It thrives in cool moist soil but usually doesn’t reveal its ugly self until the weather turns warm and dry. • Infected plants usually show mild to moderate wilt during the warmest part of the day, but recover at night. With the soil ready, choose plants that are disease-resistant—the acronym "VFNT" on a tomato seed or plant label indicates its resistance to verticillium wilt, fusarium wilt, nematodes, and tobacco mosaic virus. Verticillium wilt of tomatoes can be avoided in many cases by planting resistant varieties, which are labeled V. If you wish to grow susceptible varieties, problems can sometimes be minimized by removing all residue, including roots that may be susceptible, and using soil solarization before you plant.
