Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily. Can tolerate direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate plants gradually to direct light; protect from intense midday sun; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light; tolerates some direct morning sun
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid shaded corners.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Allow soil to dry slightly between waterings; water thoroughly until it drains; avoid waterlogging.
Soil
well-draining orchid mix or epiphytic substrate
pH: Slightly acidic to neutral (pH 5.5–6.5).
Ensure pots have drainage holes; avoid compacted soil; use orchid-specific mixes.
Temperature
Ideal range 60–85°F (15–29°C). Prefers warm, stable conditions; tolerates mild fluctuations.
Avoid sudden temperature changes; protect from cold drafts; maintain consistent warmth during flowering.
Fertilizing
every 2 weeks during active growth (spring and summer), every 3 months with slow-release fertilizer in fall and winter
Clean foliage before fertilizing; avoid over-fertilizing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division of pseudobulbs.
Step-by-Step Propagation Guide
- Select healthy stem.
- Cut below node.
- Apply hormone (optional).
- Plant in medium.
- Maintain humidity.
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
Well-draining mix like orchid bark or perlite with peat moss.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 4–8 weeks; new growth may take 3–6 months.
Tools Needed
Pruning shears, rooting hormone, plastic bag or propagator, well-draining medium.
Quick Tips
Use sterile tools; keep medium moist but not waterlogged; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead leaves cleanly without damaging healthy tissue.
Pruning Plan
Remove spent flower spikes and dead foliage to encourage new growth and maintain plant health.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; cut dead material; avoid over-pruning; clean up debris.
Repotting Guide
Best Season
Spring, just before the active growing season begins.
Pot Size
One size larger pot (e.g., +2–3 cm in diameter).
Method
Remove plant gently; trim dead roots; place in slightly larger pot with fresh orchid mix; ensure good drainage.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound. Necessary to refresh soil and provide space.
Checklist
Choose appropriate pot; prepare fresh soil mix; handle roots carefully; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; discard excess water.
How to Apply Water Properly
Water directly at the root zone, ensuring even moisture distribution. Water until excess drains from the bottom, then discard any standing water. Water in the morning to allow foliage to dry.
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 for drainage; incorporate organic matter like orchid bark for aeration.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis (yellowing leaves), bud drop, stunted growth, or leaf burn.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root rot if soil remains wet.
Solution: Move to a warmer location; protect from drafts; ensure soil dries faster in cooler conditions.
Hot Stress
Wilting, leaf scorch, or reduced flowering due to excessive heat and dryness.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer (20-20-20) diluted to half strength every 4–6 weeks during growing season (spring/summer). Reduce or stop in fall/winter.
