 I've lost so many tomato plants this year, and even some I've replaced them and lost them, and in different beds with different soils and some even in pots and planters. They just seem to just wilt up for no reason. It has nothing to do with watering. It'd be immediately after a rain even. But there's no yellowing or brown spots or anything on the leaves that look like a disease. They just seem like they just wilt up. The whole plant just wilts? Yeah, yeah, the whole plant. Yeah, that's weird.
