Tomato Seedlings

The seedlings need enough water to grow successfully so ensure the soil is damp below the surface so that the roots can spread and establish themselves easily.

Young Transplants

After transplanting the young tomatoes in the garden allow them to soak well. Monitor the soil moisture and prevent them from drying out.

Mature Tomatoes

In hot and humid conditions, to grow tomatoes water the plants more often, and during the rains reduce the watering or skip in case of heavy downpours.

Fruiting Plants

Keep a close watch for under-watering and over-watering as in both cases the harvest will be hindered. Ensure you water your tomato plants just enough without excess.

What Is The Maximum Amount Of Water Required By Tomato Plants?

The guidelines discussed below will help in providing a general overview of the water requirements for tomato plants:

General Watering Requirements

Tomato plants require consistent soil moisture and fluctuations that result in blossom end rot and fruit cracking. Knowing when it’s time to water your tomatoes is crucial.
The weekly water needs of the tomato plants are around 2.5-5cm or 1-2 inches of water during the peak growing season
In hot and dry conditions, the water needs to rise to about 0.5-1 gallon of water per plant per daily
The tomato plants need to be watered twice a day during the hottest time and it can be reduced to once as the weather cools
Aim to moisturize the soil at a depth of around 8 inches or 20cm and avoid watering on the top
Make use of organic mulch to help retain the soil moisture and reduce evaporation, making it less frequent to water your tomato plants.
Monitor the soil moisture and adjust the watering needs depending on the weather conditions and plant growth

Maximum Watering Requirements

In hot and dry weather conditions tomato plants need up to 2 inches or 5 cm of water weekly and this is required to compensate for the rapid evaporation that takes place when the temperatures soar
Splitting the watering application into a daily schedule will require 1-1.5 gallons of water per plant per day
Water deeply and slowly at the base of the plant to encourage deep root growth
Using thick organic mulch will reduce the need for frequent watering
In the case of container-grown tomatoes, they require frequent watering twice a day during extreme heat

Note: Be observant of the weather to determine when it’s time to water your tomato plants. Adjusting the watering frequency depending on weather conditions and growth will ensure the tomato plants receive consistent moisture for thriving even in the hottest and driest weather. You often need to water your tomato plants more frequently during hot, dry spells.

Consistently moist soil

Signs Of Under-Watering

Knowing when to water is important and so the signs of under-watering are discussed below.

Doing this will help you to take corrective action to ensure that the tomato plants receive the right amount of water:

Leaf drop
Wilted leaves
Stunted growth
Fruit drop
Dry soil
Steam weakness
Fungal growth

Best Practices To Grow Healthy Tomatoes

Practice frequent and deep watering techniques, adjusting how often to water based on the plant’s needs and weather.
Water the base of the plants and not the leaves
Monitor the soil moisture regularly
Watering in the early hours of the morning is advisable
