How to maintain the newly sprouted sun flower seedlings?

Sunflowers originated in Brazil in South America and like warmth and sunshine. Planting in spring and autumn when the temperature is about 65438 08℃. When the temperature is controlled at 2 1 ~ 24℃, it can germinate. After about a week, seedlings grow on the buds. With the gradual increase of temperature, the seedlings grow up and grow vigorously.

Although sunflowers like warmth and sunshine, in hot summer, we should always check the bottom cover of Huapeng to check the air permeability of flowerpots. If the air permeability is good, water it every day, and if the air permeability is average, water it every other day.

Sunflower has strong vitality, and there is no pest problem. When planting, it is only necessary to carry out preventive spraying before germination to ensure pests such as aphids, apricot bees and apricot cones.

Fertilize soil or land

Sunflowers don't need much fertilization, so make sure to fertilize them once every two weeks and put them in sunny places every day, and they will have colorful beauty.

In autumn, we should focus on applying a little potassium fertilizer to the continuous cropping sunflower to make the root system stronger and more resistant to stress. Because the content of potassium in plants is very high, second only to nitrogen, it can not only prevent sunflower from lodging, but also greatly improve its drought and cold resistance, which is very important for wintering.

To supplement potassium to sunflower, you can directly use ready-made potassium fertilizer, not much at a time, just a few grains, and then pour it after dissolution, once every fifteen days, three times in a row. You can also soak some plant ash and water the sunflower with supernatant, which is safer.
