How to Control Tomato Plant Rot in Ground

Question

My tomato plant is rotting in ground at the root and plant is dying.

Answer 1

This normally indicated that the soil is not draining well. If you are doing any manual watering, stop for a little while and allow the soil to dry out. The plants only need 2" of water a week so only give them that much.

There may also be a fungus issue in the soil that is causing this. It will not hurt to treat the soil around the plants with a fungicide.
