Meiwa Kumquat problems — and how to fix them
Meiwa Kumquat (Citrus japonica 'Meiwa') 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 in winter
Caused by cold draughts, dry indoor heat or overwatering during slow growth. Keep the plant bright and stable, and water sparingly in the cold months.
Interveinal chlorosis
Iron or magnesium deficiency, frequent in pots and alkaline water areas. Correct with a citrus feed containing chelated iron and magnesium.
Fruit drop
Heavy drop beyond natural thinning signals drought stress or erratic watering while fruiting. Maintain even soil moisture through the cropping period.
Scale, mealybug and spider mites
Common indoor and conservatory citrus pests leaving honeydew, sooty mould and stippling. Treat with horticultural oil or insecticidal soap and improve ventilation.
