When is the Best Time to Sow Sunflowers
Answering netizens' questions about the best time to sow sunflowers and sharing some small experiences in green plant maintenance regarding sunflower sowing methods and timing. 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 must be loose and fertile, with good ventilation and drainage. The plants thrive best at temperatures above 18 degrees and require at least 8 hours of sunlight daily. The following sections introduce planting time, soil preparation, sowing, seed germination, and post-planting management.
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 results in a high survival rate.
2. Soil Preparation
Sunflowers require soil that is loose, fertile, well-ventilated, and has good drainage. Humus soil, garden soil, and sandy loam are all suitable. A small amount of organic fertilizer can be added to increase the soil's organic nutrients.
3. Sowing
Select healthy and plump seeds and scatter them evenly in the soil. Maintain a temperature above 20 degrees, water sparingly, and cover with a thin layer of soil. Sunflower seeds will root and germinate in a warm and moist environment.
4. Seed Germination
After sunflower seeds germinate, they need ample sunlight, at least 8 hours daily. 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 temperatures are stable, and in summer, when temperatures are high, they should be placed in a cool location to avoid extreme heat. In winter, when temperatures are low, they should not be below 5 degrees. They can be placed in a well-lit indoor location. Water every 2-3 days in spring and autumn, and every 1-2 days in summer due to rapid water evaporation. Use pesticides or carbendazim to spray them to prevent pest and disease problems.
