How to water tomato seedlings

1. Observe the soil in the pot : see if the soil is white. If the soil is white, it must be lacking water and needs to be watered in time.

2. Look at the branches : You can see if there is any dryness on the branches of the tomato. If so, it is a sign of lack of water and you need to water it in time.

3. Check the roots : Are the roots a little dry? Generally, if the main trunk at the top of the roots is dry, it is also a sign of lack of water.

Precautions for watering tomato seedlings

1. Watering frequency and amount : When planting seedlings, water should be applied slowly and timely. Water should be properly controlled during the growth period of low-temperature tomatoes. When the first tomato fruits begin to swell, water should be gradually increased to ensure that the soil moisture content in the greenhouse is not less than 20%. Peak period.

2. The difference between watering on cloudy and sunny days : On sunny days with high temperatures, the amount of water should be gradually increased; on cloudy days, less water should be irrigated or no watering should be done; on continuously cloudy and snowy days, no watering should be done; when the weather changes from sunny to cloudy, the amount of water should be gradually reduced and the time should be extended. It is best to combine watering with fertilizing, and ventilation should be reasonable after fertilizing.

What to do if tomato seedlings are overwatered

1. Potted tomato seedlings need to be moved to a ventilated place, and the light should be increased to promote the evaporation of water as quickly as possible.

2. If the ground-planted tomato seedlings are watered too much, they need to be drained, loosened the soil more often, and ventilated more often, so that the water will evaporate faster and reduce damage to them.

3. If the water accumulation is serious, it is recommended to add new soil to help absorb water.
