Care Details
Ideal Sunlight Coverage:
Bright indirect light for 4–6 hours daily; direct morning sun is tolerated but avoid harsh afternoon sun, especially in summer.
Sunlight Tolerance Tips:
Acclimate plants gradually to brighter light; use sheer curtains to filter intense sun; move outdoor plants to shaded areas during peak heat.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light with some morning sun
Rotate plant weekly for even light; avoid direct midday sun; provide dappled shade in summer.
Watering
every 5–7 days during active growth, reducing to every 10–14 days in winter
Water early in the day to allow foliage to dry; avoid waterlogging the roots; ensure good drainage to prevent rot.
Soil
orchid bark mix with perlite and charcoal for excellent drainage
pH: Slightly acidic (pH 5.5–6.5).
Use orchid-specific mix; ensure medium is chunky for air circulation; replace every 2–3 years.
Temperature
Optimal range 60–80°F (15–27°C); prefers cooler nights (55–65°F) during winter to promote blooming.
Maintain stable temperatures; provide cooler nights in winter; avoid sudden temperature swings.
Fertilizing
every 2 weeks during active growth with a balanced orchid fertilizer, reducing to monthly in winter
Flush pots monthly with plain water to prevent salt buildup; fertilize after watering to avoid root burn.
Propagation
Methods
Stem cuttings (keikis) or division of mature pseudobulb clumps.
Step-by-Step Propagation Guide
- Select a healthy pseudobulb.
- Cut below a node for keikis.
- Divide clumps into 3–4 pseudobulb sections.
- Plant in fresh medium.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (70–80°F), and bright indirect light.
Medium
Fine orchid bark mix or sphagnum moss with perlite for drainage.
Hormone
Optional, but rooting hormone can speed up keiki development.
Timeline
Keikis may take 3–6 months to form roots; division plants establish in 1–2 growing seasons.
Tools Needed
Sterile knife, pruning shears, rooting hormone (optional), pots, orchid mix.
Quick Tips
Keep cuttings humid; ensure divisions have healthy roots; avoid overwatering new plants.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead pseudobulbs just above the base; avoid cutting into healthy tissue.
Pruning Plan
Focus on removing spent flower spikes and dead or damaged pseudobulbs to redirect energy to new growth.
Tools
Sterile pruning shears, sharp knife.
Checklist
Sterilize tools; cut dead material; avoid over-pruning; clean debris from pot.
Repotting Guide
Best Season
Late winter or early spring before new growth begins.
Pot Size
Choose a pot one size larger (1–2 inches wider) than the current one; ensure good drainage.
Method
Remove old medium; trim dead roots; place in a pot with fresh orchid mix, ensuring pseudobulbs sit above the medium level.
Suggestions
Repot every 2–3 years or when medium breaks down; essential for healthy root growth and blooming.
Checklist
Clean roots; use fresh medium; ensure proper drainage; position pseudobulbs correctly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water early morning; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water directly at the root zone, allowing water to saturate the medium but not pool; ensure excess water drains freely; avoid wetting the pseudobulbs and leaves to reduce fungal risk.
Watering Schedule Tips
Water thoroughly when the top inch of soil is dry, typically every 7–10 days during active growth (spring/summer); reduce frequency to every 2–3 weeks in winter or dormant periods.
Soil Improvement
Add perlite or coarse sand to increase drainage; incorporate sphagnum moss for water retention.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf burn in excessive heat; stunted growth or bud drop 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; maintain humidity to buffer temperature fluctuations.
Hot Stress
Leaves may wilt, scorch, or drop; flowers may fade prematurely in temperatures above 90°F (32°C).
Solution: Provide shade; increase air circulation; mist foliage (avoiding flowers) during heatwaves; ensure consistent watering.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during growing season; flush periodically.
Fertilizing Method
Use a balanced orchid fertilizer (20-20-20) at half-strength every 2–4 weeks during active growth; reduce or stop in winter.
