I have a bunch of trees that were started as cuttings. Most of them grew from the sides outward. I am not sure how to straighten them to look like real trees. I have not seen a video on this subject. Do I just cut the root ball and pick a main trunk and bury the trunk halfway to the way I want it? I think the majority of the time I have been gardening, I have read not to bury a tree's trunk too deep or you will suffocate the roots. Does this not apply to fig trees?
