I live in Chennai (India - temp day high -35 degree C, night low -27 degree C). I have planted eggplants in my terrace in growing bags. Soil composition soil 50%, coco peat 50%. Vermicompost and cow dung. I use a seaweed extract as foliar spray once in 10 days. Plants are healthy but the buds bloom dry and fall off. To date have not gotten a single fruit. Please help

Excessive nitrogen (such as from cow dung) could also inhibit fruit production, but since your plants are producing plenty of flowers this is probably not the case.
