Answer: How perplexing! From your description it sounds like a wilt problem, but since Big Girl is resistant to both Fusarium and Verticillium there may be something else going on. I would suspect a possible problem at root level; you might dig one up and see if the roots have expanded into the potting soil (or if they are totally crowded and need to be potted up) and be sure the soil is draining the way it should. If that seems normal, you might want to take one to your County Extension (837-1402) for a definite diagnosis.
