Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate some direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate gradually to direct light, protect from intense midday sun, adjust placement based on seasonal light changes.
Care Requirements
Care Difficulty
moderateeasy
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter intense light; move outdoors in spring/summer for stronger light.
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, loamy soil with moderate organic content
pH: Slightly acidic to neutral (6.0–7.0).
Use a mix with good drainage; avoid heavy clay soils; topdress with compost annually.
Temperature
Prefers 65–85°F (18–29°C); tolerates mild fluctuations but avoid prolonged exposure to extremes.
Avoid placing near drafty windows; use a thermometer to monitor; adjust care based on seasonal changes.
Fertilizing
every 4–6 weeks during growing season
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup; adjust frequency based on growth rate.
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 the plant is actively growing.
Environment
Warm, humid, and bright indirect light.
Medium
Well-draining soil mix or water with occasional changes.
Hormone
Optional but can speed up rooting.
Timeline
Roots in 2–4 weeks; establish in 6–8 weeks.
Tools Needed
Pruners, rooting hormone (optional), container, water or soil medium.
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; maintain consistent moisture.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a leaf node or bud, thin out crowded areas.
Pruning Plan
Remove dead or overgrown stems to encourage bushier growth and better fruiting.
Tools
Clean pruners or scissors, disinfectant.
Checklist
Sanitize tools, prune dead/damaged growth, shape plant, clean up debris.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size up (e.g., from 4-inch to 6-inch pot).
Method
Use fresh well-draining soil, trim rootbound roots, place in a slightly larger pot.
Suggestions
Repot every 2–3 years or when roots outgrow the pot; beneficial for growth and fruiting.
Checklist
Prepare new pot, trim roots if needed, use fresh soil, water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid wetting leaves.
How to Apply Water Properly
Water directly at the root zone, ensure even saturation, allow excess water 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 compost for fertility, ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, yellowing, or stunted growth.
Cold Stress
Slows growth, may cause leaf discoloration or dieback in temperatures below 50°F (10°C).
Solution: Move to a warmer location, insulate pots, avoid cold drafts, use a space heater if necessary.
Hot Stress
Leaf scorch, wilting, or reduced flowering in temperatures above 90°F (32°C).
Solution: Provide shade, increase humidity, water more frequently, use shade cloth outdoors.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply during active growth, 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.
