Tomato plant problem. Why are my plants half wilted?

Question

My tomato plants grew very well and have lots of tomatoes, but now my plants are half wilted and turned brown. Only half of the plant is affected, the other half of it is just as green as if nothing is wrong. There are no bugs or caterpillars on the plants. Does anyone have any idea as to what could be wrong?

Answer 1

Has the growing season ended in your area? Have you watered them? Have you watered them too much? You could try using some fertilizer or plant food, miracle gro makes supplements specifically for tomato plants.

Answer 2

It the half that turned brown is the bottom half, and the leaves turned yellow with dark spots before turning brown, what you've got there is early blight.  It's a fungal problem that shows up from the bottom of the plant, and moves up.  And it's extremely common.

Answer 3

Tomatoes are affected by a number of diseases that cause wilting later in the season...the culprit is usually either southern blight or late blight. There's not much you can do at this point, but in years to come rotate your tomato garden to a new spot where tomatoes weren't grown previously. Work in organic material such as manure or compost to improve the soil health. Since I doubt antifungal treatments will do much (this tends to be a persistant problem) avoid the disease in the first place by planting blight-resistant varieties of tomatoes. (They usually carry the code letter "A" after the varietal name on the plant tag).  

Answer 4

This could be the result of over-watering.  If the roots get too wet and cannot dry out they can rot; depriving the plant of nutrients.  The leaves normally turn yellowish in color first.

Answer 5

growing season for tomatoes is over.
