How to Plant Sunflowers
If you want to learn how to plant sunflowers and the key points of sunflower cultivation techniques, the following article will share detailed information.
Sunflowers are usually planted in spring, with March to April being the best planting time. When sowing, select full-grown seeds and plant them in the soil. The soil should be loose and fertile, with good ventilation and drainage. The plants grow best at temperatures above 18 degrees Celsius, and the lighting time should be maintained at 8 hours per day or more. The following introduces planting time, soil preparation, sowing, seed germination, and post-planting management.
1. Planting Time
There are no strict requirements for sunflower planting time, but it is best to plant in spring. This is because the spring climate is mild, suitable for plant growth, and has a high survival rate.
2. Soil Preparation
Sunflowers require soil that is loose, fertile, with good ventilation 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 soil's organic nutrients.
3. Sowing and Planting
Select full-grown seeds with good growth and evenly scatter them in the soil. Maintain a temperature above 20 degrees Celsius, water sparingly, and cover with a thin layer of soil. Sunflower seeds will root and sprout in a warm and moist environment.
4. Seed Germination
After sunflower seeds germinate, they need plenty of sunlight, at least 8 hours a day. Keep the temperature above 20 degrees Celsius 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 temperatures are stable, avoid high temperatures in summer by placing them in a shaded area for cultivation. In winter, when temperatures are low, they should not be below 5 degrees Celsius. They can be placed in a well-lit indoor area. Water every 2-3 days in spring and autumn, and 1-2 days in summer due to rapid water evaporation. Use insecticides or carbendazim to spray them to prevent diseases and pest problems.
