Dracaena Marginata Yellowing: Overwatering Diagnosis and Correction

Classic Overwatering Symptoms

Yellowing lower leaves that point downward, leaf drop cycles, and a moisture meter reading "dry" while the plant declines—these indicate water accumulating at the pot bottom despite dry surface readings.

Drainage Verification

• Confirm pot has drainage holes
• Use a saucer and empty it 1 hour after watering
• If too heavy to lift, use a turkey baster to remove excess water
• Consider repotting into a container with better drainage

Seasonal Watering Adjustment

Light Requirements

Bright indirect light year-round. In winter, ensure the room is well-lit—Dracaenas don't go fully dormant but slow significantly in low light.

Irreversible Damage

Yellow leaves won't regain green color. Focus on preserving healthy foliage and encouraging new growth from the crown. Prune yellowed leaves once they're fully brown.
