Troubleshooting
Curry Leaf Plant problems — and how to fix them
Curry Leaf Plant (Murraya koenigii) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Winter leaf drop / dormancy
Semi-deciduous in cool conditions; leaves yellow and drop below about 10C. This is usually normal dormancy, not death — reduce watering, keep it warm and bright, and foliage re-flushes in spring.
Interveinal yellowing (chlorosis)
Yellowing between green veins in cool weather or alkaline soil often signals iron/nutrient deficiency. Keep soil slightly acidic, ensure warmth, and apply a chelated iron or balanced feed during the growing season.
Root rot from overwatering
Soggy soil and poor drainage cause wilting, blackened roots and collapse. Always let the mix dry between waterings, use a free-draining pot, and water sparingly in winter.
Mealybugs and scale
White cottony mealybugs and brown scale cluster on stems and leaf undersides, leaving sticky residue. Wipe off, dislodge with a water jet, and treat repeatedly with neem oil or insecticidal soap.
Spider mites
Fine webbing and stippled, dull leaves appear in hot, dry indoor air. Raise humidity, rinse the foliage, and treat with neem or insecticidal soap until cleared.
Asian citrus psyllid host
As a Rutaceae (citrus-family) plant, it can host the Asian citrus psyllid. In quarantine regions, do not move plants or foliage across boundaries; check local agricultural rules before sharing cuttings.
