🌱 How to Care for Snow Bush to Prevent Leaf Spot?

💧 How to Water

Water as soon as the top inch of soil feels dry, roughly every 2-3 days in warm weather. Snow bush wilts fast when thirsty, so do not let it dry out completely, but avoid waterlogging the roots.

☀️ Lighting

Place in bright, indirect light or morning sun — a spot within a foot of a south-facing window is ideal indoors. Too little light causes the leaves to lose their white and pink variegation and revert to solid green.

🪴 Ideal Soil

Use a fertile, well-draining mix (potting soil, peat and perlite in roughly a 2:1:1 ratio) with a slightly acidic to neutral pH of 6.0-7.0. Good drainage is essential to avoid root rot.
