ðą How to Care for Mendel's Cattleya to Prevent Grey Mould?
ð§ How to Water
Water thoroughly every 7â12 days, allowing the potting medium to nearly dry out between waterings. Ensure excellent drainage â never let roots sit in standing water. Reduce watering frequency in winter during the rest period. Mounted specimens may be watered more frequently as they dry faster.
âïļ Lighting
Provide bright, indirect light of 21,000â50,000 lux (2,000â4,700 footcandles). A south- or east-facing window with a sheer curtain works well indoors. Avoid direct midday sun which can cause leaf scorch. Good light is essential for reliable flowering.
ðŠī Ideal Soil
Use a well-draining orchid medium: coarse bark chips, tree fern fiber, or cork mounts are ideal. The medium should dry quickly between waterings. Sphagnum moss can be added (25â33%) to retain slight moisture. Avoid heavy, water-retaining mixes that promote root rot.
