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.
Soil
well-draining, fertile potting mix with added organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; topdress with compost annually.
Temperature
Prefers 65–85°F (18–29°C); cooler temperatures in winter (55–60°F or 13–15°C) can promote dormancy.
Avoid sudden temperature changes; protect from drafts; maintain consistent indoor temperatures.
Fertilizing
every 4–6 weeks during active growth (spring and summer)
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup; avoid overfertilizing.
Propagation
Methods
Stem cuttings in spring or early summer.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, remove lower leaves, apply rooting hormone, plant in medium, maintain humidity, and wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (70–75°F or 21–24°C), and indirect light.
Medium
Well-draining potting mix with perlite or sand.
Hormone
Rooting hormone is recommended to speed up root development.
Timeline
Roots typically develop in 4–6 weeks; new growth may take 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic bags or propagator, misting bottle.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth; cut just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or leggy stems.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sanitize tools, prune dead/damaged growth, shape the plant, remove crossing branches, clean up debris.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
Increase pot size by 2–3 inches in diameter; avoid oversized pots.
Method
Use fresh potting mix, ensure good drainage, gently tease out crowded roots, and water thoroughly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil freshness.
Checklist
Choose new pot, prepare soil mix, inspect roots, position plant correctly, water and place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, 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 like compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, leaf drop, stunted growth, or bud drop due to extreme heat or cold.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage if temperatures drop below 50°F (10°C).
Solution: Move to a warmer location, insulate pots, avoid cold drafts, and protect from frost.
Hot Stress
Wilting, leaf scorch, and reduced flowering due to prolonged exposure to temperatures above 90°F (32°C).
Solution: Provide shade, increase humidity, water more frequently, and ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply during growing season, monitor for signs of overfertilization.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); reduce or stop in fall/winter.
