A friend at work germinated a Buckeye tree for me in a small plastic pot. I took it home and planted it in a flower bed with the intention of finding a place to put it permanently. Two years later it was about 1' tall and as we were moving, I transferred it to a larger-maybe 3 gallon- pot and took it with us.
Long story short, it is seven years since we moved and I came across the pot. the tree is about 2 and 1/2 feet tall and surprisingly healthy of buds, but it looks like one of those miniature Japanese trees. I kind of like it that way. What can I do to maintain its smallness but insure it survives? Will it eventually seed?
