When did you collect it? I love larch but have minimal experience with them, but I do know they need to have recovered from the trauma of collection before meaningful work can be done to them. It definitely has potential, so you want to make it's health your primary focus for now.Really like the bark on this Larch I collected this fall from a bog. Also made a drawing of where I hope to take it. Think I can do it in 3-5 years?
So, you collected it in the last 3 weeks or so? I'd say waiting a year or two is a good idea. I love Nick's book, by the way.Dav4 I collected it this fall, not planning to touch it for 1-2 years or until it's ready. I have other Larch to play with in the meantime. I know people always recommend collecting these in the spring but I have had good success collecting larch in the fall. Plus Nick Lenz recommends it in his book Bonsai from the Wild. I did save some better trees at this spot to collect next spring.
Mr. Lenz is the man, probably my favorite book. Yes I collected it almost exactly 3 weeks ago.
I would not put it on a heating pad. They are native to your area, cold temperatures are not a problem. I would protect it from winter sun, and wind. A heating pad, even set at 40 F would run the risk of drying the tree out. And keeping the roots too warm to go dormant. Bury it in snow and forget it until the snow melts. What does Nick's book say about wintering fall collected larch? Go with Nick's suggestion.
Minus 20 for weeks on end?areas with cold temperatures too.
Pinch those shoots before they develop terminal buds or direct all of their energy to the top of the tree and ends of the shoots. This will encourage the inner buds to elongate and add ramification.View attachment 110726 Just wanted to update this post because I know there was some discussion on fall collection for Larch. All the larch I collected last fall are looking very healthy. Fall seems like a safe time to collect so far. This pic is an update as of today of the larch above collected last oct.
