Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter strong light; avoid south-facing windows in summer.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom, allow soil to dry between waterings, avoid wetting foliage.
Soil
well-draining, sandy loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix with good drainage; avoid heavy clay soils; top-dress with compost occasionally.
Temperature
Prefers 65–85°F (18–29°C); tolerates mild fluctuations but avoid prolonged exposure to extremes.
Avoid placing near drafty windows; use a humidifier in dry heat; monitor temperature during seasonal changes.
Fertilizing
every 4–6 weeks during growing season
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup; avoid over-fertilizing.
Propagation
Methods
Stem cuttings in water or soil.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, remove lower leaves, place in medium, keep moist, wait for roots.
Best Time: Spring or early summer when plant is actively growing.
Environment
Warm, humid environment with indirect light.
Medium
Well-draining soil mix or water with occasional root hormone application.
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), small pots or jar, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; change water regularly if using water propagation.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Remove dead or leggy growth to encourage bushier, healthier plants.
Tools
Clean, sharp pruners or scissors.
Checklist
Sanitize tools, prune dead/leggy growth, make clean cuts, dispose of clippings, monitor plant response.
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; promotes fresh soil and root health.
Checklist
Select appropriate pot, prepare new soil, handle roots carefully, water after repotting, place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid wetting leaves, adjust for season.
How to Apply Water Properly
Water directly at the root zone, ensure water penetrates deeply, allow excess to drain, water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply once 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 for fertility, ensure proper aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, yellowing, or stunted growth.
Cold Stress
Slows growth, may cause leaf discoloration or drop; prolonged cold can lead to root damage.
Solution: Move to a warmer location, insulate pots, avoid cold drafts, reduce watering in cool conditions.
Hot Stress
Leaf scorch, wilting, or drooping; may drop leaves to conserve water.
Solution: Provide shade, increase humidity, water more frequently, ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer, apply during growing season, flush soil periodically, stop in winter.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
