Care Requirements
Care Difficulty
challengingmoderate
Sunlight
filtered light or partial shade
Use sheer curtains to filter light; rotate plant weekly for even growth; avoid south-facing windows in summer.
Watering
every 5–7 days during active growth, reducing to every 10–14 days in cooler months
Water early in the day to allow foliage to dry; avoid wetting the crown to prevent fungal issues.
Soil
well-draining orchid mix with bark and sphagnum moss
pH: Slightly acidic, pH 5.5–6.5.
Use a well-aerated mix; avoid heavy potting soils; ensure pots have drainage holes.
Temperature
Cool to moderate temperatures, ideally 50–65°F (10–18°C); prefers cooler nights.
Avoid placing near drafty windows; maintain stable temperatures; monitor for signs of stress.
Fertilizing
every 2 weeks during active growth with diluted orchid fertilizer, none in winter
Fertilize after watering to prevent root burn; flush soil periodically to prevent salt buildup; avoid over-fertilizing.
Propagation
Methods
Division of pseudobulbs or offsets; stem cuttings can also be used.
Step-by-Step Propagation Guide
- Separate offsets with at least one pseudobulb.
- Pot in fresh medium.
- Maintain high humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (65–75°F), and indirect light.
Medium
Fine orchid bark mix or sphagnum moss with perlite for drainage.
Hormone
Rooting hormone is optional but can aid in faster root development.
Timeline
Roots may develop in 4–8 weeks; new growth in 3–6 months.
Tools Needed
Clean knife, sterile pot, rooting hormone (optional), humidity dome.
Quick Tips
Ensure each division has healthy roots; maintain consistent moisture; provide gentle air circulation.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim foliage just above a node or healthy growth point.
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; cut dead or damaged parts; avoid over-pruning healthy growth.
Repotting Guide
Best Season
Spring, just before the active growing season begins.
Pot Size
Choose a pot one size larger than the current one; ensure it has drainage holes.
Method
Remove old medium; trim dead roots; repot in fresh orchid mix with good drainage.
Suggestions
Repot every 1–2 years or when the medium breaks down; necessary for root-bound plants.
Checklist
Prepare new pot and medium; handle roots gently; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure proper drainage; avoid crown wetting.
How to Apply Water Properly
Water until it drains from the bottom, ensuring even moisture without waterlogging; focus on the root zone and avoid leaves.
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 for drainage; incorporate orchid bark for aeration.
Temperature Stress Management
Signs of Temperature Issues
Leaf discoloration, bud drop, or stunted growth; wilting in excessive heat.
Cold Stress
Slows growth and can cause root damage; may lead to fungal infections in overly moist conditions.
Solution: Provide insulation with mulch; avoid cold drafts; maintain consistent temperatures above 50°F (10°C).
Hot Stress
Causes wilting, leaf scorch, and reduced flowering; increases water demand.
Solution: Increase humidity with misting or pebble trays; provide shade; water more frequently.
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.
