Use a citrus fertilizer on bananas in March, June, and October. Water plants when it is dry. Bananas can form within 20-24 months after emergence of shoots from the ground. This happens only if they are well fed. Cut the old stems down after fruiting.
New shoots continue the production cycle.
Q. Something is eating my bananas . They have holes in them. A. Bananas are not normally troubled by many insects. If fruit is left on the tree too long, various scavenger beetles will feed on it. These are normally considered good guys, like nature's garbage men.
