I have 2 eggplants going in my garden right now. I'm pretty sure they are the normal purple tear-drop shaped egg plants. My friend gave them to me as she had extras in her greenhouses. I've hardened them off, transplanted them, and put climbers over them. Over the past 4 days we've had alot of rain. The bottom leaves are looking a little yellow.. is that OK? Just exactly how big do eggplants get? Any tips?
