How to Prune an Overgrown Corn Plant (Dracaena fragrans) Without Killing It

Managing a Too-Tall Corn Plant

Corn plants (Dracaena fragrans) are popular indoor trees, but they can outgrow their space and end up too tall for the available light. When the foliage no longer receives adequate light, the plant becomes leggy and sparse. The good news is that you can safely reduce its height without harming the plant.

Light Requirements First

Before you prune, note that corn plants prefer bright, indirect light. They do not like direct sun shining on their leaves. Ideally, place them about six feet away from a south-, east-, or west-facing window. If your plant is stretching for light, moving it to a better spot may help, but if it’s already too tall, pruning is the solution.

Simple Height Reduction

To simply shorten the plant and discard the top portion, use a sharp pair of pruning shears and cut the main trunk at the desired height. The plant will respond by producing new growth just below the cut, eventually becoming bushier.

Saving the Top – Air Layering

If you’d like to root the removed top and grow a second plant, air layering is the most reliable method, especially during the growing season. This technique encourages roots to form on the stem while it’s still attached to the mother plant. Detailed step-by-step instructions for air layering a corn plant are available at the Texas A&M AgriLife Extension website: Air Layering Guide.
