How to grow sunflowers?

First, planting time

It can be planted in spring, summer and autumn, mostly in spring. If it is in the south, it can be planted in mid-April. If it is in the south or the north, the time can be adjusted appropriately, as long as the average temperature is around 18 degrees.

Second, the planting method

1, sowing

Spread the seeds evenly in the soil, keep the temperature above 20 degrees, and germinate in about 10 days.

2, seedling planting

When the seedlings grow to a certain height, they can be planted alone. If you want to cultivate in soil, you don't need to bring soil when planting alone, and you don't need to water it often during the growing period. And control the row spacing of plants, and apply liquid fertilizer many times during this period. In addition, remember to harvest the seeds in time when the fruit is about to crack, otherwise it will be scattered all over the floor. If it is potted, it is planted in the same way as soil culture.

water

Watering depends on the soil conditions in the basin. Generally, if it is not dry, there is no need to water it. If you water it, water it thoroughly at once.

4, correct fertilization

It doesn't need too much fertilizer, just apply potassium dihydrogen phosphate once every half month, which will make its flowers big and bright and the flowering period will be longer.

5. Lighting equipment

It likes sunny places very much, so it must get more sunshine when it grows, so that it can thrive.

6. Temperature

It likes warm places, and the optimum temperature for germination is 2 1 to 24 degrees, so that seedlings can grow in a week or so.
