I have tried several varieties of those small, striped green Thai eggplants, and none produced well, or grew very large, right next to other varieties that did great in (almost) the same soil and other conditions. So I had given up on them, until I had such incredible eggplants in the earthboxes last season, and I thought that maybe they would grow well, too. Not much luck, however, and it seems that, much like many eggplants this season, and many in the past as well, they were stopped when the heat got into the 90's, even though it was not as bad as in past years, and didn't even stop my tomatoes. However, several varieties of EP started producing again in the last couple of weeks, and I'm assuming it is from the cooler weather. Neon and Hari produced right through the summer heat.
I never trim eggplants, but then, I only have about a 5 month time for them to grow here. I think I snipped the top of the Hari this year, when it got over 7 ft tall, figuring it had gone up enough on that fence! The neon just spread out, and I let it go.
