🌱 How to Care for Mendel's Cattleya to Prevent Scale Insects?

💧 How to Water

Water thoroughly every 7–12 days, allowing the potting medium to nearly dry out between waterings. Ensure excellent drainage — 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.

☀️ Lighting

Provide bright, indirect light of 21,000–50,000 lux (2,000–4,700 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.

🪴 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 (25–33%) to retain slight moisture. Avoid heavy, water-retaining mixes that promote root rot.
