I know Frank grows these and probably Vicky too but until I moved mine away from the pine trees they never did much.
I went out in the rain just now and cut back my hardy banana. It is a clump of about 5 or 6 trunks the largest one was over 12 foot tall last fall counting the leaves. We have had a very mild winter in northeast oklahoma this year and my stalks had live growth over 4 feet up. They usually die back too the ground and they are not ever mulched. was just surprised.
