Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to morning sun in winter.
Sunlight Tolerance Tips:
Acclimate gradually to direct light, avoid harsh afternoon sun, and place in filtered light indoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light; protected from direct sunlight
Rotate plant weekly; use sheer curtains for protection; avoid south-facing windows in summer.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly until it drains, avoid wetting leaves, and ensure soil dries between waterings.
Soil
well-draining, peat-based potting mix with added perlite or sand
pH: Slightly acidic to neutral (6.0–7.0).
Avoid heavy clay; use orchid bark for texture; test pH annually.
Temperature
Ideal range 65–75°F (18–24°C); cooler in winter but avoid frost.
Avoid sudden temperature swings; use a thermometer; group plants for humidity.
Fertilizing
every 2–4 weeks during active growth (spring and summer), with a balanced liquid fertilizer diluted to half strength
Fertilize after watering; flush soil occasionally; avoid over-fertilizing.
Propagation
Methods
Stem cuttings with leaf nodes.
Step-by-Step Propagation Guide
- Take cutting, apply hormone, plant in medium, cover with plastic, keep moist.
Best Time: Spring or early summer when growth is active.
Environment
High humidity (70–80%), warm (70°F/21°C), indirect light.
Medium
Peat-based mix with perlite or sand for drainage.
Hormone
Recommended to promote root growth.
Timeline
Roots in 3–4 weeks; establish in 2–3 months.
Tools Needed
Pruners, rooting hormone, small pots, plastic wrap.
Quick Tips
Use healthy stems; keep consistently moist; remove lower leaves.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips, cut just above a leaf node, remove dead/damaged stems.
Pruning Plan
Remove leggy growth, encourage bushier form, and maintain shape.
Tools
Clean pruners, sterilized scissors.
Checklist
Sanitize tools, cut at an angle, remove debris, disinfect after use.
Repotting Guide
Best Season
Spring before active growth begins.
Pot Size
One size larger pot; ensure 1–2 inches of extra space.
Method
Remove gently, trim roots if needed, use fresh soil, ensure drainage.
Suggestions
Repot every 1–2 years or when roots fill the pot; promotes growth.
Checklist
Check root bound, prepare new pot, use fresh soil, water lightly after.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, avoid leaf wetting.
How to Apply Water Properly
Water directly at the root zone, allow water to penetrate deeply, ensure excess drains away, and water in the morning to reduce evaporation.
Watering Schedule Tips
Water when the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite for aeration, use organic matter for fertility, ensure pH balance.
Temperature Stress Management
Signs of Temperature Issues
Leaf yellowing, wilting, or bud drop; stunted growth in extreme conditions.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage.
Solution: Move to a warmer spot, insulate pots, and avoid cold drafts.
Hot Stress
Leaf scorch, wilting, and dehydration despite soil moisture.
Solution: Provide shade, increase humidity, and water early in the day.
Fertilizing Guide
Fertilizing Checklist
Check season, dilute correctly, apply to soil, avoid foliage contact.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season; cease in winter.
