My seedlings have reached six inches tall in the glass container with roots as long as nine inches and spreading leaves. I've been told to cut the tiny trees in half and they'll grow new leaves, and then this is the right time to plant them. I planted one without this method when the roots were still small and it grew to ten inches, growing a different series of leaves that grew large and died. I was told to pinch the plant at the top, which I did, and now a couple of the original nodes seem to be growing. What is the proper way to treat my tiny house trees?
