Just take a chainsaw and thin them out. There is no real special way to thin out a clump.Its up to you how many and how much you want when it comes to bananas. Remove all but 1 or 2 pups and chainsaw the rest. Save 1 or 2 mother plants. Remove any bananas that have already produced fruit. Its real hard to kill a banana plant. I have had corms producing pups after i cut them into small pieces, and left out of the ground dry after 4 months.
