It is best to water tomatoes every few days.

How often should tomatoes be watered?

After the tomato seedlings bear fruit, start watering when the first fruit is the size of a walnut. Generally, water them once during the seedling stage before transplanting them. Control the water until the first fruit cluster swells to a size of 2-4 cm when the straight stem of the young fruit is reached. After that, irrigate every 10-15 days depending on the seedling conditions and soil moisture.

Tomatoes can be watered under the film as needed to avoid lowering the ground temperature. As the plants grow and develop, the number of fruits increases, the ventilation increases, and the transpiration increases. The interval between watering days should be shortened and the amount of watering should be increased to keep the soil dry and moist or water it mainly when it is wet.

What water should be used for tomatoes?

Tomatoes should be watered with unpolluted water or natural rainwater. In addition, when watering them, you should pay attention not only to the method and time, but also to the water quality.

1. Well water : It is very suitable to collect rainwater in the rainy season and use it to water tomatoes. Rainwater is neutral water with a high oxygen content, which can prevent the soil from becoming hardened and make the plants grow stronger.

2. Drainage : Pay attention to draining stagnant water during the rainy season. If water accumulates for a long time, it is easy to be infected by fungi and cause root rot, which will affect growth.

What to do if you overwater tomatoes

1. Potted plants : If they are planted in pots, move them to a ventilated place and increase the light to allow the water to evaporate as quickly as possible.

2. Planting in the ground : If it is planted in the ground, drainage should be done. Loosen the soil more often and ventilate more often, so that the water will evaporate faster and reduce damage to it. If the water accumulation is serious, it is recommended to add new soil to help absorb water.
