How often should tomato seedlings be watered?

When they are just planted, you can water them a little, and then water them once every two to three days. A little each time is enough. After fifteen days, when the tomato seedlings grow to half the length of a palm, water them once a day and a half, about 30 ml each time. When watering, it is best to use well water or diluted manure water. If it is diluted manure water, do not water the roots, just water the sides.

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.

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.
