repotting Japanese maple
Comments (1)I would keep things pretty cold (28-30 degrees F) for a while longer, if I were you. With the heater and shelter, you're forcing the maples to bud a bit too early. Before you know it, you will be dealing with fully leafed out maples when there is stil alot of danger from hard freezes still around. I would keep things cold to keep the trees from leafing out until at least the end of March. You want as little danger of frosts and freezes as possible when Japanese maples start to leaf out--even if you have heated porch. When the plants leaf out, they need sunlight. You will get alot of long weak growth in such conditions that won't help bonsai training along very much....See MorePlease help me with soil for my new Japanese Maple!

Comments (2)Pretty much what HT said ....There's a difference between repotting and potting up. Repotting includes root pruning and a fresh change of soil after removing all or most of the old soil. Potting up is simply transplanting the tree in a larger pot with a slightly larger soil volume. Potting up ensures continuation of the limitations inherent in congested roots, repotting relieves the tree of that condition. Unless you encounter some sort of emergency, there is little reason to repot a deciduous tree while it's in leaf - the potential problems are many. Pot up any time, but it's best to do it when the tree is growing well or about to put on the spring flush. Note that the growth "spurt" you usually see after potting up isn't a spurt at all. It's an indication that root congestion is and has been limiting your plant's growth and vitality. The 'spurt' is simply a result of the tree filling the extra space with fine roots, which temporarily allows it to grow somewhat closer to its genetic potential.

Comments (6)Washington DC has humid and rainy summers like those of the eastern Asian native habitat of Japanese maple. Even in the wild it is typical for Japanese maple to be a forest understory tree. Wild type green seedlings are also much tougher than many fancy garden forms. Sacramento is very hot and dry in summer. There is also the matter of mineral salts in the irrigation water, a problem for Japanese maples in arid and semiarid regions. Plants that are common in gardens up here may be seen almost exclusively in certain locations with unusual conditions down there, such as the extensive and heavily watered lawns of the California State Capitol grounds. Even there growth of such kinds may be noticeably less enthusiastic than in more suitable climates elsewhere. The Sunset WESTERN GARDEN BOOK says a good indication of a locale being suitable for Japanese maples is the presence of evergreen azaleas in plantings there. Large, established and healthy Japanese maples in the vicinity, under similar site conditions would also of course be a good hint. For shade you probably really want something much more likely to thrive and develop rapidly under your conditions. Even where naturally suited Japanese maples are slow-growing trees that may take decades to produce a significant shadow....See Moretapla (mid-Michigan, USDA z5b-6a)
