How to Care for Corn Plant

Corn plant (Dracaena fragrans) is one of the most forgiving and popular indoor foliage plants, forming a woody cane topped with a rosette of long, arching, strappy leaves often marked with a lighter central stripe. Its upright, treelike form and tolerance of low light make it a reliable choice for homes and offices.

Light

Corn plant does best in bright, indirect light, which keeps its foliage well-colored and its variegation crisp. It also tolerates low light, though growth slows and variegation may fade. Keep it out of harsh direct sun, which can scorch and bleach the leaves.

Water

Water when the top inch or two of soil has dried out, then water thoroughly until it drains from the bottom. Corn plant is sensitive to overwatering, which causes root rot and yellowing leaves, so let the surface dry between waterings. It is somewhat drought-tolerant and prefers to be a touch dry rather than soggy. Use filtered or distilled water if the leaf tips brown, since the plant is sensitive to fluoride and salts in tap water.

Soil & Potting

Grow corn plant in a loose, well-draining potting mix, such as a peat-based houseplant mix amended with perlite or bark for aeration. Choose a pot with drainage holes. A slightly snug pot is fine, as this plant does not mind being somewhat rootbound.

Humidity & Temperature

Corn plant prefers warm indoor temperatures, roughly typical room warmth, and dislikes cold drafts and temperatures below the mid-50s Fahrenheit. It appreciates moderate to higher humidity; in dry indoor air the leaf tips may brown, which occasional misting or a nearby humidity tray can help offset.

Feeding

Feed lightly during the growing season, spring through summer, with a balanced, diluted liquid houseplant fertilizer about once a month. Reduce or stop feeding in fall and winter when growth slows. This is a slow, light feeder, and over-fertilizing can contribute to leaf-tip burn.

Propagation

Corn plant is easily propagated from stem cuttings. Cut a section of cane, let the cut end callus briefly, and root it in water or moist potting mix. Both the top rosette cutting and sections of the bare cane will sprout new growth. Warmth and bright indirect light speed rooting.

Repotting / Pruning

Repot every two to three years, or when roots fill the pot, moving up one pot size in spring. To control height, cut back the cane at the desired level; the plant will branch and produce new rosettes below the cut. Remove yellowing or spent lower leaves as they age. Wipe the broad leaves periodically to keep them dust-free and photosynthesizing well.

Common Problems & Pests

Browning leaf tips are the most common complaint, usually from dry air, fluoride or salts in tap water, or inconsistent watering. Yellowing leaves and soft stems point to overwatering and root rot. Watch for spider mites, mealybugs, and scale, especially in dry indoor conditions; treat with insecticidal soap or by wiping the foliage. Drooping can signal either underwatering or cold exposure.

Seasonal Care Tips

In spring and summer, keep the plant in bright indirect light, water when the top inch or two dries, and feed monthly during active growth. In fall and winter, reduce watering as growth slows and stop feeding. Keep it away from cold windows, heating vents, and drafts year-round, and raise humidity during dry winter months to prevent leaf-tip browning.
