How to grow Roselle in spring

1. Control Lighting

Roselle does not require much light, even in spring, it still does not need too much light. The daily lighting time cannot exceed five hours. After the light exposure reaches the standard, it needs to be placed in a semi-shaded environment for growth. Too much light will affect its flowering time. The sun in early spring is not very strong, and it can receive normal sunlight in the morning and afternoon. At noon, it needs to be moved to a cool place.

2. Adjust humidity

It is not suitable to grow in a hot and humid environment, and the humidity requirement for the growing environment is dry. If it grows in a relatively humid place, it is easy to get sick. On the contrary, it will grow better in a dry environment. The climate in spring is changeable. If the humidity is too high, it needs to be kept in a dry and ventilated place.

3. Control the temperature

The plant has relatively high requirements for temperature. If the temperature is lower than 15 degrees and higher than 25 degrees, its growth will be affected. It is enough to control the growth temperature at 20 degrees. The temperature in early spring is unstable and spring cold often occurs, so try to avoid open-field planting. Open-field planting can only be carried out after the climate stabilizes.

4. Increase nutrients

It does not require much nutrients, and generally fertile soil can meet its needs. If the land is too barren, it is necessary to fertilize the soil twice a month, mainly with thin fertilizers, such as farmyard manure, compost and other fertilizers.
