Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily. Direct morning sun is tolerated; avoid harsh afternoon sun, especially in summer.
Sunlight Tolerance Tips:
Acclimate plants gradually to increased light; protect from intense midday sun; provide shade or filtered light during peak summer hours.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even light exposure; use sheer curtains to diffuse strong sunlight; avoid placing near south-facing windows in summer.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until water drains from the bottom; allow the medium to dry partially between waterings; avoid waterlogging.
Soil
well-draining orchid mix with bark and perlite
pH: Slightly acidic (pH 5.5–6.5).
Use orchid-specific mix; avoid heavy potting soils; ensure pots have drainage holes.
Temperature
Prefers 18–30°C (64–86°F). Tolerates cooler nights down to 10°C (50°F) but avoid prolonged exposure below 10°C.
Avoid sudden temperature fluctuations; protect from frost; maintain consistent night temperatures above 10°C.
Fertilizing
every 2 weeks during active growth with balanced orchid fertilizer, every 3 months in winter
Flush pots with plain water monthly to prevent salt buildup; fertilize after watering to avoid root burn.
Propagation
Methods
Stem cuttings (keikis) or division of pseudobulbs.
Step-by-Step Propagation Guide
- Select a healthy stem.
- Cut below a node.
- Apply rooting hormone if used.
- Place in medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (22–28°C), and indirect light.
Medium
Fine orchid bark mix or sphagnum moss with perlite for drainage.
Hormone
Rooting hormone is optional but can speed up root development.
Timeline
Roots may develop in 4–8 weeks; establishment takes 3–6 months.
Tools Needed
Sharp scissors, rooting hormone, propagation tray, humidity dome.
Quick Tips
Keep cuttings moist but not waterlogged; provide bottom heat for faster rooting; avoid direct sunlight.
Pruning & Repotting
Pruning Guide
Method
Cut canes at the base with clean, sharp tools; avoid cutting into healthy growth.
Pruning Plan
Focus on removing dead or damaged canes to encourage new growth and flowering.
Tools
Pruning shears, sterilizing solution (70% alcohol).
Checklist
Sterilize tools; cut dead canes; avoid over-pruning; clean debris.
Repotting Guide
Best Season
Spring, after flowering, when new growth begins.
Pot Size
Increase pot size by 2–3 cm (1–1.5 inches) in diameter.
Method
Remove old medium; trim dead roots; place in a slightly larger pot with fresh orchid mix; ensure good drainage.
Suggestions
Repot every 2–3 years or when the potting medium decomposes or the plant outgrows its container.
Checklist
Prepare new pot; trim roots; use fresh medium; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check medium moisture; water thoroughly; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water directly onto the potting medium, ensuring even moisture distribution. Water early in the day to allow foliage to dry. Ensure excess water drains completely to prevent root rot.
Watering Schedule Tips
Water every 7–10 days during active growth, reducing frequency to every 2–3 weeks in winter. Adjust based on humidity, temperature, and potting medium dryness.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate sphagnum moss for moisture retention.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis, leaf drop, bud abortion, or stunted growth indicate temperature stress.
Cold Stress
Low temperatures slow metabolic processes, leading to root damage and reduced nutrient uptake.
Solution: Move to a warmer location; insulate pots; avoid cold drafts; reduce watering in cooler conditions.
Hot Stress
Excessive heat causes dehydration, wilting, and scorched leaves, especially with inadequate humidity.
Solution: Provide shade; increase humidity through misting or a humidifier; ensure adequate ventilation; water more frequently if heat is prolonged.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during growing season; flush periodically.
Fertilizing Method
Use a balanced orchid fertilizer (20-20-20) diluted to half strength every 2–4 weeks during active growth. Reduce or stop fertilizing in winter.
