I know tomatillos need two plants in the area to cross pollinate and set fruit. So, I bought two plants and planted them next to each other. They've been flowering, and the tomatoes next to them flower and set fruit and produce fruit!, but they're not setting fruit. Do the tomatillos just need more heat or less water or what????
Basically, do I keep them in when I pull out the tomatoes (they didn't do too well last year when I kept them through the summer, so I'm going to replace them in August) or do they come out at the same time?
