How to plant sunflowers in pots? Cultivation and breeding methods of sunflowers

Sunflowers are usually planted in spring, with March and April being the best planting time. When sowing and planting, choose seeds with full growth and sow them into the soil. The ambient temperature should be controlled above 18 degrees and the light time should be maintained at more than 8 hours a day, so that they can grow healthily.

How to grow sunflowers

1. Planting time

  There is no strict planting time for sunflowers. They are usually planted in the spring of each year, specifically in March and April, because the climate is mild at this time, suitable for plant growth and with a high survival rate.

2. Prepare the soil

  Sunflowers need loose, fertile, air-permeable and well-drained soil, such as humus soil, garden soil and sandy river soil. A small amount of organic fertilizer can be added to increase the organic nutrients in the soil.

3. Seeding and planting

  Choose plump seeds that are growing well, spread them evenly in the soil, keep the temperature above 20 degrees, water them in small amounts, and cover them with a thin layer of soil. They will soon take root and sprout.

4. Cultivate germination

  After germination, sunflower seeds need sufficient light time, at least 8 hours of light time a day, and the temperature should be above 20 degrees. After 7-10 days, use diluted nitrogen, phosphorus and potassium compound fertilizer and water once every 2-3 days.

Points to note when planting sunflowers

1. The seeds of sunflowers are relatively small. It is best to sow them in fine sandy soil without weeds and stones. The ambient temperature should be controlled between 20 and 25 degrees. Generally, they will germinate 10 days after sowing. If the seedlings are crowded, you can thin them out.

2. When the sunflower grows up, it needs to be provided with sufficient light. The more sunlight it gets, the more vigorously it will bloom. If it is placed in a dim, humid, and unventilated place, it will grow tall and thin, bloom very few flowers, and cannot be grown well. Therefore, it needs sufficient light to promote its growth.

3. The more you water the sunflower, the faster it grows. Normally, it only needs a little moisture in the soil. The temperature is relatively high in summer and the water evaporates quickly. You should water it in time when the soil is dry. However, you must control the amount of water to avoid water accumulation in the soil, which will cause the roots of the sunflower to rot.
