ðą How to Care for Coca plant to Prevent Sooty Mold?
ð§ How to Water
Water regularly to keep the substrate uniformly moist, but never waterlogged. Allow the surface layer to dry out slightly between waterings and reduce frequency during cooler periods. Overwatering promotes root rot.
âïļ Lighting
Place it in full sun; it does not grow well in shade. Indoors, it needs the brightest possible position or supplemental light, as lack of light weakens the foliage.
ðŠī Ideal Soil
Use a loose, loamy, organic-rich substrate with excellent drainage and a slightly acidic pH (5.5-6.5). You can mix garden soil with compost and draining material like perlite or coarse sand.
