Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to morning sun and afternoon shade in summer.
Sunlight Tolerance Tips:
Acclimate gradually to direct sun to avoid scorching; place in filtered light outdoors; shield from intense midday sun.
Care Requirements
Care Difficulty
easyeasy
Sunlight
bright, indirect light; tolerates partial shade
Rotate plant weekly for even growth; use sheer curtains to filter harsh light; avoid prolonged direct sun.
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 wetting foliage to prevent fungal issues.
Soil
well-draining, fertile potting mix with added 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
Ideal range 65–80°F (18–27°C); prefers stable temperatures, avoid drafts or sudden fluctuations.
Avoid placing near vents or windows with extreme temperature changes; maintain consistent room temperature.
Fertilizing
every 2–4 weeks during active growth (spring and summer), with a balanced liquid fertilizer diluted to half strength
Dilute fertilizer to prevent burn; fertilize after watering to avoid root shock; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings in water or soil.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings, remove lower leaves, dip in hormone (optional), plant in medium, maintain moisture.
Best Time: Spring or early summer when growth is active.
Environment
High humidity, indirect light, and warm temperatures (70–75°F).
Medium
Well-draining soil mix or water with occasional root hormone application.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 2–4 weeks; new growth in 6–8 weeks.
Tools Needed
Pruners, rooting hormone, small pots, water or soil medium.
Quick Tips
Use healthy, non-flowering stems; change water weekly if using water propagation; maintain consistent warmth.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node to encourage branching.
Pruning Plan
Regular pruning to maintain shape, encourage bushiness, and remove leggy growth.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sanitize tools, prune during active growth, remove dead/damaged leaves, shape evenly.
Repotting Guide
Best Season
Spring, before new growth begins.
Pot Size
Increase pot size by 1–2 inches in diameter.
Method
Remove plant gently, trim roots if needed, place in new pot with fresh soil, water lightly.
Suggestions
Repot every 1–2 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 mix, water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, avoid wetting leaves.
How to Apply Water Properly
Water directly at the root zone, ensure even moisture distribution, allow excess water to drain completely, water in the morning to reduce evaporation and fungal risk.
Watering Schedule Tips
Water when the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate organic matter like compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, wilting, yellowing, or stunted growth due to extreme cold or heat.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage in prolonged cold.
Solution: Move to a warmer location, insulate pots, avoid cold drafts, use grow lights if needed.
Hot Stress
Leaf scorch, wilting, and dehydration due to excessive heat and dry air.
Solution: Provide shade, increase humidity, water more frequently, use shade cloth outdoors.
Fertilizing Guide
Fertilizing Checklist
Check season, dilute fertilizer, water before feeding, avoid over-fertilization.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
