My Chilli plant leaves are curling, the flowers are falling, and a lot of ants are traveling all the way to the place where the new leaves and flowers are shooting. I have tried burying banana peel pieces in the soil, but no go. Any help appreciated.
Inspect the plant closely - its likely its infested with aphids (blackfly, greenfly, whitefly) of one sort or another, and ants like to collect the honeydew the aphids produce. The ants are a symptom of infestation. Spray with neem or a suitable insecticide for edible plants available where you are.
