Pruning a Mature Corn Plant (Dracaena fragrans)

A 14‑year‑old corn plant that's hitting the ceiling needs pruning—it won't stop growing on its own. Pruning now won't kill it, but older woody stems may be slower to sprout new growth than younger ones.

Where to Cut

New growth emerges just below the cut, so prune each stalk to the height where you want new foliage to appear. You can cut back quite hard; the plant will respond with fresh shoots.

Propagating the Tops

The removed tops root easily in water or damp potting mix. Shorter tip cuttings root more reliably than long, woody sections.

Why Leaf Tips Turn Brown

Brown tips result from inconsistent watering (too dry or too wet), low light, compacted roots, or mineral buildup from hard water or excess fertilizer. If your tap water is hard, use filtered or distilled water.

Regular pruning keeps a corn plant manageable and attractive for decades.
