Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust for seasonal light intensity changes.
Sunlight Tolerance Tips:
Acclimate gradually to direct light; avoid intense midday sun; provide filtered light indoors or dappled shade outdoors.
Care Requirements
Care Difficulty
challengingmoderate
Sunlight
bright, indirect light
Rotate plant for even light exposure; use sheer curtains to filter intense light; avoid sudden light changes.
Watering
every 7–10 days during active growth, reducing frequency in winter
Water deeply but infrequently; ensure proper drainage; adjust based on season and growth phase.
Soil
well-draining orchid mix with bark and perlite
pH: Slightly acidic to neutral (pH 5.5–6.5).
Use orchid-specific mix; avoid heavy potting soils; ensure pots have drainage holes.
Temperature
Prefers 60–80°F (15–27°C); cooler temperatures (50–60°F or 10–15°C) tolerated in winter.
Avoid sudden temperature swings; protect from drafts; maintain stable conditions during flowering.
Fertilizing
every 2 weeks during active growth with diluted orchid fertilizer, none in winter
Dilute fertilizer to prevent burn; fertilize after watering; avoid foliage contact.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Select healthy stem, cut below node, apply hormone, place in medium, maintain humidity, wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (70–80°F or 21–27°C), indirect light.
Medium
Well-draining mix of perlite and peat moss or orchid bark.
Hormone
Rooting hormone recommended for faster root development.
Timeline
Roots may develop in 4–8 weeks; establishment takes 3–6 months.
Tools Needed
Pruning shears, rooting hormone, propagation tray, humidity dome, well-draining medium.
Quick Tips
Use sterile tools to prevent disease; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a node or leaf junction; remove spent flowers to redirect energy.
Pruning Plan
Remove dead or yellowing stems to encourage new growth and maintain shape.
Tools
Clean, sharp pruning shears or scissors, disinfectant.
Checklist
Sterilize tools, prune dead/damaged parts, make clean cuts, clean up debris, monitor recovery.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure good drainage.
Method
Remove plant gently, trim roots if needed, place in slightly larger pot with fresh orchid mix, water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; necessary to refresh soil and provide space.
Checklist
Choose appropriate pot, prepare fresh soil, handle roots carefully, water sparingly post-repotting, monitor for stress.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, adjust seasonally
How to Apply Water Properly
Water at the base of the plant, avoiding foliage; ensure water reaches the root zone; allow excess to drain completely; water in the morning to reduce evaporation.
Watering Schedule Tips
Water thoroughly when the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate organic matter for fertility; ensure chunky texture for air circulation.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, stunted growth, or browning leaf tips.
Cold Stress
Slows growth, may cause root damage or leaf discoloration below 50°F (10°C).
Solution: Move to a warmer location; insulate roots; avoid cold drafts; reduce watering.
Hot Stress
Leaf scorch, dehydration, or bud drop above 90°F (32°C).
Solution: Provide shade; increase humidity; water more frequently; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer, apply during growing season, avoid winter feeding, rinse tools after use
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
