How long does it take for sunflowers to bloom after planting

Do you know these? Here are some small experiences about how long it takes for sunflowers to bloom and the planting, care, and management of sunflowers. Let's find out together.

Sunflowers are usually planted in spring, with March to April being the best planting time. When播种 planting, choose plump seeds and plant them in the soil. The soil must be loose and fertile, with good breathability and drainage. The plants grow best at temperatures above 18 degrees and require at least 8 hours of sunlight per day. The following introduces the planting time, soil preparation,播种 planting, 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 use soil that is loose, fertile, breathable, and has good drainage. Humus soil, garden soil, and sandy river soil are all suitable. A small amount of organic fertilizer can be added to increase the soil's organic nutrients.

3. Seed Planting

Choose plump seeds with good growth 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 take root and sprout in a warm and humid environment.

4. Seedling Germination

After sunflower seeds germinate, they need sufficient sunlight, at least 8 hours a day. Keep the temperature above 20 degrees and use diluted nitrogen, phosphorus, and potassium compound fertilizer after 7-10 days. Water every 2-3 days.

5. Post-Planting Management

After planting sunflowers, they need careful management. In spring and autumn, when the temperature is stable, and in summer, when the temperature is high, they should be kept out of the hot weather and placed 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 plenty of indoor light. Water every 2-3 days in spring and autumn, and every 1-2 days in summer when water evaporates quickly. Use pesticides or carbendazim to spray them to prevent diseases and pest problems.
