🌱 How to Care for Chinese Fringe Flower to Prevent Leaf Spot?
💧 How to Water
Keep the substrate moist but never waterlogged: water every 2-3 days in summer and weekly in winter, allowing the top layer of soil to dry slightly between waterings. Excess water promotes root rot.
☀️ Lighting
Prefers full sun to partial shade. With more direct light, the foliage develops more intense purple or burgundy tones; in excessive shade, the leaves tend to turn green and flowering decreases.
🪴 Ideal Soil
Requires an acidic substrate (pH 5.5-6.5) and well-drained soil, similar to that of camellias or azaleas. In alkaline soils, it may suffer from chlorosis (yellowing of leaves); if this is the case, add ericaceous soil or fertilizer for acidophilic plants.
