Sunflowers are usually planted in spring, with March to April being the best planting time. When sowing, choose full, vigorous seeds to plant in the soil. The soil requirements must be loose and fertile, with good breathability and drainage. The plants grow best at temperatures above 18 degrees, with a daily sunlight duration of over 8 hours. The following introduces the planting time, soil preparation, sowing, seedling germination, and post-planting management.
1. Planting Time
There are no strict requirements for the planting time of sunflowers. It is best to plant in spring because the mild climate is suitable for plant growth and has a high survival rate.
2. Soil Preparation
Sunflowers need to grow in soil that is loose and fertile, with good breathability and drainage. Humus soil, garden soil, and sandy loam soil are all suitable. A small amount of organic fertilizer can be added to increase the organic nutrients in the soil.
3. Sowing and Planting
Choose full, vigorous seeds and spread them evenly in the soil. Maintain a temperature above 20 degrees and water sparingly, covering a thin layer of soil on top. Sunflower seeds will take root and sprout in a warm and humid environment.
4. Seedling Germination
After the sunflower seeds germinate, they need sufficient sunlight, with at least 8 hours of light exposure per 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 temperatures and place them in a shady location. In winter, when the temperature is low, it should not be below 5 degrees. It can be placed in a location with sufficient indoor lighting. Water every 2-3 days in spring and autumn, and water every 1-2 days in summer when water evaporates quickly. Use pesticides or carbendazim to spray them to prevent diseases and pest problems.
