ðą How to Care for Lady Slipper Orchid to Prevent Scale Insects?
ð§ How to Water
Water thoroughly when the top inch of the potting medium feels dry, typically once a week. Use tepid water and avoid wetting the crown, as standing water in the leaf axils can cause bacterial rot. Reduce watering slightly in winter.
âïļ Lighting
Provide bright, indirect light (800-1000 foot-candles). East or west-facing windows are ideal. Avoid direct sunlight, which can burn the leaves. The plain green leaves indicate this is a cool-growing type that tolerates lower light than mottled-leaf varieties.
ðŠī Ideal Soil
Use a well-draining orchid mix of fine-grade fir bark, perlite, and sphagnum moss. The medium should retain some moisture while allowing air to reach the roots. Repot every 2 years or when the medium starts to decompose.
