- Pruning Frequency: As needed after flowering or when dead material is present; typically annually.
- Pruning Intensity: Light to moderate; remove only non-viable parts without overcutting healthy growth.
Care Details
Ideal Sunlight Coverage:
Bright indirect light for 4–6 hours daily; direct morning sun is tolerated but avoid harsh afternoon sun, especially in summer.
Sunlight Tolerance Tips:
Acclimate plants gradually to higher light levels; use sheer curtains to filter intense sunlight; place outdoors in dappled shade during warmer months.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light with some morning sun
Rotate plant weekly for even light exposure; avoid direct midday sun; provide shade during peak summer hours.
Watering
every 5–7 days during active growth, reducing to every 10–14 days in winter
Water thoroughly until water drains from the bottom; allow the potting medium to dry slightly between waterings; avoid wetting the pseudobulbs directly.
Soil
orchid bark mix with perlite and charcoal for excellent drainage
pH: Slightly acidic (pH 5.5–6.5).
Use a well-aerated mix; avoid heavy potting soils; replace medium every 2–3 years.
Temperature
Ideal range 60–80°F (15–27°C); prefers cooler nights (55–65°F) during winter dormancy to encourage blooming.
Maintain consistent day/night temperature differences; avoid placing near heating/cooling vents; monitor temperature during seasonal shifts.
Fertilizing
every 2 weeks during active growth with a balanced orchid fertilizer, every 4 weeks in winter
Flush pots with plain water monthly to prevent salt buildup; fertilize after watering to avoid root burn; adjust frequency based on growth phase.
Propagation
Methods
Stem cuttings (keikis) or division of mature pseudobulbs.
Step-by-Step Propagation Guide
- Select a healthy pseudobulb.
- Cut below a node or aerial root.
- Apply rooting hormone if desired.
- Place in moist 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 bright indirect light.
Medium
Fine orchid bark mix or sphagnum moss with perlite for drainage.
Hormone
Rooting hormone is optional but can speed up root development.
Timeline
Keikis may form in 4–8 weeks; division may take 6–12 months to establish.
Tools Needed
Clean knife or shears, rooting hormone, propagation tray, humidity dome.
Quick Tips
Keep cuttings moist but not waterlogged; provide bottom heat for faster rooting; monitor for signs of rot.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead pseudobulbs just above the base; avoid cutting into healthy growth.
Pruning Plan
Focus on removing spent flower spikes and dead or damaged pseudobulbs to redirect energy to new growth.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; cut at the base; remove only dead/damaged parts; clean debris from the pot.
Repotting Guide
Best Season
Late spring or early summer after flowering and before new growth begins.
Pot Size
One size larger pot (e.g., 2–3 cm increase in diameter); ensure it has drainage holes.
Method
Remove old medium gently; trim 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 medium breaks down; essential for healthy root growth and blooming.
Checklist
Prepare new pot with drainage; remove old medium; inspect roots; trim if necessary; use fresh orchid mix; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water early in the day; ensure proper drainage; adjust frequency with seasons.
How to Apply Water Properly
Water at the base of the plant, ensuring even moisture reaches the root zone. Water until it drains freely from the pot’s bottom, avoiding prolonged standing water.
Watering Schedule Tips
Water every 5–7 days during active growth (spring/summer), reducing to every 10–14 days in winter. Adjust based on humidity and temperature.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate sphagnum moss for moisture retention; use orchid-specific fertilizers to maintain fertility.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf burn in excessive heat; stunted growth or bud drop in cold stress.
Cold Stress
Low temperatures slow metabolic processes, leading to root damage and reduced flowering.
Solution: Protect from drafts and temperatures below 50°F; provide a heat source if necessary; ensure good air circulation to prevent fungal issues.
Hot Stress
Excessive heat causes dehydration, leaf scorch, and bud blast if humidity and ventilation are insufficient.
Solution: Increase humidity with misting or a humidifier; provide shade; ensure adequate air circulation to prevent heat buildup.
Fertilizing Guide
Fertilizing Checklist
Use diluted orchid fertilizer; fertilize during active growth; flush periodically; avoid winter fertilization.
Fertilizing Method
Use a balanced orchid fertilizer (20-20-20) diluted to half strength every 2–4 weeks during active growth; reduce or stop in winter.
