Maintenance skills
First of all, light
Sunflower is a strong positive flower, which is sunny. When maintaining at home, be sure to give it enough light, even if it is exposed in summer, it doesn't need shelter. If there is a lack of light, it will affect the amount and size of sunflower flowers.
Second, the temperature
The most suitable growth temperature of sunflower is 26-29℃, and it is not afraid of high and low temperatures. The lower the temperature, the slower the growth rate of sunflower. When the temperature is lower than 15℃, the sunflower will stop growing.
Third, water.
Sunflowers like to grow in dry soil. They are afraid of drought and waterlogging. If they are watered too much, their roots will rot. Therefore, in the growing period of plants, water supply must be strictly in accordance with the principle of "seeing dry and seeing wet".
Fourth, fertilization.
Sunflowers don't need much fertilizer and water, so we only need to apply compound fertilizer once in the plant growth period to promote the growth of sunflowers, and apply phosphorus and potassium fertilizer once before the plants bloom to promote the flowering of sunflowers.
