Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily. Can tolerate direct morning sun but should be protected from harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate plants gradually to direct light to prevent scorching. Indoors, place near east-facing windows; outdoors, provide dappled shade during peak sun hours.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid placing in drafty areas.
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; avoid overwatering, which can cause root rot; ensure water reaches the root zone.
Soil
well-draining orchid mix with bark and perlite
pH: Slightly acidic, pH 5.5–6.5.
Ensure pots have drainage holes; avoid heavy potting mixes; repot if medium becomes compacted.
Temperature
Prefers warm temperatures between 65–85°F (18–29°C). Can tolerate brief drops to 50°F (10°C) but thrives in stable warmth.
Avoid sudden temperature fluctuations; maintain consistent warmth; protect from cold drafts.
Fertilizing
every 2 weeks during active growth with diluted orchid fertilizer, none in winter
Flush soil periodically to prevent salt buildup; fertilize after watering to avoid root burn; adjust frequency based on growth rate.
Propagation
Methods
Stem cuttings or division of pseudobulbs. Stem cuttings are the most common method for home growers.
Step-by-Step Propagation Guide
- Select a healthy stem.
- Cut below a node.
- Apply rooting hormone if using.
- Plant in medium.
- Maintain humidity and warmth.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (75–85°F), 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 typically form in 4–8 weeks; new growth may take 3–6 months.
Tools Needed
Sharp scissors, rooting hormone, propagation tray, humidity dome.
Quick Tips
Keep cuttings moist but not waterlogged; provide bottom heat for faster rooting; avoid direct sunlight.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim pseudobulbs just above the next healthy node.
Pruning Plan
Remove spent flower spikes and dead or damaged pseudobulbs to encourage new growth and maintain plant health.
Tools
Sterile pruning shears or scissors, disinfectant.
Checklist
Disinfect tools; cut at a 45-degree angle; remove only dead/damaged parts; clean up debris.
Repotting Guide
Best Season
Spring, just before the start of the growing season.
Pot Size
One size larger pot, ensuring good drainage holes.
Method
Remove plant gently; trim dead roots; place in a slightly larger pot with fresh orchid mix; water lightly after repotting.
Suggestions
Repot every 2–3 years or when the potting medium breaks down. Necessary to refresh nutrients and improve drainage.
Checklist
Prepare new pot; sterilize tools; trim roots; use fresh mix; water sparingly post-repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water thoroughly; ensure proper drainage; adjust frequency with seasons.
How to Apply Water Properly
Water until it drains freely from the bottom of the pot, ensuring even moisture without waterlogging. Focus on the root zone and avoid wetting the leaves to prevent fungal issues.
Watering Schedule Tips
Water thoroughly when the top inch of soil feels dry, typically every 7–10 days in warm months and every 10–14 days in cooler months. Reduce frequency during dormancy.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate orchid bark for aeration; use charcoal to absorb toxins.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis (yellowing leaves), bud drop, or stunted growth in cold; wilting or leaf burn in excessive heat.
Cold Stress
Low temperatures slow growth and can damage roots, leading to poor nutrient uptake and increased susceptibility to disease.
Solution: Move to a warmer location; insulate pots with bubble wrap; avoid placing near drafty windows or doors.
Hot Stress
Excessive heat can cause dehydration, leaf scorch, and reduced flowering due to water stress and metabolic disruption.
Solution: Provide shade during peak heat; increase humidity with misting or a pebble tray; ensure adequate watering.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during growing season; flush periodically; avoid contact with leaves.
Fertilizing Method
Use a balanced orchid fertilizer (20-20-20) diluted to half strength every 2–4 weeks during active growth (spring and summer). Reduce or stop in fall and winter.
