Straw chrysanthemum can be sown and propagated in spring in April every year.
In spring, to make the straw chrysanthemum can contact enough light, but it needs some shade to avoid the bad growth of the plant due to high temperature and strong light.
In spring, straw chrysanthemum grows vigorously. We should pay attention to the large amount of water and fertilizer, but we should pay attention to the prevention of waterlogging in rainy days.
The suitable temperature for the growth of Stevia is 15-25 ℃, which is not heat-resistant. When the temperature is higher than 34 ℃ in summer, the growth of Stevia is obviously poor, and the light is strong in summer. Curing under direct light will make the leaves of Stevia become smaller, the plants grow in vain, and even the leaves fall off. Therefore, we should pay attention to shade in summer.
During the high temperature period in summer, Stevia rebaudiana often enters into dormancy state, which requires little fertilizer and water, and even needs to control fertilizer and water. The interval between watering in rainy days or in low temperature is longer or not. The watering time should be arranged in the morning when the temperature is low, and keep the leaves dry at night. Spray the plants regularly.
In order to avoid high temperature in summer, straw chrysanthemum is usually planted in autumn and winter.
In autumn, straw chrysanthemum also grows vigorously, but also pay attention to the interval between watering and fertilization. At the same time, pay attention to the shade in the weather with high temperature.
In winter, when the temperature is below 4 ℃, it will enter into dormancy or death. In winter, because the temperature is not very high, it should be given direct sunlight to facilitate its photosynthesis, flower bud formation, flowering and fruiting. And do a good job in fertilizer control and water control, and try to arrange the watering time in sunny days at noon when the temperature is high.
