Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to morning sun in winter and dappled shade in summer.
Sunlight Tolerance Tips:
Gradually acclimate to brighter light to prevent leaf burn; provide shade during intense midday sun; rotate regularly for even growth.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Avoid direct afternoon sun; use sheer curtains for filtered light; place near east-facing windows.
Watering
every 7–10 days during active growth, reducing to every 2–3 weeks in winter
Water early in the day to allow foliage to dry; ensure water reaches the root zone; avoid overwatering.
Soil
well-draining orchid mix with perlite and bark
pH: Slightly acidic (pH 5.5–6.5).
Ensure water drains quickly; avoid heavy potting soils; maintain slightly moist but not wet conditions.
Temperature
Ideal range 60–80°F (15–27°C); cooler temperatures (55–65°F) at night promote blooming.
Avoid sudden temperature changes; maintain consistent night/day cycles; protect from drafts.
Fertilizing
every 2 weeks during active growth with balanced liquid fertilizer, none in winter
Flush soil periodically to prevent salt buildup; fertilize after watering to avoid root burn; adjust for blooming phase.
Propagation
Methods
Stem cuttings or division of pseudobulbs.
Step-by-Step Propagation Guide
- Select healthy pseudobulb, sterilize cutting, apply rooting hormone, plant in medium, maintain humidity, provide indirect light.
Best Time: Spring or early summer when the plant is actively growing.
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 speed up rooting.
Timeline
Roots develop in 4–8 weeks; new growth may take 3–6 months.
Tools Needed
Sterilized knife, rooting hormone, propagation tray, humidity dome.
Quick Tips
Keep cuttings moist but not waterlogged; maintain consistent warmth; avoid direct sunlight.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead leaves just above the node.
Pruning Plan
Remove spent flower spikes and dead foliage to encourage new growth and maintain plant health.
Tools
Sterilized pruning shears, sharp scissors.
Checklist
Sterilize tools, cut at the base, remove dead parts, clean up debris.
Repotting Guide
Best Season
Spring or early summer before new growth begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure it is not too large.
Method
Remove old medium, trim dead roots, repot in fresh orchid mix, ensure good drainage, water lightly after repotting.
Suggestions
Repot every 2–3 years or when the potting medium breaks down; necessary for root-bound plants.
Checklist
Prepare new pot, trim roots, add fresh medium, water sparingly, place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, adjust for season.
How to Apply Water Properly
Water until it drains from the bottom, ensuring even moisture distribution; focus on the root ball; 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 for drainage; incorporate orchid bark for aeration; use charcoal to absorb toxins.
Temperature Stress Management
Signs of Temperature Issues
Leaf yellowing or browning, bud drop, stunted growth, or wilting.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage if temperatures drop below 50°F (10°C).
Solution: Move to a warmer location, insulate pots, and avoid cold drafts; use grow lights for added warmth.
Hot Stress
Leaves may wilt, scorch, or drop; growth may cease in excessive heat above 90°F (32°C).
Solution: Provide shade, increase humidity, and water more frequently; use cooling fans if indoors.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply 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 in winter.
