Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; tolerate partial shade but may stretch in low light.
Sunlight Tolerance Tips:
Acclimate gradually to intense light to prevent scorching; place near east-facing windows indoors; provide dappled light outdoors.
Care Requirements
Care Difficulty
moderateeasy
Sunlight
partial shade to full sun with protection from intense afternoon sun
Rotate plant weekly for even growth; use sheer curtains to filter direct sun; avoid south-facing windows in summer.
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 letting the plant sit in water.
Soil
well-draining, loamy soil 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
Prefers 65–75°F (18–24°C); tolerates 50–85°F (10–29°C) but thrives in moderate warmth.
Avoid sudden temperature changes; protect from drafts; maintain consistent room temperature.
Fertilizing
every 4–6 weeks during active growth (spring and summer)
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid over-fertilizing.
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
High humidity, indirect light, and warm temperatures (70–75°F or 21–24°C).
Medium
Well-draining potting mix or water with occasional root hormone application.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic wrap or propagator.
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
Encourage bushier growth and remove leggy stems; maintain shape and health.
Tools
Clean pruning shears or sharp scissors.
Checklist
Sterilize tools, prune during active growth, remove dead/damaged leaves, shape evenly.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 1–2 inches in diameter.
Method
Remove plant gently, trim roots if necessary, place in new pot with fresh soil, water lightly.
Suggestions
Repot every 1–2 years or when roots outgrow the pot; promotes fresh soil and root health.
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 thoroughly, ensure drainage, adjust for season.
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.
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
Wilting, leaf drop, stunted growth, or browning leaf edges.
Cold Stress
Slows growth, causes leaf drop, and may lead to root rot due to reduced water uptake.
Solution: Move to a warmer location, insulate pots, avoid cold drafts, and reduce watering.
Hot Stress
Leaf scorch, wilting, and dehydration due to excessive transpiration.
Solution: Provide shade, increase humidity, water more frequently, and ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check growth phase, dilute fertilizer, apply to moist soil, avoid contact with leaves.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
