Troubleshooting
Pomelo problems — and how to fix them
Pomelo (Citrus maxima) 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.
Poor fruit set
Cool summers or insufficient light prevent ripening and reduce sweetness; site in the warmest, sunniest position and overwinter under glass in cool climates.
Spider mites and scale
Frequent on indoor and greenhouse trees in dry air; monitor leaf undersides and treat with horticultural oil or soap.
Leaf yellowing
Iron or magnesium deficiency in pots, or overwatering; feed a complete citrus fertiliser and check drainage.
Frost damage
Foliage and young wood injured below about 4°C; protect or bring containers indoors before frost.
