What are the cultivation methods and precautions for sunflowers

Sunflowers are suitable for planting in fertile, loose soil with good drainage. During the growing period, they need to ensure sufficient sunlight exposure to become lush and leafy. However, in the hot summer, shading measures need to be taken. Also, it is necessary to check the bottom cover of the flower pot frequently, check the ventilation of the flower pot, water every day if the ventilation is good, and water every two days if the ventilation is general. Fertilize frequently during the growing season, preferably every two weeks.

Cultivation methods for sunflowers

Sunflowers are plants of the Portulaca family, a hybrid of Portulaca grandiflora and Portulaca oleracea. The common propagation methods for sunflowers include sowing, dividing, and cutting.

Sunflowers are easy to grow and have a wide adaptability to soil. Choose fertile and loose soil, and ensure sufficient sunlight exposure during the growing period to become lush and leafy.

However, in the hot summer, shading measures need to be taken. Also, it is necessary to check the bottom cover of the flower pot frequently, check the ventilation of the flower pot, water every day if the ventilation is good, and water every two days if the ventilation is general.

Watering method

After sowing sunflowers in spring, it is important to control water and try to use the spray method to replenish water. Summer is a period of rapid growth, so it's best to water once a day. In autumn, water every 2-3 days, and in winter, water every half month to keep the soil slightly on the dry side.

Fertilizing method

Although sunflowers can tolerate poor soil, it is still recommended to fertilize during growth for a more vigorous growth and longer flowering period. The specific fertilizer to use depends on the growth stage. Seedlings do not need to be fertilized. After germination, more phosphorus fertilizer is needed, so potassium dihydrogen phosphate should be applied every two weeks. Before flowering, there is a high demand for phosphorus and potassium fertilizers, so they should be replenished in a timely manner.

Pruning method

Sunflowers grow quickly and need to be pruned during the seedling stage, mainly by pinching. This should be done when 8 to 10 leaves have grown, by cutting off the top of the main stem. During the growing period, dense, vigorous, weak, and crossed branches should be pruned, as well as leaves, to improve ventilation, enhance light penetration, and save a lot of nutrients, promoting more flowering.

Precautions for sunflower cultivation

1. Sunflowers have high water requirements during their growing period and cannot be short of water. Usually, water every other day, but do not let water accumulate.

2. Sunflowers like the sun and should be placed in a bright area. Sufficient light is necessary for better growth. Insufficient light makes it difficult for them to bloom. Fertilize frequently during the growing season, preferably every two weeks. They have a certain tolerance for poor soil, but the plants will grow better if the soil has good drainage and is fertile.
