Don't know. Will let you know soon though. Have to dig it up, it has escaped thru the colander and is well established in the ground. I made a collar and added more soil as the trunks began to layer above the plate to keep the roots from drying out. The trunks in a couple places are now just touching and probably next year with a cut back will start to merge together. Then I will need to begin to think if I want to make a single trunk tree or work this into a five tree clump?????
