Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily. Direct sunlight should be avoided, especially in summer. Adjust light exposure gradually when moving the plant.
Sunlight Tolerance Tips:
Acclimate the plant to new light conditions over 1–2 weeks; avoid direct midday sun to prevent leaf burn; place in east-facing windows or shaded outdoor spots.
Care Requirements
Care Difficulty
challengingmoderate
Sunlight
bright, indirect light
Rotate plant weekly for even light; use sheer curtains to filter intense sun; monitor for signs of sunburn.
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; reduce frequency in winter dormancy.
Soil
well-draining orchid mix with bark, sphagnum moss, and perlite
pH: Slightly acidic, 5.5–6.5.
Use orchid-specific mix; avoid heavy garden soils; ensure pots have drainage holes.
Temperature
Prefers 60–75°F (15–24°C) during the day and 50–60°F (10–15°C) at night. A 10–15°F drop in winter encourages blooming.
Maintain stable temperatures; provide a winter cool period; avoid placing near heating/cooling vents.
Fertilizing
every 2 weeks during active growth (spring to autumn) 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
Division of pseudobulbs or backbulbs. Mature plants can be split into smaller clumps, each with 3–4 pseudobulbs.
Step-by-Step Propagation Guide
- Separate pseudobulbs with sharp, sterile tools.
- Pot in orchid mix.
- Water lightly.
- Maintain humidity.
Best Time: After flowering, in late spring or early summer when new growth begins.
Environment
High humidity (70–80%), warm temperatures (65–75°F/18–24°C), and bright indirect light.
Medium
Fine orchid bark mix or sphagnum moss with perlite for drainage.
Hormone
Rooting hormone is optional but can aid in establishing backbulbs.
Timeline
Backbulbs may take 6–12 months to develop roots; established divisions can rebloom in 1–2 years.
Tools Needed
Sterile knife, orchid mix, rooting hormone (optional), humidity dome.
Quick Tips
Ensure each division has viable pseudobulbs; keep new plants shaded initially; maintain consistent moisture.
Pruning & Repotting
Pruning Guide
Method
Cut flower spikes at the base; trim dead pseudobulbs with sterile shears.
Pruning Plan
Remove spent flower spikes and dead or damaged pseudobulbs to redirect energy to new growth and blooms.
Tools
Sterile pruning shears or scissors.
Checklist
Use sterile tools; cut dead/damaged parts; avoid over-pruning healthy growth.
Repotting Guide
Best Season
Late spring or early summer, after flowering and before new growth begins.
Pot Size
One size larger pot (e.g., +2–3 cm in diameter) with good drainage holes.
Method
Remove old mix, trim dead roots, place in a slightly larger pot with fresh orchid mix, and ensure good drainage.
Suggestions
Repot every 2–3 years or when the potting mix breaks down or roots outgrow the container.
Checklist
Clean roots; use fresh orchid mix; ensure drainage; avoid over-potting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water early morning; ensure drainage; 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 and avoid wetting the pseudobulbs excessively. Allow excess water to drain completely.
Watering Schedule Tips
Water thoroughly when the top inch of soil feels dry, typically every 7–10 days during active growth (spring/summer) and 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; use sphagnum moss for moisture retention.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis, bud drop, stunted growth, or leaf spotting. Cold stress may cause water-soaked leaf spots.
Cold Stress
Low temperatures slow metabolic processes, leading to root damage and reduced nutrient uptake, especially below 50°F (10°C).
Solution: Move to a warmer location; insulate pots; avoid cold drafts; maintain consistent temperatures above 50°F (10°C).
Hot Stress
Excessive heat (above 85°F/29°C) can cause dehydration, wilting, and flower bud abortion, especially with low humidity.
Solution: Increase humidity with misting or pebble trays; provide shade; ensure adequate ventilation; water more frequently if heat persists.
Fertilizing Guide
Fertilizing Checklist
Use diluted orchid fertilizer; fertilize during active growth; flush periodically.
Fertilizing Method
Use a balanced orchid fertilizer (20-20-20) diluted to half strength every 2–4 weeks during active growth (spring/summer). Reduce or stop fertilizing in fall/winter.
