Coconut Palm (Cocos nucifera) Yellowing: Light, Water, and Forgiveness

Two Main Causes

1. Too much direct sun (if outdoors) or too little light (if indoors).
2. Watering errors: Coconut palms are unforgiving—both over and under cause yellowing.

Light Fix

• Outdoors: light shade, not full sun.
• Indoors: sunniest windowsill (south/west).

Watering Protocol

• Let soil surface dry, then water thoroughly.
• Never let sit in drainage water.
• Never let dry out completely.
• Use distilled/rain water (sensitive to salts).

Pot & Soil

Still in nursery pot? Repot in 1:1 potting soil:perlite, 1–2 inches larger. Ensure drainage.

Difficulty Level: High

Coconut palms are not great long-term houseplants. They need tropical humidity, intense light, and perfect watering. Enjoy it while it lasts, but don't be discouraged if it declines.
