Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate gradually to intense light to avoid scorching; place in a spot with filtered sunlight if outdoors; indoors, place near an east or west-facing window.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; avoid direct midday sun; adjust light exposure seasonally.
Watering
every 5–7 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom, allow soil to dry between waterings, avoid wetting foliage to prevent fungal issues.
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 compacted soil; refresh soil every 1–2 years.
Temperature
Prefers warm conditions, ideal range 65–85°F (18–29°C); sensitive to cold drafts and frost.
Avoid placing near air vents or drafty windows; monitor temperature changes; adjust watering based on heat levels.
Fertilizing
every 4–6 weeks during growing season
Always water before fertilizing to prevent root burn; flush soil occasionally to prevent salt buildup; stop fertilizing in winter.
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, and wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light.
Medium
Well-draining soil mix or water with occasional changes.
Hormone
Optional but can speed up rooting.
Timeline
Roots typically form in 2–4 weeks; new growth may take 4–6 weeks.
Tools Needed
Pruning shears, rooting hormone (optional), small pots or jars, misting bottle.
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; maintain consistent moisture.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased parts.
Tools
Clean pruning shears or scissors.
Checklist
Sanitize tools, prune during active growth, remove dead/diseased parts, shape evenly, clean up debris.
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 needed, place in a new pot with fresh soil, water lightly.
Suggestions
Repot every 1–2 years or when roots fill the pot; beneficial for growth and soil freshness.
Checklist
Choose new pot, prepare fresh soil, inspect roots, prune if necessary, water lightly, place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, avoid wetting leaves, discard excess water.
How to Apply Water Properly
Water directly at the root zone, apply until water drains from the bottom, ensure excess water is removed to prevent waterlogging, water in the morning to allow foliage to dry.
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 to improve drainage; incorporate organic matter like compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, wilting, stunted growth, or leaf drop in cold; scorching or leaf burn in excessive heat.
Cold Stress
Low temperatures slow growth, cause leaf discoloration, and may lead to root rot if soil remains wet.
Solution: Move plant to a warmer location, protect from drafts, reduce watering, and ensure good air circulation.
Hot Stress
Excessive heat can cause leaf scorch, wilting, and dehydration, especially if combined with low humidity.
Solution: Provide shade during peak heat, increase humidity with misting or a humidifier, and water more frequently if soil dries out quickly.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply to moist soil, avoid foliage contact, flush periodically.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during the growing season (spring and summer); avoid fertilizing in fall and winter.
