Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to lower light in summer to prevent leaf burn; filtered sunlight is ideal.
Sunlight Tolerance Tips:
Gradually acclimate to brighter light to avoid scorching; provide shade during peak midday sun; adjust indoor placement to mimic natural dappled light.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Avoid direct sun; rotate plant for even light exposure; use sheer curtains for filtered light.
Watering
every 7–10 days during active growth, reducing to every 2–3 weeks in winter
Water early in the day to allow foliage to dry; ensure thorough watering reaches root zone; adjust frequency based on season and growth stage.
Soil
well-draining orchid mix with bark, charcoal, and perlite
pH: Slightly acidic (pH 5.5–6.5).
Use chunky orchid mix; ensure pots have drainage; avoid heavy potting soils.
Temperature
Ideal range 60–75°F (15–24°C); cooler nights (55–60°F) promote blooming; avoid extreme fluctuations.
Avoid sudden temperature changes; maintain cooler nights for blooming; protect from drafts.
Fertilizing
every 2 weeks during active growth with diluted orchid fertilizer, none in winter
Dilute fertilizer to prevent burn; fertilize after watering to avoid salt buildup; flush periodically with plain water.
Propagation
Methods
Division of pseudobulbs or backbulbs; occasionally through keikis (plantlets) on flower spikes.
Step-by-Step Propagation Guide
- Divide mature pseudobulbs with at least 3 growths.
- Sterilize cuts.
- Plant in fresh medium.
- Maintain high humidity.
Best Time: After flowering, during early spring when new growth begins.
Environment
High humidity (70–80%), warm temperatures (65–75°F), indirect light, and good air circulation.
Medium
Fine orchid bark mix or sphagnum moss with perlite for drainage.
Hormone
Optional, but recommended for backbulbs to encourage root development.
Timeline
Roots develop in 4–8 weeks; establishment may take 6–12 months.
Tools Needed
Sterile knife, pruning shears, rooting hormone (optional), humidity dome or plastic bag.
Quick Tips
Ensure divisions have healthy roots; maintain consistent moisture; provide warmth for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead leaves or pseudobulbs just above the next viable node.
Pruning Plan
Focus on removing spent flower spikes and dead or damaged growth to redirect energy to new growth and blooms.
Tools
Sterile pruning shears or scissors, disinfectant.
Checklist
Sterilize tools; prune after flowering; remove dead material; avoid cutting healthy growth.
Repotting Guide
Best Season
Early spring, just before new growth emerges.
Pot Size
Choose a pot one size larger (1–2 inches wider) than the current one; ensure ample drainage holes.
Method
Remove old medium; trim dead roots; repot in fresh orchid mix with good drainage; position pseudobulbs above soil level.
Suggestions
Repot every 2–3 years or when medium decomposes; essential for root health and blooming.
Checklist
Prepare new pot and medium; trim roots; position plant correctly; 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 freely from the bottom, ensuring even moisture distribution without waterlogging; focus on the root ball and avoid wetting the pseudobulbs directly to prevent rot.
Watering Schedule Tips
Water thoroughly when the top inch of soil feels dry, typically every 7–10 days during active growth (spring/summer); reduce frequency to every 2–3 weeks in winter dormancy.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate sphagnum moss for moisture retention; use orchid-specific fertilizer.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf spotting in excessive heat; bud drop or stunted growth in cold stress.
Cold Stress
Slows metabolic processes, causing root damage and reduced nutrient uptake; may lead to leaf discoloration or necrosis.
Solution: Move to a warmer location; insulate pots; avoid cold drafts; maintain consistent temperatures above 50°F (10°C).
Hot Stress
Causes wilting, leaf scorch, and dehydration; may trigger premature flowering or bud abortion.
Solution: Increase humidity; provide shade; water more frequently; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted orchid fertilizer; fertilize during growing season; flush soil occasionally.
Fertilizing Method
Use balanced orchid fertilizer (20-20-20) diluted to half strength every 2–4 weeks during active growth; cease in winter.
