How to Prune Banana Plants

By Elton Dunn ; Updated September 21, 2017
Banana plants require regular pruning.

Banana plants (Musa) require regular pruning to prevent the banana mat from growing too large and to remove dead leaves and spent stalks from the plant. Gardeners must prune their banana plants regularly, removing both dead growth and new growth as they observe it. Both ornamental banana plants and fruiting banana plants can be pruned in the same manner. Since banana plants only grow in tropical areas, they can be pruned at any time without being left vulnerable to cold damage.

Allow the stalk on your banana tree to bear fruit, then harvest the fruit when it's ripe, typically 75 to 80 days after it develops, according to Purdue University. At this time the fruit should be light green. Harvest the fruit by cutting it with a sharp knife.

Cut down the stalk that produces the fruit at its base. Once a stalk bears fruit it will never bear fruit again.

Chop the cut stalk into small pieces, then scatter then around the base of the banana plant to work as mulch, advises the University of Florida.

Thin out the amount of stems produces by your banana plant. The University of Florida suggests having one half-grown stem, one mature stem and one baby stem--called a "peeper"--per banana plant. Cut off extra stems using your knife.

Dig out the rest of the unwanted growth using a small shovel, or stab it with a sharp trowel. If you simply cut off unwanted growth, it will regrow very quickly.

Prune off dead leaves on the banana plant, which will be tan-colored. To allow the fruit to develop properly, prune away leaves that rub up against the fruit cluster. Banana fruit requires sun to ripen.
