Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate some direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate gradually to direct light; protect from intense sun to prevent scorching; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to full sun
Rotate plant for even growth; use sheer curtains to filter strong light; avoid direct afternoon sun.
Watering
every 7–10 days during growing season, reduce in winter
Water deeply to encourage root growth; allow soil to dry between waterings; avoid overwatering.
Soil
well-draining, loamy soil with organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix that doesn’t compact; ensure pots have drainage holes; avoid heavy clay soils.
Temperature
Prefers 65–85°F (18–29°C); tolerates brief dips to 50°F (10°C) but thrives in warm, stable conditions.
Avoid sudden temperature changes; protect from drafts; maintain stable warmth for best growth.
Fertilizing
every 4–6 weeks during active growth
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid overfertilizing.
Propagation
Methods
Stem cuttings or air layering; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Select healthy stem.
- Cut below a node.
- Apply rooting hormone.
- Plant in medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%); warm temperatures (75–85°F or 24–29°C); indirect light.
Medium
Well-draining mix of peat, perlite, and sand; can also use sphagnum moss for air layering.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots may develop in 4–8 weeks; establishment can take several months.
Tools Needed
Pruning shears, rooting hormone, plastic bag or propagator, misting bottle.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Use clean cuts just above a leaf node or branch junction; remove crossing or crowded branches.
Pruning Plan
Shape the plant; remove dead or diseased growth; encourage bushier growth; maintain size.
Tools
Pruning shears, sterilizing solution, gloves.
Checklist
Sterilize tools; prune during dormancy; remove dead/diseased parts; shape evenly.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage.
Method
Remove plant gently; trim roots if needed; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil health.
Checklist
Check root bound status; prepare new pot; use fresh soil mix; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; adjust for season.
How to Apply Water Properly
Water directly at the root zone until water drains from the bottom; ensure even moisture without waterlogging; water in the morning to reduce evaporation.
Watering Schedule Tips
Water thoroughly when the top 1–2 inches of soil are dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves (cold stress); leaf drop or wilting (heat stress); stunted growth.
Cold Stress
Slows growth; may cause leaf drop; roots become susceptible to rot in cold, wet soil.
Solution: Move to a warmer location; protect from drafts; reduce watering in cool conditions.
Hot Stress
Wilting; leaf scorch; reduced vigor; may drop leaves to conserve water.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; 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 growing season (spring–summer); cease in fall–winter.
