Q.Growing Eggplants
My eggplant is growing in a large concrete rectangular pot. It is very healthy with multiple blooms and with morning… full Sun. Not one bloom has produced any fruit. I’ve read that eggplants are “self-polling” and I have gently moved the flowers to do just that..but..to no avail What must be done to make this plant produse even one eggplant?

Lack of fruit is typically due to lack of water or pollination. They need 2 inches of water a week, probably more in a container. And you can hand pollinate with a paintbrush. See below for more:

Eggplant will exhibit this behavior for, almost, any environmental stress factor. Over and under watering are most usual. Heat and humidity will also hinder fruit production. Sometimes, too much nitrogen can be to blame, in rare cases.
