2. How to raise sunflowers

Pot soil: if it is a potted sunflower, pay attention to choose a larger pot. The weak acid soil with good drainage and rich humus should be selected as the soil, so that the basin soil conditions will be more suitable for its growth

Watering: sunflower itself is relatively heat-resistant, but its demand for water is relatively strong, because it consumes a lot of water. Sunflower plant is tall and has many leaves, so we should pay attention to replenishing water in time in daily maintenance. Increase the frequency of watering and the amount of watering appropriately, and do not let the soil dry. But it doesn't need too much water before it appears. After it appears, it will have a greater demand for water

Temperature: in the process of cultivating sunflower, the temperature of its growth environment should not be less than 10 degrees. Only in a warm environment can it grow faster. The temperature needs to be between 21 and 27 degrees Celsius during the day and between 10 and 16 degrees Celsius at night

Light: sunflower grows in the sun, and light is an essential condition for its vigorous growth. Therefore, it must be ensured that it can receive sufficient light every day, at least about ten hours of light every day
