Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; tolerates partial shade but may stretch in low light.
Sunlight Tolerance Tips:
Acclimate gradually to intense light to prevent scorching; place in filtered sunlight outdoors or near an east-facing window indoors.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Rotate plant for even growth; avoid direct midday sun; adjust light exposure seasonally.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but allow soil to dry between waterings; avoid overwatering, especially in winter.
Soil
well-draining, loamy soil with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; top-dress with compost annually.
Temperature
Prefers 65–85°F (18–29°C); thrives in warm, stable conditions with slight cooling in winter.
Avoid drafts; maintain stable temperatures; protect from extreme fluctuations.
Fertilizing
every 4–6 weeks during growing season
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings in water or soil.
Step-by-Step Propagation Guide
- Select healthy stem.
- Cut below node.
- Remove lower leaves.
- Place in medium.
- Maintain moisture.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid, and bright indirect light with protection from direct sun.
Medium
Well-draining potting mix or water with occasional nutrient additions.
Hormone
Optional but can speed up rooting.
Timeline
Roots typically form in 2–4 weeks; new growth in 6–8 weeks.
Tools Needed
Pruners, rooting hormone (optional), pot, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; keep consistently moist but not waterlogged.
Pruning & Repotting
Pruning Guide
Method
Pinch back stems or cut just above a leaf node to promote branching.
Pruning Plan
Remove dead or leggy growth to encourage bushier, healthier plants.
Tools
Clean, sharp pruners or scissors.
Checklist
Sanitize tools; prune dead/leggy stems; shape for airflow; dispose of clippings.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Choose a pot 1–2 inches larger in diameter than the current one.
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 outgrow the pot to refresh soil and provide space.
Checklist
Check root bound status; prepare new pot with drainage; 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 at the base of the plant, ensuring even moisture reaches the root zone; allow excess water to drain completely to prevent waterlogging.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate organic matter for fertility.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves (cold stress), wilting or leaf drop (heat stress), stunted growth.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage in prolonged cold.
Solution: Move to a warmer location, insulate pots, and reduce watering in cold periods.
Hot Stress
Leaves may scorch, wilt, or drop; growth may cease in extreme heat.
Solution: Provide shade, increase humidity, and water more frequently during heatwaves.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
