Tomato Plants Died Over Night, Ants Everywhere
I have ants in my garden. Two plants died overnight. Is this caused by the ants?

Generally, when you see ants on plants, they are not attacking the plant but rather feeding off aphids (which are attacking the plants and happen to love feasting on tomatoes). Inspect for aphids. If you get rid of the aphids, the ants will go as well. Neem oil is good for treating them.

If you do not see aphids, you can try diatomaceous earth or uncooked grits around the base of the plants. They both help to kill ants.
