I have a Schefflera, Umbrella Tree. This thing is 9feet and still growing.I cant fit it through the door when I bring it in so it does not freez so I drag it into the garage. It lost a few top leaves in the process. Anyway, can you prune one of these things or is that a no no. I have a feeling its a no no. It looks like this ; http://aggie-horticulture.tamu.edu/interiorscape/brassaiaact.html Except mine is a LOT biger and growing at a slanted angle in a big pot.
