Stevia cultivation methods and precautions

1. Maintenance methods

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

2. Light: It is sensitive to light and can be placed in a place with good light during maintenance. The lighting time does not need to be too long, 2-3 hours of lighting a day is enough.

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 resistance 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 growing period, and then apply it again after it matures. During the growing period, more fertilizer can be applied to ensure that it has the nutrients it needs for growth.

2. Breeding techniques

1. Transplanting: It is best to transplant in May or June when the temperature is around 15°C. The survival rate is also relatively high. There is no problem as long as there is no late frost.

2. Reproduction: Sowing is the most common way to propagate stevia. The soil should be wetted with water before sowing. After sowing, cover the seeds with a thin layer of soil, spray water to keep them moist, and wait for them to germinate.

3. Problem diagnosis and treatment

1. Bridge-building insects: The main harm is to eat the leaves of the plants. After discovering the bridge-building insects, you can use a 1000-fold diluted solution of 40% omethoate to spray. It will be effective after using it several times.

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

IV. Other issues

1. Is it edible? Stevia is edible, and its leaves can be eaten directly. After washing, 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 grow well indoors.
