I have some japanese maples, some ginko biloba, and some seiju elms that i have had in the ground since last spring. They have several years left to develop, but am trying to learn more about what to do to them while in the ground. I guess as long as there are not two branches coming out from the same point in the trunk, that will keep any bulges from developing. I would think that most branches i have now would be too large for the finished tree once the trunk gets to the size im wanting, so im sure new branches would have to be grown. I like the idea of cutting around the rootball with a spade shovel every year or two to get the roots developing closer to the trunk. What time of year would be the best time for this? And, should it be done every year, or every other for the most benefits? THanks for any help, or other ideas for growing in ground.
