Temperature: Stevia grows best in an environment of 20-30℃, and can withstand low temperatures as low as -5℃. Light: It does not require much light, and a short period of light every day can satisfy it, about 2-3 hours. Watering: It likes a moist growing environment, and it is best to keep the soil moist. Fertilizer: Apply top-dressing fertilizer once each during the seedling, growth and maturity stages. Do not apply too much during the seedling stage.

1. Maintenance methods

1. Temperature: Stevia has a certain ability to withstand low temperatures and can survive at temperatures of -5°C. The optimal temperature is between 20-30℃, so there is no need to worry about it in winter.

2. Lighting: It is relatively sensitive to light, so it can be placed in a place with good light during maintenance. The lighting time does not need to be too long, just 2-3 hours of lighting every day.

3. Watering: It likes to grow in places with high humidity. During the breeding period, the soil should be kept slightly moist, because its drought tolerance is relatively poor, and it will appear listless if it lacks water. .

4. Fertilizer: After the seedlings survive, fertilizer needs to be applied once. Apply fertilizer once during its growth period, and then again when it matures. During the growth period, you can add a little more fertilizer to ensure the nutrients it needs for growth.

2. Breeding skills

1. Transplanting: Transplanting is best done in May-June, when the temperature is around 15℃, and the survival rate is also relatively good. It's high, as long as you do it when there's no night cream, there's no problem.

2. Propagation: Sowing is the most common way of propagating stevia. Before sowing, the soil should be moistened with water. After sowing, cover the seeds with a thin layer of soil, spray water to moisturize and wait for germination.

3. Problem Diagnosis and Treatment

1. Bridge-forming insects: The main harm is eating the leaves of plants. After discovering bridge-forming insects, you can use 40% omethoate diluted 1000 times Spray the liquid and it will be effective after using it a few times.

2. Leaf spot: This is a common disease, mainly caused by poor environmental ventilation. After getting sick, you should spray carbendazim in time, once every half month, and the effect will be effective soon.

IV. Other questions

1. Can it be eaten: Stevia is edible, and its leaves can be eaten directly. After cleaning, you can use it to soak in water or cook porridge. It tastes particularly sweet.

2. Can it be grown indoors: It can be grown indoors because it requires less light. As long as you pay attention to ventilation, it will also grow well indoors.
