I have Rosa Bianca eggplants that are giving fruit now. How long can I expect them to bear and will I have to take out the plants at the end of the season or will they last until next year?

Eggplants are perennials, but require at least five months of warm weather for fruit production. The optimum daytime growing temperature ranges between 70?F and 85?F. When temperatures rise above 95?F, eggplant ceases to set fruit and may drop flowers or abort immature fruit. Fruit set is also reduced when temperatures fall below 60?F. To keep your plant producing, harvest the ripe fruits when they are the right size for the variety. As long as the weather is warm your plant will develop new flowers which should develop into fruits. Keeping the fruits harvested will keep the plant producing. Eventually, though, it will stop flowering and developing fruits and will die off. I'd encourage it to grow for as long as possible. Hope you have a bountiful harvest!
