Wilted tomato plant might be caused by too much rain or various other reasons.

Tomato wilts; not sure what to do

A couple of my tomato plants have wilted. I am a successful gardener mostly by pure luck so I really don't know why I am having problems.

My neighbors are having the same problem with their tomato plants. The only thing I can think of is that all this rain is causing some sort of fungus but I don't see anything on the plant.

Checking a website from the Extension in Lancaster County,, the possible causes are lack of water, vascular wilts, tomato spotted wilt virus, walnut toxicity, or stalk borers. Most of these problems don't have a solution.

My neighbor is spraying her plants with Neem, a botanical insecticide that has a low degree of toxicity and is considered almost nontoxic to humans and animals. It is also completely biodegradable.

I have walnut trees in my yard but for years this hasn't been a problem, although maybe this is going to be a problem this year. Last summer, with the drought, the squirrels buried their walnuts in my garden because the ground in the rest of the yard was hard. I have been pulling out tiny walnut trees growing up from the buried nuts.

I probably am going to have to pull out the affected plants and hope that I can keep the problem from spreading to my other plants.
