🌱 How to Care for Stevia to Prevent Spider Mites?

Water regularly to keep the soil consistently moist, but never waterlogged – excess water in the root ball easily leads to root rot. Water at the base of the plant to keep the leaves dry.

Use light, well-draining soil rich in organic matter with a pH of 6.5–7.2. For heavier soils, mix in sand or perlite for better drainage.
