When to Sow Sunflowers? A Detailed Guide to Sowing Time
Sunflowers can be sown in spring, summer and autumn, but because the climates of the north and south differ greatly, the south mostly sows in mid-April, while the north sows when the average temperature is around 18 degrees.Seedlings emerge 5 to 7 days after sowing. When sowing, choose a nutrient soil made by mixing loose, fertile and well-aerated sandy loam with compost soil, then scatter the seeds evenly over the soil, cover with a thin layer of soil, and place in a bright spot.
How to grow sunflowers:
1. Sowing
Scatter the seeds evenly in the soil and keep the temperature above 20 degrees; they will sprout in about 10 days.
2. Transplanting the seedlings
When the seedlings have grown to a certain height, they can be transplanted. If you want to grow them in soil, the plants do not need to be transplanted with soil attached, and they do not need frequent watering during the growing period. Also control the spacing between plants, apply liquid fertilizer several times during this period, and remember that when the fruit is about to split open, the seeds need to be harvested in time, otherwise they will scatter. If growing in pots, the transplanting method is the same as for soil cultivation.
3. Watering
Water according to the condition of the potting soil; generally, if it is not dry, there is no need to water, and when you do water, water thoroughly in one go.
4. Fertilizing correctly
It does not have high fertilizer requirements; applying potassium dihydrogen phosphate once every half month is enough, which will make its flowers larger and more vivid and also lengthen the flowering period.
5. Light
It loves places with plenty of sunlight, so while it is growing it must get plenty of sun, which is what allows it to grow lush and full of leaves.
6. Temperature
It likes warm places; the best temperature for germination is 21 to 24 degrees, at which seedlings will grow in about a week.
