How should seedlings be watered when growing in seedling trays?

When watering the seedlings in the seedling tray, choose the appropriate time. It is best to do it in the morning or evening on a sunny day. Avoid midday on a sunny day. Otherwise, the temperature will be too high and sudden watering will irritate the seedlings, making it difficult to absorb the water and affecting their growth. . Also avoid rainy weather, which will cause high humidity and require water to be turned off.

The seedlings in the seedling tray grow slowly and weakly, so you need to pay attention to the frequency of watering them. If you water frequently, the seedlings will easily grow leggy, which will reduce the resistance of the seedlings. The frequency of watering should be determined according to the growth of the seedlings. It is best to wait until the seedlings are wilted and soft before watering. This will absorb the water well and facilitate growth.

The seedlings in the seedling tray grow weakly and are sensitive to water temperature. Pay attention to the water temperature when watering them. Generally, groundwater is used, which has a relatively low temperature. If the seedlings are watered directly, the roots will be stimulated and the root growth will be affected. It is recommended to collect the water in advance, dry it for two or three days, and then water it when the water temperature is close to the soil temperature. This way, the water can be well absorbed after watering, which is beneficial to growth.

When watering the seedlings in the seedling tray, do not water them head-on. Generally, you use a watering can to spray water, and spray water evenly from one side to the other. The nozzle should move evenly and maintain a uniform speed to ensure that each seedling can absorb water, so as to promote the vigorous growth of the seedlings.
