Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; avoid direct sun, especially in summer. Adjust intensity with sheer curtains or filtered light.
Sunlight Tolerance Tips:
Acclimate gradually to new light conditions; protect from intense midday sun; place in east-facing windows or shaded outdoor spots.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even growth; use sheer blinds to diffuse strong light; avoid south-facing windows in summer.
Watering
every 7–10 days during active growth, reducing frequency in winter
Water early in the day to allow foliage to dry; avoid wetting the crown to prevent rot; ensure thorough watering reaches root zone.
Soil
well-draining orchid mix with bark and perlite
pH: Slightly acidic to neutral (pH 5.5–6.5).
Use orchid-specific mix; avoid heavy potting soils; ensure pots have drainage holes.
Temperature
Moderate temperatures: 60–75°F (15–24°C) during the day, 50–60°F (10–15°C) at night. Cooler nights promote blooming.
Avoid sudden temperature changes; ensure 10–15°F (5–8°C) diurnal fluctuation; protect from drafts.
Fertilizing
every 2 weeks during active growth with diluted orchid fertilizer, none in winter
Flush soil monthly with plain water to prevent salt buildup; fertilize after watering to avoid root burn.
Propagation
Methods
Division of pseudobulbs; mature plants can be split into clumps with 3–4 pseudobulbs each.
Step-by-Step Propagation Guide
- Separate pseudobulbs with roots.
- Pot in orchid mix.
- Water lightly.
- Maintain humidity.
- Provide indirect light.
Best Time: After flowering, in late spring or early summer when new growth begins.
Environment
High humidity (60–80%), warm temperatures (65–75°F), and bright indirect light.
Medium
Orchid mix (bark, sphagnum, perlite) with high humidity and indirect light.
Hormone
Not typically required for division; rooting hormone may aid stem cuttings if used.
Timeline
Division establishes in 1–2 months; flowering may take 6–12 months post-propagation.
Tools Needed
Clean knife, sterilized shears, orchid mix, humidity dome or plastic bag.
Quick Tips
Ensure each division has healthy roots; keep new plants shaded initially; avoid overwatering.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim yellow or dead leaves at the stem.
Pruning Plan
Remove spent flower spikes and dead foliage to redirect energy to new growth and blooms.
Tools
Sterilized pruning shears or scissors.
Checklist
Sterilize tools; cut dead parts; avoid live growth; clean debris from pot.
Repotting Guide
Best Season
Late spring or early summer after flowering, when new growth appears.
Pot Size
One size larger pot (e.g., +2–3 cm in diameter); ensure good drainage holes.
Method
Remove old medium; trim dead roots; repot in fresh orchid mix with good drainage; position pseudobulbs just above soil level.
Suggestions
Repot every 2–3 years or when potting medium decomposes; essential for healthy root growth.
Checklist
Prepare new pot; sterilize tools; trim roots; use fresh orchid mix; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; avoid crown wetting; adjust seasonally.
How to Apply Water Properly
Water until it drains freely from the bottom, ensuring even moisture without waterlogging. Focus on the root ball, avoiding direct contact with leaves or pseudobulbs. Allow excess water to drain completely before returning to the saucer.
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. Adjust based on humidity and temperature.
Soil Improvement
Add perlite or coarse bark to enhance aeration; incorporate sphagnum moss for moisture retention.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis, bud drop, stunted growth, or leaf spotting from extreme heat or cold.
Cold Stress
Slows metabolic processes, causing leaf discoloration, wilting, or root damage below 50°F (10°C).
Solution: Move to a warmer location; insulate pots; avoid drafts; maintain humidity to buffer temperature swings.
Hot Stress
Leaves may scorch, wilt, or drop; roots can desiccate in temperatures above 85°F (29°C).
Solution: Increase humidity; provide shade; water more frequently; use shade cloth outdoors.
Fertilizing Guide
Fertilizing Checklist
Use diluted orchid fertilizer; fertilize during growth periods; flush periodically; avoid winter feeding.
Fertilizing Method
Use balanced orchid fertilizer (20-20-20) at half strength every 2–4 weeks during active growth; reduce or stop in winter.
