Sunlight Tolerance Tips:
Acclimate gradually to direct light; avoid intense afternoon sun to prevent leaf burn; place in east-facing windows indoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even light; use sheer curtains to filter intense light.
Watering
every 7–10 days during active growth, reduce in winter
Water early in the day to allow foliage to dry; ensure proper drainage to avoid waterlogging.
Soil
well-draining orchid mix
pH: Slightly acidic (pH 5.5–6.5).
Use pre-made orchid mix; avoid regular potting soil which retains too much moisture.
Temperature
Ideal range 60–80°F (15–27°C); prefers cooler nights in winter.
Avoid sudden temperature changes; maintain consistent room temperature.
Fertilizing
every 2 weeks during active growth, every 4–6 weeks in winter
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Division of pseudobulbs; occasionally through backbulbs or keikis.
Step-by-Step Propagation Guide
- Divide mature pseudobulbs, ensure each has roots.
- Pot in fresh medium, water lightly, maintain humidity.
Best Time: Spring or early summer when new growth begins.
Environment
High humidity (70–80%), warm temperatures (70–80°F), and indirect light.
Medium
Fine orchid bark mix or sphagnum moss with perlite.
Hormone
Rooting hormone is optional but can aid in faster rooting.
Timeline
Roots develop in 4–8 weeks; establishment takes 3–6 months.
Tools Needed
Clean knife, sterilized pot, rooting hormone (optional), humidity dome.
Quick Tips
Use sterile tools to prevent infection; maintain consistent moisture without waterlogging.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead pseudobulbs with clean cuts.
Pruning Plan
Remove spent flower spikes and dead pseudobulbs to redirect energy to new growth.
Tools
Sterilized pruning shears, sharp knife.
Checklist
Identify dead parts, use clean tools, make precise cuts, dispose of debris.
Repotting Guide
Best Season
Spring, after flowering when new growth starts.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure it’s not too large.
Method
Remove old medium, trim dead roots, repot in fresh orchid mix with good drainage.
Suggestions
Repot every 2–3 years or when medium decomposes; necessary for root bound plants.
Checklist
Prepare new pot, remove old medium, inspect roots, trim if needed, repot, water lightly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, adjust for season.
How to Apply Water Properly
Water the root zone directly, ensuring even moisture without saturating the pot; allow excess water to drain completely.
Watering Schedule Tips
Water thoroughly when the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate orchid bark for aeration.
Temperature Stress Management
Signs of Temperature Issues
Leaf yellowing, bud drop, or stunted growth indicate temperature stress.
Cold Stress
Prolonged cold slows growth and may cause root damage.
Solution: Move to a warmer location; insulate pots in cold drafts.
Hot Stress
Excessive heat can lead to dehydration and leaf scorch.
Solution: Provide shade during peak heat; increase humidity with misting or pebble trays.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply during active growth, reduce in dormancy.
Fertilizing Method
Use balanced orchid fertilizer diluted to half strength; fertilize monthly during growing season, reduce in winter.
