In addition to the amount of water, you should also focus on how to water tomatoes properly to ensure consistent growth. Inconsistent watering of tomatoes can make your potted plants more vulnerable to tomato plant diseases.

Tips For Growing And Watering Tomato Plants

Water At A Slow Speed

The primary objective of daily waterings is to make sure they have enough water and sufficient moist conditions to survive on the soil and execute their physiological functions.

A typical gardening mistake is overwatering the plant and having the water runoff (with topsoil and nutrients). Instead, you’ll need to water carefully so that the water truly permeates into the soil.

When watering a potted tomato plant, make sure your soil gets a proper boost of hydration for a minimum of 6-8 inches under the surface. It will encourage root growth, allowing your plants to absorb more nutrients from the soil.

We highly recommend setting up a drip irrigation system. A drip irrigation system is not difficult to build, and you can set it up for a very little cost – at around $2.

Water At The Tomato Roots

Suppose you usually water tomatoes with a drip hose. In that case, you probably water the tomato leaves rather than pointing the hose towards the ground surrounding the stem because of the drip effect.

Many people apply this conventional method to water the plant leaves because they will appear fresher and nicer. If you want some water to brighten up the leaves, the best time and condition to do it is before dawn.

Suppose your water supply contains contaminants such as chemicals or organic fertilizer for the soil. In that case, watering the leaves brings the worst nightmare since it will destroy your plants by preventing food preparation and optimal functioning under the sun.

Water When The Sun Rises

Regular watering on the leaves and fruits, as previously noted, is a typical watering issue as it might raise the risk of various tomato plant illnesses.

The reason is most tomato plant illnesses become more serious when the humidity is high. Besides, low temperatures create a favorable environment for tomato plant diseases to develop.

For the above reason, it’s clear that nighttime is not the best time to water tomatoes, although tomatoes appear to be drooping.

If you don’t know when to water tomatoes, go for dawn. When you water your plants at this time of day, they are in a great condition to take in enough water and start the photosynthesis process.

Additionally, any water that falls onto the fruit, stem, or leaves can disappear before the noon heat starts burning the plant via these droplets.


Hope this article has helped you answer the question, “How often should you water tomato plants?”. Along with frequent watering, gardeners should also keep an eye on the watering timing, the amount of water, and appropriate techniques to ensure your plant’s consistent growth.
