How to grow sunflowers to make them bloom
This article focuses on the green plant care tips for how to grow sunflowers to make them bloom and explanations of sunflower planting methods. Let's take a look together.
Sunflowers are usually planted in spring, with March to April being the best planting time. When sowing, select plump seeds and plant them in the soil. The soil requirements must be loose and fertile, with good aeration and drainage. The plants grow best at temperatures above 18 degrees, with more than 8 hours of sunlight daily. The following introduces the planting time, soil preparation, sowing, seedling germination, and post-planting management, among other aspects.
1. Planting Time
There are no strict requirements for the planting time of sunflowers. It is best to plant them in spring because the mild climate is suitable for plant growth and has a high survival rate.
2. Soil Preparation
Sunflowers require soil that is loose, fertile, well-aerated, and has good drainage. Humus soil, garden soil, and sandy soil are all suitable. A small amount of organic fertilizer can be added to increase the soil's organic nutrients.
3. Sowing
Select seeds with good growth and fullness, and scatter them evenly in the soil. Maintain a temperature above 20 degrees and water sparingly, covering them with a thin layer of soil. Sunflower seeds will take root and germinate in a warm and humid environment.
4. Germination
After sunflower seeds germinate, they need ample sunlight, at least 8 hours a day. Keep the temperature above 20 degrees, and use diluted nitrogen-phosphorus-potassium compound fertilizer after 7-10 days. Water every 2-3 days.
5. Post-Planting Management
After planting sunflowers, they require careful management. In spring and autumn, when the temperature is stable, and in summer, when the temperature is high, avoid high heat and place them in a shady location. In winter, when the temperature is low, it should not be below 5 degrees. They can be placed in a well-lit indoor position. Water every 2-3 days in spring and autumn, and 1-2 days in summer when water evaporates quickly. Use insecticides or carbendazim to spray them to prevent diseases and pest problems.
