Sunflower sowing should be done when the temperature is relatively stable and the temperature is relatively suitable, usually around April is more appropriate.When the temperature rises above 20 degrees, it can be ready to start planting, and the seeds will germinate in 10 to 15 days after planting.Its growth rate is very fast, the growth cycle is relatively short, generally sowing in spring, the summer of that year can blossom.
Pot soil: If it is a potted sunflower, pay attention to choose a larger pot.The soil should be slightly acidic soil with good drainage and rich humus, so that the pot 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 plants are tall and have more leaves, so we should pay attention to timely replenishment of water in daily maintenance.Increase the frequency of watering and increase the amount of watering appropriately, do not let the soil dry.But it doesn't need to be watered too much before it comes into bud, and it will need more water after it comes into bud.
Temperature: In the process of cultivating sunflower, it is necessary to ensure that the temperature of its growth environment cannot be lower than 10 degrees.Only in warm environment, its growth rate will be faster.The temperature needs to be between twenty-one and twenty-seven degrees Celsius during the day and between ten and sixteen degrees Celsius at night.
