Corn Plant Leaves Turning Yellow? Brown Tips, Curling and Drooping — Causes and Fixes
Why corn plant (Dracaena fragrans) leaves turn yellow, get brown tips, curl or droop, and how to fix each problem.
The corn plant (Dracaena fragrans) is tough, but it shows stress in its leaves quickly. Start by noticing which leaves are affected and what the damage looks like — that usually points to the cause.
Only one or two lower leaves turn yellow
Older leaves at the bottom of the stem yellowing and dropping one at a time is normal aging. If new leaves keep coming from the top, there is nothing to worry about. Pull off or trim fully yellow leaves.
Many leaves yellow at once and the soil stays wet — overwatering
This is the most common cause. Corn plants need the soil to dry partly between waterings; if the soil never dries, the roots cannot breathe and start to rot. Limp yellow leaves, a soft base of the stem or a sour smell from the soil all point to overwatering.
- Push a finger 2–3 cm into the soil and water only when it feels dry (roughly when the top half of the soil has dried)
- Empty the saucer after watering
- Water even less often in winter
- If the base is soft, unpot the plant, cut away black mushy roots and repot in fresh soil
Brown leaf tips
Brown, dry tips and edges are especially common in dracaenas, including the corn plant. Typical causes are soil left bone-dry for too long, salt build-up from too much fertilizer, and fluoride in tap water collecting at the leaf tips. Dry indoor heating makes it worse.
- Water thoroughly until it runs out of the drainage holes to flush salts from the soil
- Fertilize only in spring and summer, and use less than the label says
- Filtered water or rainwater often reduces tip burn
- Brown tissue will not turn green again — trim just the brown part at an angle, following the leaf shape
Curling or wrinkled leaves — underwatering
Leaves curling lengthwise or looking wrinkled, with bone-dry soil and a light pot, mean the plant is thirsty. Water slowly until the whole root ball is wet; leaves often flatten again within a few days. If water just runs off dry soil, soak the pot in a basin of water for 20–30 minutes.
Drooping leaves — check the soil
Drooping can mean too little or too much water. Dry soil means underwatering; drooping in wet soil means damaged roots from overwatering. Cold below about 10°C or cold drafts can also make leaves droop and turn soft, so keep the plant away from cold windows and doorways in winter.
Pale leaves or faded stripes — light
Corn plants tolerate low light, but in very dim spots new leaves come in small and pale and variegated types lose their stripes. Long hours of strong summer sun, on the other hand, leave yellow or white scorch marks. Bright light filtered through a sheer curtain is ideal.
The right watering interval depends on pot size, light and season. Use the watering calculator on GreenPic's corn plant page to get an interval for your home and a reminder.
