When is the right time to sow sunflowers?

Sunflower planting time

Sunflower is a plant of the Asteraceae family and the Helianthus genus. Its inflorescence follows the sun, and for this reason it is also called sunflower.

Sunflowers can be planted twice a year. The best time to sow sunflowers is from March to April each year. The temperature at this time is just right for seed germination.

Sunflower sowing method

Before sowing sunflowers, you need to choose seeds with full grains, disinfect them in advance, and then plant them in loose soil. At this time, you can water them thoroughly once, keep the soil slightly moist, and keep them in semi-shaded place. They will germinate soon.

Key points for sunflower planting

1. Sunflower is suitable for growing in loose and fertile soil. You can mix peat, vermiculite and sand, and add a little organic fertilizer. If the temperature is low during planting, you can cover it with film to keep warm and shorten the germination time. You can transplant it when the plant grows a pair of true leaves.

2. Sunflowers are afraid of waterlogging, so water should be controlled appropriately to prevent the branches and leaves from growing too tall. You can water them appropriately according to the growth of the plants to meet their growth needs. In addition, you also need to weed and loosen the soil to break up the compaction so that the roots can better absorb nutrients and the growth will be accelerated.

Sunflower flowering time

Sunflowers can be sown in spring and summer, and flowers will appear 30 to 40 days after sowing. The main flowering period is from mid-July to mid-to-late August, and the flowering period lasts more than 15 days.
