Here is what I did. Once year I had a long trunk, about 2 feet high with a tiny bit off green sticking out the top of my Maurelli that wasn't doing anything and looked awful and I wanted a shorter plant. Since I had a spare of the same tree, I cut the trunk down to about 6 inches above the soil. I noticed a month or so later that pups were coming up like crazy and the main trunk started pushing out new leaves. 4 leaves later from the main trunk I had a nice good looking short plant and a pot full of pups. Alas, all the Maurelli's succumbed to a freakish, REALLY hard freeze the next winter.
Now whether this was a fluke I don't know. I haven't done it since though I'm considering doing with with my Super Dwarf Cavendish mother plant because it's starting to look awful.
