What kind of fertilizer does sunflower like? How to fertilize sunflower

1. Fertilization method

Although it is tolerant to poor soil quality, it still needs to be fertilized if you want it to grow more vigorously and have a longer flowering period. The specific fertilizer you prefer should be determined according to the growing season. No fertilizer is needed during the seedling stage. After germination, the demand for phosphorus fertilizer will be high. A small amount of potassium dihydrogen phosphate fertilizer can be applied. It is recommended to dilute it and apply it once every two weeks so that it is easier to absorb. In addition, more nutrients are consumed during the flowering period, so phosphorus fertilizer and potassium fertilizer should be supplemented to make the flowers more colorful and the flowering period longer.

2. Environmental requirements

1. Temperature: It likes a temperature environment between 20-30 degrees. Although it has strong adaptability, it is not cold-resistant. It must be moved indoors as soon as possible after the temperature drops, and the temperature must be controlled above 10 degrees to survive the winter, otherwise it will be frozen to death.

2. Watering: It is very drought-resistant and does not need to be watered too frequently. Just water once every one or two days during the growing season. After flowering, the roots should be watered in time, and watered once a day. The fruits will be fuller with sufficient water.

3. Light: As its name suggests, it loves light very much. It will only bloom when there is enough light. If it is rainy, the flowers will be closed due to lack of light. Therefore, it should be placed in a bright place and exposed to the sun as much as possible. It is best to give it light all day so that it can bloom normally and grow vigorously.
