Some people like to grow vegetables such as green cabbage, cabbage and other vegetables at home, so they bought some seedling seeds, but after sowing they found that these green cabbage seedlings were slender, not strong and easy to break. This is what everyone calls small seedlings Legacy question. In the process of raising seedlings, how to avoid the leggy growth of vegetable seedlings and how to remedy them after they grow leggy, let’s take a look at it together.
There are generally four reasons for the leggy growth of vegetable seedlings in indoor planting. The first is insufficient light, and plants have phototaxis. Therefore, we can use the light of LED plant lights to guide growth. Because the seedlings need to be supplemented with sufficient light to promote internal photosynthesis during the germination and growth process, it is generally difficult to ensure sufficient indoor light. Therefore, the use of LED plant fill lights can ensure that there is enough light to promote the growth of vegetable seedlings.
The second is that the planting is too dense, causing the vegetable seedlings to block the light from each other and compete for water. When sowing, because of the close spacing of vegetable seedlings, the nutrient components absorbed by the seedlings during the growth process are not enough, and the light in the soil is less, resulting in uneven growth, so pay attention to the spacing of sowing. For seedlings that have grown densely, you can Properly pull out the denser seedlings, and use the method of thinning to increase the distance and ventilation between the seedlings to ensure sufficient growth space.
Third, the temperature is too high. Indoor seedlings are generally kept at about 20 degrees. If the temperature is too high, you can add some wind sources, such as small fans, to promote the flow of air and ventilation.
The fourth is too much moisture. The leggy growth of vegetable seedlings is also closely related to the amount of watering. It may be because the flowerpot or vegetable seedlings are placed indoors, the evaporation is very small, and the watering is too much, the vegetable seedlings are very easy to grow leggy, so when watering, it should be thoroughly watered at one time, and then water after the soil surface is dry. Ensure that the seedlings have proper moisture without causing leggy growth.
In general, after the seedlings grow leggy, on the one hand, increase the light, reduce watering, and increase ventilation. Another method is to tear off some thin and leggy seedlings, and then add some soil appropriately, and cultivate some soil in the Near the seedlings, a few centimeters thick is enough, you don’t need too much. You can also choose to reseed if the leggy grows too much.
