Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily. Direct morning sun is tolerated, but avoid harsh afternoon sun, especially in summer.
Sunlight Tolerance Tips:
Gradually acclimate to brighter light to prevent scorching. Indoors, place near an east-facing window. Outdoors, provide dappled shade during peak sun hours.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid direct afternoon sun.
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, and avoid waterlogging.
Soil
well-draining orchid mix with bark and perlite
pH: Slightly acidic to neutral (pH 5.5–6.5).
Use orchid-specific mix; ensure pots have drainage holes; avoid heavy potting soils.
Temperature
Prefers 18–27°C (64–80°F). Tolerates cooler nights down to 10°C (50°F) but avoid prolonged exposure below 5°C (41°F).
Avoid drafty areas; maintain stable temperatures; protect from sudden drops.
Fertilizing
every 2 weeks during active growth with balanced orchid fertilizer, none in winter
Flush roots with plain water monthly to prevent salt buildup; fertilize after watering to avoid burning roots.
Propagation
Methods
Stem cuttings (keikis) or division of mature pseudobulbs.
Step-by-Step Propagation Guide
- Select healthy pseudobulbs.
- Cut below a node.
- Apply rooting hormone.
- Place in medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (21–27°C), and indirect light.
Medium
Fine orchid bark mix or sphagnum moss with perlite for aeration.
Hormone
Optional, but rooting hormone can speed up the process.
Timeline
Roots may form 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.
Pruning & Repotting
Pruning Guide
Method
Cut pseudobulbs at the base with clean, sharp tools; trim flower spikes just above the node if keikis form.
Pruning Plan
Remove spent flower spikes and dead or damaged pseudobulbs to redirect energy to new growth.
Tools
Sterilized pruning shears, sharp knife.
Checklist
Sterilize tools; cut cleanly; remove debris; disinfect wounds if necessary.
Repotting Guide
Best Season
Spring, after flowering, when new growth begins.
Pot Size
Increase pot size by 2–5 cm (1–2 inches) in diameter.
Method
Remove old medium, trim dead roots, place in a slightly larger pot with fresh orchid mix, and ensure good drainage.
Suggestions
Repot every 2–3 years or when the medium decomposes or roots outgrow the pot.
Checklist
Prepare new pot; trim roots; use fresh medium; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check root moisture before watering; water thoroughly; ensure drainage; adjust seasonally.
How to Apply Water Properly
Water directly onto the root zone, ensuring even moisture distribution. Water early in the day to allow foliage to dry. Ensure excess water drains freely to prevent root rot.
Watering Schedule Tips
Water every 7–10 days during active growth (spring/summer), reducing frequency to every 2–3 weeks in winter. Adjust based on humidity and temperature.
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 blast, or stunted growth indicate temperature stress.
Cold Stress
Low temperatures slow metabolic processes, leading to root damage and reduced flowering.
Solution: Move to a warmer location, insulate pots, and reduce watering during cold spells.
Hot Stress
Excessive heat causes wilting, leaf scorch, and dehydration, especially if humidity is low.
Solution: Provide shade, increase humidity, and water more frequently during heatwaves.
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.
