1、 Curing conditions

1. Soil: sunflower has no high requirements for soil because of its good growth ability. However, it is best to use soil with good drainage performance and humus, and it is best to apply some base fertilizer

2. Light: it must accept light in the process of growth and flowering. It is best to breed in the sunny place. If it's potted farming, you can move outdoors to bask in the sun

3. Temperature: it is not cold resistant. The temperature of breeding during the day should be adjusted at about 21-27 ℃, and the temperature at night should not be too low, but should be adjusted at 10-16 ℃. In addition, the temperature difference should not be too small, otherwise its stems and leaves may grow in vain

4. Moisture: pay attention to watering during maintenance. If it is short of water for a long time, its leaves may wither due to lack of water. During the growth period, you can replenish water once every 1-2 days, and you can water more when the temperature is high

2、 Breeding method

The method of sunflower propagation is sowing. The most suitable time is from March to April in spring. If the temperature is controlled at 18-25 ℃, it is the best. Before sowing, buy plump seeds and soak them in warm water before sowing. Prepare the soil for sowing, put the sharp end of the seed down, plant it in the soil and cover it with a layer of soil
