My Tomato Plant is Dying!

This is my first tomato plant. Its in a container with holes in the bottom to drain water. I haven't seen any bugs around it. I keep the soil moist, and feed it some plant food. Im super bummed because my tomato plant that has grown almost 5 feet tall, and producing so many tomatoes is dying all of a sudden. It has happened over just a couple days. The tomatoes have been staying green for a few weeks now, so I trimmed some of the leaves, hoping maybe that would help the tomatoes to develop faster. Now, within days, all the leaves have turned brown. It looks like the brown starts in the center of the leaf, then spreads out turning the whole leaf brown. Does anyone know what is happening?

Sorry no one responded to help you out. I am no expert on tomato diseases but you have gotten some kind of infection. It could be wilt or blight. Why don't you post this over on the tomato forum where someone will surely be able to give you a more definitive answer? What variety is this tomato plant?

Good luck.

How hot is it where you are? Also, don't keep it too moist as tomatoes don't really like wet feet (roots). Allow it to dry out some. I would just clip off the dead or dying leaves and continue on. Also, what are you feeding it and how often are you applying fertilizer?

Hi, I had a problem with my tomato plants too. They were doing really well, then all the leaves shrivelled up and the plants eventually died. It can't have been caterpillars because the leaves weren't eaten. I was told that there is some kind of insect that enters the leaf and sucks it dry, eventually killing the plant. This year I'm going to try again, but with netting over the plants, hoping to keep the insects at bay! Hope this helps.

Another potential cause could be drifted sprayed herbicide. Are any other plants unexpectedly showing some dead or dying foliage at the tops or sides? Little puffs of herbicides can drift a long way.

Golf courses, agriculture operations and some lawn services often spray herbicides to control weeds.

maybe it's just at the end of its life. even an indeterminate tomato can only produce for so long before it dies. a determinate tomato will produce all of its fruits within a certain time span and then it's over.

Looks like it is related to overwatering.
I am just a few miles from Benicia. The weather has been really extreme for the last month or so. Really hot for several days, then colder than average, and it even rained one day. Does not usually do that until the end of October.
My tomatoes are still going strong. But they are in the ground, not containers. I am only watering them once a week in the hottest weather, and less as it cools off.

It could be spider mites. Do you see any webbing? Just your description makes me think of this. Mites are microscopic (almost). They thrive in hot dry weather. I haven't had a problem with them this year, but they have been the Bain of my garden, in yrs past.
