Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to partial shade in intense summer sun.
Sunlight Tolerance Tips:
Gradually acclimate to brighter light; protect from direct midday sun; place in east-facing windows for ideal light.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to full shade
Avoid direct afternoon sun; rotate plant for even growth; use sheer curtains to filter intense light.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure proper drainage; adjust based on season and growth stage.
Soil
well-drained, acidic, peaty soil
pH: 5.5–6.5 (slightly acidic).
Ensure soil doesn’t stay wet; test pH periodically; amend with organic matter annually.
Temperature
Prefers 60–75°F (15–24°C); cooler temperatures (50–60°F or 10–15°C) during dormancy in winter.
Protect from frost; maintain stable temperatures; avoid placing near heating/cooling vents.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid over-fertilizing.
Propagation
Methods
Stem cuttings in spring or early summer.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, remove lower leaves, apply rooting hormone, plant in medium, keep moist and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity, indirect light, and consistent warmth (65–75°F or 18–24°C).
Medium
Well-draining mix of peat and perlite or cactus mix.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots in 4–8 weeks; establish in 3–6 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a plastic bag; avoid direct sun during rooting.
Pruning & Repotting
Pruning Guide
Method
Selective thinning and heading back to maintain form.
Pruning Plan
Shape the plant, encourage bushier growth, and remove dead or weak stems.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Disinfect tools, prune during dormancy, remove dead wood, shape evenly.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
One size up (e.g., from 4-inch to 6-inch pot); ensure good drainage.
Method
Remove plant gently, trim roots if necessary, place in a slightly larger pot with fresh soil, water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil freshness.
Checklist
Check root bound status, prepare new pot, trim roots, use fresh soil, water sparingly post-repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water thoroughly when the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate peat moss for acidity; use compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, yellowing, or stunted growth; buds may fail to open in extreme conditions.
Cold Stress
Slows growth and can cause leaf drop; prolonged cold may lead to root damage.
Solution: Move to a warmer location; insulate pots; avoid cold drafts and sudden temperature drops.
Hot Stress
Wilting, leaf scorch, or reduced flowering; excessive heat can stress the plant.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth stage, dilute fertilizer, apply to moist soil, stop in dormant season.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during spring and summer; cease in fall and winter.
