Kaffir Lime problems — and how to fix them
Kaffir Lime (Citrus hystrix) 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.
Leaf drop from cold or overwatering
Sudden chills, drafts, or soggy roots cause leaves to yellow and drop. Keep above 10°C, away from cold windows and heaters, and let the soil surface dry between waterings.
Nutrient deficiency (yellowing leaves)
Interveinal yellowing signals iron, magnesium, or nitrogen shortfall common in container citrus. Feed with a balanced citrus fertiliser containing micronutrients through the growing season.
Scale and spider mites indoors
Overwintered indoors it is prone to scale insects, mealybugs, and spider mites in dry air. Inspect regularly and treat with horticultural soap or oil at the first sign.
Root rot in heavy soil
Slow-draining mixes and overwatering cause root rot. Always use a gritty citrus compost and a pot with ample drainage holes.
