Cultivation methods and precautions of sunflower

1. Maintenance methods

1. Substrate selection: Sunflower does not have too many strict requirements on the soil, so you don’t need to be too concerned about the choice of soil, but the best is loam with good drainage and fertile soil.

2. Light management: Sunflower likes a warm environment and requires sufficient light. It likes sunny and ventilated places, has strict requirements on light, and does not like shady environments.

3. Temperature management: It likes warmth and fears cold. The most suitable temperature for sunflower is 25-30℃. Temperatures below 15℃ will affect flowering and fruiting. When the temperature is below 14℃, the growth will become very slow, so the breeding temperature must be controlled.

4. Water management: It likes dry and humid environments, but does not like waterlogging. Too much drought can easily cause the plants to grow weak, and too much moisture can cause damping-off disease, so the soil should be kept moist.

2. Breeding techniques

In winter, the outdoor temperature is difficult to reach, so you should move indoors. Do not water too much at this time, otherwise it will easily cause waterlogging, which is not conducive to its wintering.
