When harvesting banana, don’t cut the trunk to the ground. Leave 1 to 1.5 meters standing. Why?
Well, that will help nourish the sucker left behind to grow faster and healthier. That is because the old uncut trunk still contains a lot of nutrients and water. The water is particularly useful during the dry season because it will provide the moisture needed by the sucker or suckers.
Dr. Gus Molina, the banana expert, says that when you cut the trunk to the ground, whatever sucker or suckers that remain wlll grow very slowly. It is also possible that with the old trunk retained, new suckers will still develop.
