I have three indoor avocado trees that I have grown from seed (pictured). I have cut two off after they got fairly high and both have started a new branch (the one on the right has barely started its branch and the one on the left and in front has awhile ago). The one in the back I haven't cut off the stem, but I have pruned it extensively after the leaves got really big. It is now starting with some new growth at the top. I have also been picking off the leaves of the one in the front left.
I don't want them to get very tall and I want them to branch out, but so far they don't like to grow leaves or branches unless it is more near the top. How can I do this? Is there any way to get the little bumps (that are present every so often up the stem) to turn into branches? How should I be pruning these trees - branches and leaves? Is what I have been doing so far completely wrong?
