Can sunflower seedling bask in the sun, how does ability grow up healthily?

Excessive light: If the green ingot in the long-term light too strong in the environment, the leaves are easy to be yellow. At this time, it needs to be moved to a cool environment for maintenance. Overwatering: Overwatering can cause water to accumulate in the potting soil, damaging the roots of the plant and causing yellow leaves. At this time, it is necessary to loosen the soil for it, and put it in a cool and ventilated place to raise. Too much fertilizer: too much fertilizer can also cause it yellow leaves. At this time, it is necessary to stop fertilizing and replace it with new soil.

1. can you bask in the sun

Sunflower itself is very fond of light, even small seedlings can not do without light.If the seedling stage does not see the sun for a long time, it is easy to grow in the shade, which will affect the later flowering.But also cannot bask in strong light, cannot insolate, otherwise young plant can be basked in wither.Generally, two or three hours of sunshine in the morning will do, and the sunshine at noon must be blocked.

2. how to grow up healthy

1. Humidity: If you want the seedlings to grow healthily, nature cannot do without moisture, so you need to moisturize them.However, the water consumption in seedling stage is less, so we should pay attention to the number of watering.Generally, it is OK to irrigate once in two or three days, so that the soil can not accumulate water, otherwise it will hinder breathing and affect growth.

2. Temperature: It is not cold-resistant, and the cold resistance of the seedlings is even worse.Pay attention to the temperature, it is best to maintain about 18 degrees, not too low.If the temperature can not meet the demand, it is recommended to cover plastic film to keep warm, open ventilation during the day, and then cover at night to avoid frostbite.

3. Precautions

Usually, the soil used in cultivation contains certain nutrients, which can meet the needs of the seedling stage, and it is also tolerant to poor soil, so there is no need to fertilize at this time.If fertilizer is applied, seedlings can not absorb it, which will bring fertilizer damage, easy to burn roots and affect growth.Be careful not to apply it.
