Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily. Can tolerate direct morning sun but avoid harsh afternoon sun, especially in summer.
Sunlight Tolerance Tips:
Acclimate plants gradually to direct sunlight to prevent scorching. Indoors, place near an east-facing window. Outdoors, provide dappled shade during peak sun hours.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even light exposure; use sheer curtains to filter intense sunlight; avoid placing in drafty areas.
Watering
every 7–10 days during active growth, less frequently in winter
Allow the potting medium to dry slightly between waterings; water thoroughly until water drains from the bottom; avoid waterlogging the roots.
Soil
well-draining orchid mix with bark and perlite
pH: Slightly acidic to neutral (pH 5.5–6.5).
Ensure pot has drainage holes; avoid compacted soil; refresh mix every 2–3 years.
Temperature
Prefers 60–85°F (15–29°C). Tolerates brief drops to 50°F (10°C) but thrives in warmer conditions during active growth.
Avoid sudden temperature fluctuations; maintain consistent warmth during active growth; protect from cold drafts.
Fertilizing
every 2 weeks during active growth with diluted orchid fertilizer, every 3 months in winter
Flush the pot with plain water monthly to prevent salt buildup; fertilize after watering to avoid root burn; apply in the morning for better absorption.
Propagation
Methods
Stem cuttings (keikis) or division of pseudobulbs.
Step-by-Step Propagation Guide
- Select a healthy pseudobulb.
- Cut below a node.
- Apply rooting hormone if using.
- Place in propagation medium.
- Maintain humidity and warmth.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (70–80°F or 21–27°C), and indirect light.
Medium
Fine orchid bark mix or sphagnum moss with perlite for aeration.
Hormone
Rooting hormone is optional but can speed up root development.
Timeline
Roots may develop in 4–8 weeks; establishment can take 3–6 months.
Tools Needed
Sharp sterilized scissors, rooting hormone, propagation tray, humidity dome.
Quick Tips
Keep cuttings out of direct sun; maintain consistent moisture; monitor for signs of rot.
Pruning & Repotting
Pruning Guide
Method
Cut dead pseudobulbs at the base; trim spent flower spikes just above the next node if reblooming is desired.
Pruning Plan
Focus on removing dead or damaged pseudobulbs and spent flower spikes to encourage new growth and maintain plant health.
Tools
Sterilized sharp scissors or pruning shears.
Checklist
Sterilize tools; remove dead/damaged parts; make clean cuts; clean up debris; disinfect tools after use.
Repotting Guide
Best Season
Spring, just before the start of the growing season.
Pot Size
One size larger pot (e.g., +2–3 cm in diameter) with good drainage holes.
Method
Remove the plant gently; trim dead roots; place in a slightly larger pot with fresh orchid mix; ensure good drainage; water lightly after repotting.
Suggestions
Repot every 2–3 years or when the potting medium breaks down. Necessary if roots are overcrowded or the plant is top-heavy.
Checklist
Prepare new pot with drainage; trim old roots; use fresh orchid mix; position plant correctly; water sparingly; place in shaded area for recovery.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water thoroughly; ensure proper drainage; discard excess water; water in the morning.
How to Apply Water Properly
Water directly onto the root zone, ensuring even moisture distribution. Water until excess drains from the pot, then discard any standing water. Water in the morning to allow foliage to dry before nightfall.
Watering Schedule Tips
Water every 5–7 days during active growth in spring/summer; reduce frequency to every 10–14 days in fall/winter when growth slows. Adjust based on humidity and temperature.
Soil Improvement
Add perlite or coarse sand for aeration; incorporate sphagnum moss for moisture retention; use orchid-specific fertilizer to enhance nutrient availability.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis (yellowing leaves), bud drop, stunted growth, or leaf spotting.
Cold Stress
Slows metabolic processes, reduces water uptake, and can lead to root rot if overwatered in cold conditions.
Solution: Move to a warmer location; reduce watering; provide a heat source if necessary; ensure good air circulation to prevent fungal issues.
Hot Stress
Causes wilting, leaf scorch, and dehydration, especially if combined with low humidity.
Solution: Increase humidity with misting or a humidifier; provide shade during peak heat; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during active growth; flush periodically; avoid contact with new roots.
Fertilizing Method
Use a balanced orchid fertilizer (20-20-20) diluted to half strength every 2–4 weeks during active growth. Reduce or stop fertilizing in winter.
