Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust for seasonal light intensity.
Sunlight Tolerance Tips:
Acclimate plants gradually to direct sunlight; avoid sudden exposure to intense sun; provide shade during peak hours for outdoor plants.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to filtered light
Rotate plant for even light exposure; use sheer curtains to filter intense sunlight; monitor for signs of sunburn.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure good drainage; avoid waterlogged soil.
Soil
well-draining, humus-rich potting mix
pH: Slightly acidic to neutral (pH 5.5–6.5).
Use orchid-specific mix; avoid heavy garden soils; ensure pots have drainage holes.
Temperature
Prefers 60–80°F (15–27°C); cooler temperatures (50–60°F or 10–15°C) during dormancy.
Avoid sudden temperature changes; protect from drafts; maintain consistent temperatures during active growth.
Fertilizing
every 4–6 weeks during growing season
Fertilize after watering to prevent root burn; flush soil periodically to prevent salt buildup; adjust frequency based on growth rate.
Propagation
Methods
Division of pseudobulbs; occasionally by seed (challenging for home growers).
Step-by-Step Propagation Guide
- Divide pseudobulbs with at least 2–3 growths.
- Plant in fresh orchid mix.
- Water lightly until established.
Best Time: After flowering, when new growth begins in spring or early summer.
Environment
Warm, humid, and shaded environment with indirect light.
Medium
Orchid mix with perlite or coarse sand for good drainage.
Hormone
Not typically required for division; rooting hormone may aid seed propagation.
Timeline
Division: immediate establishment; seed: 1–2 years to flowering.
Tools Needed
Clean knife, sterilized pots, orchid mix, rooting hormone (optional).
Quick Tips
Ensure each division has healthy roots; keep humidity high during initial rooting; avoid overwatering.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim foliage just above the node or base.
Pruning Plan
Remove spent flower spikes and dead or damaged foliage to encourage new growth and maintain plant health.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sterilize tools; remove dead parts; cut cleanly; dispose of debris.
Repotting Guide
Best Season
Spring, after flowering, when new growth starts.
Pot Size
One size larger pot; ensure it has drainage holes.
Method
Remove old medium; trim roots if necessary; repot in fresh orchid mix with good drainage; position pseudobulbs just above soil level.
Suggestions
Repot every 2–3 years or when the orchid outgrows its pot; necessary when medium decomposes.
Checklist
Prepare new pot; remove old medium; inspect roots; plant at proper depth; water lightly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
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 to improve drainage; incorporate organic matter for fertility; ensure medium is well-aerated.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, wilting, or bud drop in extreme heat or cold.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage in freezing temperatures.
Solution: Move to a warmer location; insulate pots; avoid cold drafts; protect from frost.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow in excessive heat.
Solution: Provide shade; increase humidity; water more frequently; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during growing season; flush soil occasionally.
Fertilizing Method
Use a balanced orchid fertilizer diluted to half strength every 4–6 weeks during active growth; reduce or stop in winter.
