🌱 How to Care for Rainbow Bush to Prevent Spider Mites?

💧 How to Water

Water deeply, then let the soil dry out completely before watering again, roughly every two weeks during the growing season and much less in winter. Because the cream sections lack chlorophyll, overwatering causes rot faster than in the all-green species.

☀️ Lighting

Place in bright light with a few hours of direct or filtered sun daily. Low light causes the stems to stretch and the leaves to lose their pink and cream tones.

🪴 Ideal Soil

Use a well-draining cactus or succulent mix, ideally amended with extra perlite or coarse sand so water never pools around the roots.
