How to Care for Dracaena (Corn Plant and Dragon Tree)
The short answer
Most dracaenas — including corn plant (Dracaena fragrans) and dragon tree (D. marginata) — grow best in bright, indirect light but tolerate lower light. Clemson Extension's watering rule: allow the soil surface to dry to the touch, then water thoroughly, and avoid cold water.
Brown or scorched leaf tips on dracaena are commonly fluoride damage — the genus is highly sensitive to fluoride, which shows as yellowing tips or margins and dead, scorched areas. Clemson recommends avoiding high-perlite potting mixes, keeping soil pH at 6.0–6.5, and skipping fertilizers containing superphosphate.
What a Dracaena Is
Dracaena is a genus of cane-forming foliage plants; the corn plant and the dragon tree are the most common indoor forms. They grow slowly into tree-like plants and handle typical home conditions well.
Light
Bright, indirect light is best; many dracaenas, notably the dragon tree, also tolerate low light. Expect thinner growth in dim spots.
Watering, Soil, and Drainage
Let the soil surface dry to the touch between waterings, then water thoroughly. Avoid cold water. Use a standard commercial houseplant mix in a pot that drains — root rot follows poor drainage or overwatering.
Feed with a liquid foliage-plant fertilizer once a month in spring and summer, or use time-release pellets.
Brown Tips and Fluoride Sensitivity
Dracaenas are highly sensitive to fluoride. Damage appears as yellowing of the leaf tips or margins and dead, scorched areas.
- Avoid potting soils with high perlite content
- Keep soil pH between 6.0 and 6.5
- Do not use fertilizers containing superphosphate
- Low humidity adds to tip browning — mist foliage occasionally if indoor humidity drops below 30–40%
Humidity and Temperature
Aim for daytime temperatures of 60–70°F with nights about 10°F cooler. If humidity falls below 30–40%, the plant benefits from occasional misting.
Pruning and Propagation
Leggy canes can be cut at the desired height — new leaf growth emerges below the cut. Dracaenas are easy to propagate by air layering, tip or stem cuttings, or by removing and rooting basal shoots in spring or late summer.
Common Problems
- Brown/scorched tips: fluoride sensitivity or dry air (see above)
- Root rot: poor drainage or overwatering
- Pests: scale insects and mites are the primary problems
⚠ Dracaena is commonly listed as toxic to pets — check the ASPCA toxic plants database before keeping it within reach of cats or dogs.
