Tomatoes in gardens have an advantage over container plants -- they can spread their roots out far and deep in search of water. Even so, the same rule of thumb about even soil moisture applies. Tomato plants need about 1 to 1 1/2 inches of water each week to fruit, according to Ohio State University. There's no need to measure, so long as you maintain an even soil moisture. At the beginning of the growing season, this may mean watering in the morning until the soil is thoroughly damp and remains damp all day.
Mulch around tomato plants in the garden so you don't have to hoe weeds, potentially severing tomato roots in the process. Water deeply, but don't wait until the soil is bone dry to water again. If your tomato is in a large container, you may have to water more than once a day during the worst heat. Any plants -- flowers, herbs or vegetables -- growing in containers will dry more rapidly than if they were in the ground. How often you water will depend both on the size of the container and what you are growing.
