Getting Bananas to grow from center of large grove
I have a large grove of Bananas that has been growing for about 5-6 years now. Each winter we cut all of the plants to about 2ft in height. We will loose some of the stalks over winter but others will grow from the old stalks once it warms up. The grove keeps spreading every year but the center of the grove is now void of plants. Is there a way to get the center to grow again? Maybe like digging out the center and adding new dirt? It's to the point now where the center that doesn't have any plants is about 5 feet in diameter but all around it there are new plants sprouting up.
