I have multiple eggplants in pots inside my screens. They are all flowering, but none are producing actual eggplants. Am I missing something?
Eggplants tend to spontaneously abort their first flowers. Some species do this on their first flowers to attract pollinators. The after a few weeks they will set fruit. Last time I grew eggplants it took 3 weeks from the first bloom until fruit set. That's also the time I found out I was highly allergic to it's sap.
Cucurbits will start male bloom and then abort all of the early female flowers before they open. It's an interesting biochemical mechanism.
