "transplant shock." Here's the issue. Some of the leaves - it seems the larger ones - are starting to wilt. We had some strong wind the other day, so I'm sure that didn't help. Here's what I'm wondering. Would a humidity tent help? Would a heat source underneath the trees help the roots develop faster? If need be, would it help to snip off some leaves in an attempt to let the roots catch up? I collected two other maples and a beech, and they're doing quite well. I'm not sure what's going on with the two maples in question.
