1、 How to raise sunflowers

1. Suitable soil: sunflower has low requirements for soil, and general soil can be planted. But if you want sunflowers to grow better, you'd better choose weak acid or neutral soil with good drainage performance and humus

2. Proper watering: it can resist heat, but it also belongs to plants that consume more water. The plant is tall, with many and dense leaves, and the water absorption is 1.74 times that of corn. Therefore, in daily maintenance, if you see that the soil is dry, you need to supplement water in time. Different growth stages have different requirements for water. From sowing to budding, the demand for water is low, from budding to flowering is the peak of water demand, and there is also more water demand from flowering to maturity

3. Suitable temperature: in the whole growth process, as long as the temperature is not lower than 10 ℃, its growth will not have much problem. The temperature should be about 21-27 ℃ during the day and about 10-16 ℃ at night. In the appropriate temperature range, the higher the temperature, the faster it develops

4. Sufficient light: sunflower is a plant with short sunshine, and its response to sunshine is not very sensitive. It is necessary to receive sufficient light to ensure at least 10 hours of sunshine every day, which is conducive to the growth of sunflowers

2、 When will sunflowers be planted

Sunflower sowing time is generally from March to April, and the suitable sowing temperature is 18-25 ℃. It is usually planted after the temperature rises to 20 degrees, and the seeds will begin to germinate in about 10-15 days. When planting sunflowers in pots, try to choose a larger flower pot, and then choose weak acid or neutral soil with good drainage performance and humus. Place 2-3 seeds at a depth of about 2cm in the middle of the pot. After sowing, it should be watered with water, and then placed in a warm and ventilated place to germinate
