Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate gradually to intense light to avoid scorching; place in a spot with filtered sunlight if outdoors, or near an east-facing window indoors.
Care Requirements
Care Difficulty
very easyeasy
Sunlight
partial shade to full sun
Rotate plant for even growth; avoid direct afternoon sun; adjust light exposure seasonally.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains, avoid letting the plant sit in water, and adjust frequency based on season and growth stage.
Soil
well-draining, sandy loam with moderate organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; test pH if issues arise.
Temperature
Prefers 65–80°F (18–27°C); thrives in warm, humid conditions with slight cooling in winter.
Avoid sudden temperature changes; maintain consistent warmth; protect from cold drafts.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; use a balanced formula.
Propagation
Methods
Stem cuttings in water or moist 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 conditions 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 may take 1–2 months.
Tools Needed
Sharp scissors, rooting hormone (optional), small pots or jars.
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 to promote branching.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or leggy growth.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sanitize tools, prune dead/leggy stems, shape the plant, dispose of clippings.
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 outgrow the pot to refresh soil and provide space.
Checklist
Check root bound status, prepare new pot, trim roots, use fresh soil, water lightly.
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 the soil is evenly moist but not waterlogged, allow excess water to drain, and water in the morning to reduce evaporation.
Watering Schedule Tips
Water when the top inch of soil is 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, or stunted growth in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf drop, and increases susceptibility to root rot due to reduced water uptake.
Solution: Move to a warmer location, protect from drafts, and reduce watering in cold conditions.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to excessive water loss.
Solution: Provide shade during peak heat, increase humidity, and water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth stage, dilute fertilizer, apply to moist soil, avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring and summer); avoid fertilizing in winter.
