When you repot the tree try repotting at an angle, that will give you one direction, then you can work the branches into more movement based on what that gives you. I would not reduce anything until you've settled on what you'd like the tree to be. For now just enjoy the flowers, and keep the tree healthy and growing strongly.I have been looking at pictures of more mature trees, they all have nice movement in the trunk or multi trunks.
I am concerned at the moment that the trunk on mine is straight, it is not pliable at all so do not think I can bend it. Is the answer to chop it? I believe after it has finished flowering is a good time?
Is there any other option? Also should I reduce the branches now?
Well sure, if your goal is to thicken the trunk and/or make a larger tree, then ground or Anderson flat type of growing is the fastest way to get there. But there are plenty of trees that have been container grown for their whole life that can and do make stellar bonsai. It just depends on how fast you want to move the tree and your goal for the material.I've never had a cherry tree but am keeping an eye out for suitable material. I'm wondering if this posted tree would benefit from being transplanted into the ground for a season or two? I'd like to know what those more experienced with cherry trees think.
Only thing I can think of is fungal and insect issues, as they are susceptible. And also read the post above this about the delicacy these trees should embody, which ground growing doesn’t always give.I guess my question was if there were any reasons not to ground grow a cherry tree. I can't imagine any but...
