- Summer · Jun–AugEvery 6 to 8 days
- Winter · Dec–FebEvery 11 to 17 days
Use room-temperature water and let any excess drain. Never leave the pot sitting in standing water.
Adjust the timing for the light at the plant, the pot’s size and material, and the humidity indoors. Terracotta dries faster than glazed ceramic.

Light and placement
Bright, indirect light
Corn plant thrives in bright, indirect light. Direct midday sun can scorch the leaves. Place it 1–2 meters back from an east or west window, or behind a sheer curtain on a south window.
Feeding
During active growth, feed monthly with a balanced liquid fertilizer at the label rate. Reduce or stop feeding in winter.
Temperature & humidity
Climate18–27 °C (64–81 °F)
Humidity40–60%
During leafy growth, aim for 18–27 °C (64–81 °F). For routine indoor care, keep it above about 13 °C (55 °F) and avoid cold drafts. This is a care guideline, not an exact damage threshold. Cooler overwintering depends on the species and its rest conditions.
It does best at 40–60% humidity. It doesn’t need misting.
Common problems
Yellowing, drooping, and dry edges often point to watering or drainage. Compare the signs before changing the routine.

How much light does a corn plant need?
Corn plant thrives in bright, indirect light. Direct midday sun can scorch the leaves. Place it 1–2 meters back from an east or west window, or behind a sheer curtain on a south window.
Is corn plant safe for cats and dogs?
The plant contains saponins. Chewing it can cause oral irritation, drooling, and vomiting. Keep corn plant out of reach of pets, or pick a non-toxic alternative like Japanese aralia, aluminum plant, friendship plant, or nerve plant.
Why is my corn plant turning yellow or drooping?
Yellowing, drooping and brown tips can have several causes. Check the potting mix before adding water and follow this plant’s watering and rest instructions. If the mix is still wet, do not add more water. Check drainage and roots, then light, humidity, water quality and pests. Faded color or webbing alone does not show that the roots need water.
