How Much Should You Water Tomato Plants Every Day?

Once the fruits have reached full size, begin watering them less often to encourage ripening.

Water Regularly

During the summer months, it is best to water your tomato plant every two to three days. According to the Gardening Know How website, you should water the plants on a regular schedule and then decrease the amount once the fruits are full grown. Water the plants at the roots and water slowly.

Avoid Over-Watering and Under-Watering

If you are not careful about watering your tomato plant evenly, you can cause many problems. An uneven supply will cause blossom end rot, or brown, water-soaked spots on the underside of the tomatoes. Too much water can also make the fruits' skin split. Under-watering will stop the plants from growing to their full potential.

Bottom Line

The Gardening Know How website suggests that you water tomato plants with a hose at the roots to ensure maximum absorption and prevent under-watering. Water your plants on a set schedule to keep yourself from watering too often and ruining the fruit. Remember that natural rainfall counts as watering, so don't overdo it by adding moisture after a rainstorm.
