Red, White, and Pink Cattleya Orchids: Care and Beauty

Provide bright, indirect light, similar to what they’d receive in their natural habitat under tree canopies.
An east-facing window is ideal, or a south-facing window with sheer curtains to filter the light.
Look for medium-green leaves as a sign of adequate light. Dark green leaves suggest insufficient light, while yellowing indicates too much.
2. Watering
Allow the potting medium to dry out slightly between waterings.
Water thoroughly, letting excess water drain away completely.
Use room-temperature, distilled, or rainwater to avoid mineral buildup.
3. Humidity
Maintain 50–70% humidity.
Use a humidifier, a pebble tray, or mist the plant occasionally to increase humidity.
Ensure good airflow to prevent fungal diseases.
4. Temperature
Daytime: 70°F–85°F (21°C–29°C).
Nighttime: 55°F–65°F (13°C–18°C).
A slight drop in nighttime temperature helps trigger blooming.
5. Potting Medium
Use a well-draining orchid mix, typically made of bark, charcoal, and perlite.
Repot every 2–3 years, preferably in spring after blooming.
6. Fertilizer
Feed with a balanced orchid fertilizer (20-20-20) diluted to half strength every 2–3 weeks during active growth.
Reduce feeding in the fall and winter when the orchid is resting.
7. Pruning and Maintenance
After blooms fade, trim the spent flower spike to encourage new growth.
Remove any yellow or damaged leaves at the base.
Encouraging Blooms
Ensure the orchid receives 12–14 hours of light daily.
Provide a cool temperature drop (10°F / 5°C lower at night) to encourage flower buds.
Do not over-fertilize; too much nitrogen can lead to lush foliage but no blooms.
