Care Details
Ideal Sunlight Coverage:
Bright, indirect light for 6–8 hours daily; tolerates some direct morning sun but prefers filtered light.
Sunlight Tolerance Tips:
Acclimate gradually to direct light; protect from harsh afternoon sun; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even light exposure; use sheer curtains to filter intense light; avoid drafty windows.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly until it drains from the bottom; allow soil to dry between waterings; avoid overwatering.
Soil
well-draining, fertile soil with organic matter
pH: Slightly acidic to neutral (pH 5.5–7.0)
Ensure pots have drainage holes; avoid heavy clay soils; topdress with compost annually
Temperature
Prefers 65–75°F (18–24°C); tolerates 50–85°F (10–29°C); avoid sudden temperature fluctuations.
Protect from frost; maintain consistent room temperature; avoid placing near heating/cooling vents.
Fertilizing
every 2–3 months during growing season with balanced liquid fertilizer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid overfertilizing.
Propagation
Methods
Stem cuttings
Step-by-Step Propagation Guide
- Select healthy stem.
- Cut below node.
- Apply hormone.
- Plant in medium.
- Maintain humidity.
Best Time: Spring or early summer when growth is active
Environment
High humidity (70–80%), warm (70–75°F), indirect light
Medium
Well-draining mix of perlite and peat moss
Hormone
Recommended to use rooting hormone for better success
Timeline
Roots in 4–8 weeks; establish in 3–6 months
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray
Quick Tips
Use non-flowering stems; keep consistently moist; provide bottom heat for faster rooting
Pruning & Repotting
Pruning Guide
Method
Selective cutting of stems; pinch tips for bushier growth
Pruning Plan
Remove dead/damaged growth; shape plant; encourage bushier growth
Tools
Pruning shears, sterilized knife
Checklist
Sterilize tools; prune in active growth; remove deadwood; shape evenly
Repotting Guide
Best Season
Spring before new growth begins
Pot Size
One size larger pot; ensure 1–2 inch gap from roots
Method
Remove gently; trim roots if needed; use fresh soil; ensure drainage
Suggestions
Repot every 2–3 years or when roots fill the pot; use fresh, well-draining soil
Checklist
Check root bound status; prepare new pot; use fresh soil; 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, ensuring even saturation; water early in the day to minimize evaporation; ensure excess water drains away.
Watering Schedule Tips
Water deeply once 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 organic matter for fertility
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, leaf drop, stunted growth, or browning leaf edges.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage in prolonged cold.
Solution: Move to a warmer location; insulate roots with mulch; avoid cold drafts.
Hot Stress
Wilting, leaf scorch, or premature leaf drop due to excessive heat and dryness.
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; rinse between feedings.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
