The Q&A Archives: tomatos

Question: tips of leaces turning brown, plants are 2 or 3
weeks old. They are about 12 inches high. I water
8 minutes every morning. Have done the same for
the past four years and never had brown tips before.

Answer: What you describe sounds suspiciously like Verticillium wilt. The bottom leaves become pale, then tips and edges die and leaves finally die and drop off. V-shaped lesions at leaf tips are typical of Verticillium wilt of tomato. Infected plants usually survive the season but are somewhat stunted and both yields and fruits may be small depending on severity of attack. If in fact this is what your tomato plants have, rotate your crops next year so future tomato plants do not develop the disease and look for seeds or seedlings resistant to Verticillium.

Best wishes with your tomato plants!
