Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to morning sun with filtered afternoon shade in warmer months.
Sunlight Tolerance Tips:
Acclimate gradually to direct sun; protect from intense midday sun; provide dappled light for outdoor placement.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Avoid direct afternoon sun; rotate pot for even light exposure; use sheer curtains for indoor protection.
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; avoid wetting the crown to prevent fungal issues; ensure excellent drainage after each watering.
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 medium breaks down slowly.
Temperature
Prefers 60–80°F (15–27°C); cooler nights (55–65°F) may induce blooming; avoid extreme fluctuations.
Protect from frost; maintain stable temperatures; avoid placing near heating/cooling vents.
Fertilizing
every 2 weeks during active growth with a balanced orchid fertilizer, ceasing in winter
Flush potting medium monthly to prevent salt buildup; fertilize after watering to avoid root burn; adjust frequency based on growth phase.
Propagation
Methods
Stem cuttings (keikis) or division of pseudobulbs.
Step-by-Step Propagation Guide
- Select healthy pseudobulbs.
- Cut below a node.
- Apply rooting hormone.
- Place in moist medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (70–85°F), 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 can take 3–6 months.
Tools Needed
Clean knife or shears, rooting hormone, propagation tray, humidity dome.
Quick Tips
Keep cuttings warm and humid; avoid direct sun; check for root development every few weeks.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead pseudobulbs with clean, sharp tools.
Pruning Plan
Focus on removing spent flower spikes and dead or damaged pseudobulbs to encourage new growth and blooming.
Tools
Clean pruning shears or scissors, sterilizing solution.
Checklist
Sterilize tools; remove dead material; cut flower spikes cleanly; avoid over-pruning.
Repotting Guide
Best Season
Spring, just before the start of the growing season.
Pot Size
One size larger pot (e.g., +2–3 cm in diameter); ensure it has drainage holes.
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 potting medium decomposes; essential for healthy root growth.
Checklist
Prepare new pot with drainage; remove old medium gently; trim roots; position plant; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water early morning; ensure drainage; reduce in winter; avoid crown wetting.
How to Apply Water Properly
Water directly onto the potting medium, avoiding the crown; ensure water reaches the root zone; allow excess to drain completely; water less frequently during dormancy.
Watering Schedule Tips
Water thoroughly when the top 1–2 inches of potting medium are dry; reduce frequency in winter or cooler periods to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate orchid bark for aeration; use sphagnum moss for moisture retention.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis, bud drop, or stunted growth in excessive heat; leaf spotting or root rot in cold stress.
Cold Stress
Slows metabolic processes; can cause root damage or leaf discoloration below 50°F (10°C).
Solution: Move to a warmer location; insulate pots; avoid cold drafts; reduce watering in cool conditions.
Hot Stress
Leaves may wilt, scorch, or drop; reduced blooming in prolonged heat above 90°F (32°C).
Solution: Provide shade; increase humidity; water more frequently; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted orchid fertilizer; fertilize during growing season; flush periodically; avoid winter feeding.
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.
