I planted a 24 inch Musa Basjoo in the ground in May. The poor thing had a hard start with cooler than normal temperatures and 6 rounds of hail. However, it is putting on a new leaf every week. My question is, the trunk of the tree does not seem to be growing at all (in height nor width) and it seems so small for a tree. Is this normal? I water daily and fertilize every 2 weeks.
