Dragon Tree problems & how to fix them
Dracaena marginata
Drooping, yellowing, brown tips, or a plant that just won’t thrive? Here are the most common Dragon Tree problems, what usually causes them, and how to turn things around.
Common problems
Overwatering
The most common cause of decline — soft canes and yellow leaves. The soil is staying wet longer than the plant can handle, starving roots of oxygen. If caught before roots start rotting, the fix is simple - let the soil dry out and adjust the routine - and most plants bounce back within 2-3 weeks.

Crispy tips (low humidity)
Fluoride and accumulated salts brown the fine leaf tips. Brown, dry leaf tips caused by air that is too dry for the plant, common in heated or air-conditioned rooms. Existing crispy tips never turn green again, but with higher humidity new growth should come in clean within a few weeks.
Root rot
Slow-draining soil in a cool room rots the roots quickly. A fungal or bacterial infection of the roots, almost always triggered by soil staying wet too long. Caught early, most plants recover within a few weeks after repotting; if most roots are already mushy, recovery is uncertain.

Spider mites
Mites like the narrow leaves in dry rooms; look for fine speckling. Tiny sap-sucking mites that thrive in warm, dry air and leave fine webbing and speckled leaves. Caught early they are very treatable; most plants recover fully within 3-4 weeks of consistent treatment.

The mistakes that most often kill it
- Loving it to death with weekly watering.
- Letting it stand in cold, wet soil through winter.
- Placing it where chewing pets can reach it — cats find it irresistible.
