- Pruning Intensity: Light to moderate; remove only dead or non-functional parts.
Care Details
Ideal Sunlight Coverage:
Bright indirect light for 4–6 hours daily; can tolerate morning sun but avoid harsh afternoon sun, especially during summer.
Sunlight Tolerance Tips:
Acclimate gradually to brighter light to prevent leaf burn; provide shade during peak sun hours; adjust light exposure based on indoor vs. outdoor placement.
Care Requirements
Care Difficulty
challengingmoderate
Sunlight
bright, indirect light
Avoid direct midday sun; rotate plant for even light exposure; use sheer curtains to filter intense light.
Watering
every 7–10 days during active growth, reduce to every 3–4 weeks during dormancy
Water thoroughly until water drains from the bottom; ensure soil dries slightly between waterings; adjust frequency based on season and growth stage.
Soil
well-draining orchid mix with bark and perlite
pH: Slightly acidic to neutral (pH 5.5–6.5).
Ensure mix is well-aerated; avoid heavy potting soils; maintain consistent moisture without saturation.
Temperature
Prefers warm temperatures (65–85°F or 18–29°C) during active growth; cooler temperatures (50–60°F or 10–15°C) during dormancy to induce blooming.
Monitor temperature fluctuations; provide shade in summer; adjust watering in response to temperature changes.
Fertilizing
every 2 weeks during active growth with balanced liquid fertilizer, none during dormancy
Dilute fertilizer to avoid burning roots; fertilize after watering to prevent salt buildup; stop fertilizing during dormancy.
Propagation
Methods
Division of pseudobulbs during repotting; mature plants can be split into smaller clumps with at least 3 pseudobulbs each.
Step-by-Step Propagation Guide
- Carefully divide the plant into clumps with 3+ pseudobulbs.
- Pot each division in fresh orchid mix.
- Water sparingly until new roots form.
Best Time: Spring, when the plant is actively growing and before new growth emerges.
Environment
Warm, humid environment with bright indirect light; maintain consistent moisture but ensure good air circulation.
Medium
Orchid mix with good drainage (e.g., bark, perlite, charcoal); can also be mounted on cork or tree fern.
Hormone
Not typically required for division; rooting hormone may help if using stem cuttings (less common).
Timeline
New growth may appear within 4–6 weeks; full establishment can take several months.
Tools Needed
Clean knife or shears, sterile potting mix, pots with drainage.
Quick Tips
Ensure each division has healthy pseudobulbs; keep humidity high after division; avoid overwatering new divisions.
Pruning & Repotting
Pruning Guide
Method
Cut spent flower spikes at the base; remove dead pseudobulbs carefully to avoid damaging healthy ones.
Pruning Plan
Minimal pruning needed; focus on removing dead or damaged pseudobulbs and spent flower spikes to encourage new growth.
Tools
Clean, sharp scissors or pruners.
Checklist
Sterilize tools before use; cut dead or damaged parts; avoid over-pruning healthy growth.
Repotting Guide
Best Season
Spring, just before the start of the active growing season.
Pot Size
One size larger pot (e.g., 1–2 inches wider in diameter); ensure pot has drainage holes.
Method
Remove plant from pot; trim any dead roots; place in a slightly larger pot with fresh orchid mix; ensure good drainage.
Suggestions
Repot every 2–3 years or when the potting mix breaks down; necessary to refresh media and provide space for new growth.
Checklist
Use fresh orchid mix; ensure good drainage; position pseudobulbs just above soil level; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water thoroughly; ensure proper drainage; adjust for season.
How to Apply Water Properly
Water directly onto the root zone, ensuring even moisture distribution; water early in the day to allow foliage to dry; ensure excess water drains freely to prevent root rot.
Watering Schedule Tips
Water generously during active growth (spring-summer), allowing soil to dry slightly between waterings; reduce watering significantly in fall as the plant enters dormancy; keep almost dry during winter dormancy.
Soil Improvement
Add perlite or coarse bark to improve drainage; incorporate charcoal to absorb impurities; use orchid-specific fertilizer to enhance fertility.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, bud drop, or stunted growth in excessive heat; leaf damage or failure to resume growth in cold stress.
Cold Stress
Low temperatures can cause leaf damage, slow growth, and inhibit flowering; prolonged cold may lead to root rot.
Solution: Move plant to a warmer location; provide insulation if outdoors; avoid cold drafts and sudden temperature drops.
Hot Stress
Excessive heat can lead to wilting, leaf scorch, and reduced vigor; may cause premature dormancy if not managed.
Solution: Provide shade during peak heat; increase humidity; ensure adequate air circulation; water more frequently if heat is prolonged.
Fertilizing Guide
Fertilizing Checklist
Use diluted orchid fertilizer; fertilize during active growth only; rinse pot periodically to prevent salt accumulation.
Fertilizing Method
Use a balanced orchid fertilizer (20-20-20) diluted to half strength; fertilize every 2–4 weeks during active growth (spring-summer); cease fertilizing during fall and winter dormancy.
