The tops of several plants are wilting, looking like they need to be watered, even after being watered for over an hour. The leaves at the bottom of the plant have turned yellow, then brown until they die. The plants have great fruit on them, but we're concerned that the plants will die before the fruits are harvested. We have 3 raised beds, 2 of those beds have some plants that are wilting, and all 3 have the yellow/brown leaf thing going on. another bed, not raised and planted later, seems to be fine. The stalks seem to be fine, and there doesn't appear to be any insect infestation. The plants are celebrity, whopper and better boy.
