Mealybugs on Dracaena: Not Mold, and How to Treat

Mealybugs on Dracaena: Not Mold, and How to Treat

The white flaky “fungus” on your Dracaena marginata is almost certainly mealybugs—tiny, cottony insects that cluster where leaves meet stems. Hydrogen peroxide won’t work.

Effective Treatment

Spray a solution of 5 parts water, 1 part rubbing alcohol, and a squirt of dish soap until all surfaces drip. Target every crevice to hit invisible juveniles. Repeat weekly until no signs remain. Thoroughness is the only way to prevent resurgence.

After treatment, ensure the plant isn’t overpotted or overwatered, as stress invites pests.
