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 sun to prevent scorching, adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to filtered sunlight
Rotate plant for even growth; use sheer curtains to filter intense light; move outdoors in spring/summer for stronger light.
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 overwatering especially in low light.
Soil
well-draining, fertile potting mix with added organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix with good drainage; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Prefers 65–85°F (18–29°C); thrives in warm, humid conditions; sensitive to cold drafts.
Avoid sudden temperature changes; keep away from air vents; maintain consistent warmth.
Fertilizing
every 4–6 weeks during active growth with balanced liquid fertilizer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid overfertilizing.
Propagation
Methods
Stem cuttings with at least two nodes.
Step-by-Step Propagation Guide
- Take cutting, apply rooting hormone, plant in medium, maintain humidity, wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (75–85°F), indirect light.
Medium
Well-draining mix of peat, perlite, and sand.
Hormone
Rooting hormone recommended for faster root development.
Timeline
Roots develop in 3–6 weeks; new growth appears in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic bags or propagator.
Quick Tips
Use healthy, non-flowering stems; keep consistently moist; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Selective cutting of stems to promote branching; pinch tips for bushier growth.
Pruning Plan
Shape the plant, encourage bushier growth, and remove dead or leggy stems.
Tools
Clean pruning shears, gloves.
Checklist
Sanitize tools, prune during active growth, remove dead/damaged stems, shape evenly.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Remove plant gently, trim roots if necessary, place in new pot with fresh soil, water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and 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, 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 good aeration.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, leaf drop, stunted growth, or bud drop in extreme conditions.
Cold Stress
Low temperatures slow growth, cause leaf discoloration, and may lead to root damage.
Solution: Move to a warmer location, protect from drafts, maintain humidity, and avoid overwatering.
Hot Stress
Excessive heat can cause wilting, leaf scorch, and dehydration, especially with low humidity.
Solution: Provide shade, increase humidity, water more frequently, and ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check growth phase, use diluted fertilizer, apply during growing season, flush soil periodically.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); reduce or stop in fall/winter.
