Key Points for Sunflower Care
Do you know these? Here are some experiences with the herbaceous flower sunflower, the key points for sunflower care, followed by detailed content sharing.
Sunflowers are generally propagated by seeds, and they also have a strong self-sowing ability. However, with the emergence of a large number of new horticultural varieties, their seeds are difficult to collect. Especially the double-petaled new horticultural varieties, which do not produce seeds after flowering. Therefore, family propagation can use the cutting method.
1. Overwintering Seedlings: After the Frost Descending solar term each year (in the Shanghai area), move the double-petaled sunflowers to a sunny indoor location. After winter begins, place them on the inner side of a glass window, allowing the potting soil to be slightly dry to ensure safe overwintering. After Qingming the following year, the pot can be placed outside the window. If a cold wave hits, it still needs to be moved inside for care.
2. Cutting Time: From early May to the end of August, you can cut 5cm long tender stem tips for propagation by cutting.
3. Preparing Potting Soil: Use 3 parts of mature garden soil, 5 parts of yellow sand, 2 parts of rice husk ash or fine sawdust, and a little superphosphate powder, mix them evenly to make the potting soil.
4. Planting Containers: Clay pots, ceramic pots, plastic flower pots, or other containers with bottom drainage. Place a piece of tile at the bottom drainage area to facilitate drainage, and then you can fill it with potting soil for planting.
5. Cutting Method: Flatten the surface of the potting soil in the container, insert the cut sunflower tender stems into the holes made by a bamboo chopstick, with the depth not exceeding 2 centimeters into the potting soil. To make the pot plant form and become lush quickly, depending on the size of the pot, as long as there is a 2 cm spacing, you can plant multiple cuttings (when the seedlings become crowded, they can be transplanted to other pots). Then water thoroughly. The newly cut seedlings can be shaded or not shaded; as long as there is some humidity, they generally can survive within 10 to 15 days and enter normal care.
6. Regular Care: Sunflowers have very few diseases and pests. Maintaining some moisture and applying a thousandth of potassium dihydrogen phosphate every half month can achieve the goal of large flowers with bright colors and continuous blooming. If multiple varieties are planted in one pot, with various flowers blooming together, the ornamental value is even higher.
