Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6-8 hours daily; can tolerate direct morning sun but avoid harsh afternoon sun, especially in summer.
Sunlight Tolerance Tips:
Acclimate gradually to direct light; use sheer curtains to filter intense sun; place in east-facing windows for optimal light without scorching.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even light exposure; avoid sudden light changes; provide dappled shade during peak summer.
Watering
every 7–10 days during active growth, reduce in winter
Water early in the day to allow foliage to dry; ensure water reaches root zone without pooling; adjust frequency based on season and humidity.
Soil
well-draining orchid mix with bark and perlite
pH: Slightly acidic to neutral (pH 5.5-6.5).
Use pre-made orchid mix; avoid heavy potting soils; ensure medium breaks down slowly.
Temperature
Prefers 65-85°F (18-29°C); tolerates brief dips to 50°F (10°C) but thrives in warm, stable conditions with slight drop at night.
Maintain stable temperatures; avoid drafts; use a thermometer to monitor microclimates.
Fertilizing
every 2 weeks during active growth with diluted orchid fertilizer, none in winter
Dilute fertilizer to avoid burning roots; fertilize after watering to prevent nutrient shock; adjust frequency based on growth phase.
Propagation
Methods
Stem cuttings (keikis) or division of mature pseudobulbs.
Step-by-Step Propagation Guide
- Select healthy pseudobulb or keiki.
- Sterilize cutting tool.
- Apply rooting hormone if using.
- Plant in medium.
- Maintain humidity and warmth.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70-80%), warm temperatures (75-85°F), indirect light, and good air circulation.
Medium
Fine orchid bark mix or sphagnum moss with perlite for aeration.
Hormone
Rooting hormone is optional but can speed up root development.
Timeline
Roots develop in 4-8 weeks; establishment may take 3-6 months.
Tools Needed
Sterilized pruning shears, rooting hormone (optional), humidity dome or plastic bag, orchid mix.
Quick Tips
Keep medium consistently moist but not waterlogged; provide bottom heat for faster rooting; avoid direct sunlight during rooting phase.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead pseudobulbs at the base; use clean, sharp tools to avoid infection.
Pruning Plan
Remove spent flower spikes and dead pseudobulbs to redirect energy to new growth; shape plant for better air circulation.
Tools
Sterilized pruning shears, sharp knife, disinfectant.
Checklist
Sterilize tools; cut at base; remove only dead/damaged parts; clean debris from pot.
Repotting Guide
Best Season
Spring, just before new growth begins.
Pot Size
One size larger pot (1-2 inches wider in diameter); ensure adequate drainage holes.
Method
Remove old medium; trim dead roots; place in slightly larger pot with fresh orchid mix; ensure good drainage.
Suggestions
Repot every 2-3 years or when medium decomposes; essential for healthy root growth and nutrient uptake.
Checklist
Prepare new pot with drainage; sterilize tools; trim roots if needed; use fresh orchid mix; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water early morning; ensure proper drainage; adjust for season.
How to Apply Water Properly
Water until it drains from the bottom, ensuring even moisture distribution; focus on the root ball, avoiding direct contact with pseudobulbs to prevent rot; allow excess water to drain completely.
Watering Schedule Tips
Water thoroughly during active growth (spring-summer) every 7-10 days, allowing soil to dry slightly between waterings; reduce frequency to every 2-3 weeks in fall-winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate orchid bark for aeration; use sphagnum moss for water retention.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or necrosis on leaves; bud drop; stunted growth; wilting despite adequate water.
Cold Stress
Slows metabolic processes; causes root damage; may lead to fungal infections in damp conditions.
Solution: Move to a warmer location; insulate pot with bubble wrap; avoid overwatering during cold spells.
Hot Stress
Leaves may scorch or curl; dehydration accelerates; reduced flowering due to excessive transpiration.
Solution: Increase humidity with misting or pebble trays; provide shade during peak heat; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Use orchid-specific fertilizer; dilute to half strength; fertilize during growing season only; flush periodically.
Fertilizing Method
Use balanced orchid fertilizer (20-20-20) at half strength every 2-4 weeks during active growth; cease in winter; flush roots monthly to prevent salt buildup.
