Troubleshooting
Thai Aubergine problems — and how to fix them
Thai Aubergine (Solanum melongena 'Thai Green') 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.
Won't fruit without enough heat
This is the most heat-demanding of common aubergines; cool summers give leaf but few fruit. Grow under glass or in the hottest spot and start plants early indoors.
Spider mite and aphids
Warm, dry greenhouse air favours spider mite; aphids mass on soft growth. Maintain humidity, inspect leaf undersides, and deploy biological controls promptly.
Blossom-end rot
Sunken brown patches on fruit from inconsistent watering and calcium uptake. Keep soil moisture steady rather than relying on calcium feeds.
Picking at the wrong stage
Fruit is eaten immature; left too long it yellows, hardens and grows bitter and seedy. Harvest young while green-and-white and firm to keep the plant producing.
Prevent thai aubergine problems before they start
Most thai aubergine issues are care-mismatch, not bad luck. Dial in the basics:
