Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; tolerates partial shade, especially in hot climates.
Sunlight Tolerance Tips:
Acclimate gradually to intense light to prevent scorching; protect from harsh afternoon sun; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter direct sun; move outdoors in spring/summer for stronger light.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly until runoff, allow soil to dry partially between waterings, and avoid waterlogging.
Soil
well-draining, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use raised beds for better drainage; avoid heavy clay soils; amend with organic matter annually.
Temperature
Prefers 60–75°F (15–24°C); tolerates mild frosts but thrives in moderate temperatures.
Avoid sudden temperature shifts; protect from drafts; maintain consistent room temperature indoors.
Fertilizing
every 2–3 months during spring and summer
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup; adjust based on growth rate.
Propagation
Methods
Stem cuttings or division of mature clumps.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings, remove lower leaves, dip in 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 (65–75°F), and indirect light.
Medium
Well-draining mix of peat, perlite, and sand.
Hormone
Rooting hormone is beneficial but not essential.
Timeline
Roots develop in 4–6 weeks; new growth appears in 2–3 months.
Tools Needed
Pruners, rooting hormone, small pots, humidity dome, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Selective cutting of weak or overcrowded stems to ground level.
Pruning Plan
Remove dead or damaged stems to encourage new growth and maintain shape.
Tools
Pruning shears, sterilizing solution, gloves.
Checklist
Sterilize tools, prune dead/damaged stems, shape plant, clean up debris, disinfect tools post-use.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Remove plant gently, trim roots if needed, place in new pot with fresh soil, water lightly, and avoid direct sun for a week.
Suggestions
Repot every 2–3 years or when roots fill the container to prevent overcrowding.
Checklist
Choose new pot, prepare soil mix, inspect roots, prune if needed, repot carefully, water lightly, acclimate slowly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid wetting foliage, adjust for season.
How to Apply Water Properly
Water directly at the root zone, ensuring even saturation to a depth of 6–8 inches, allowing excess water to drain freely, and watering in the morning to minimize evaporation.
Watering Schedule Tips
Water deeply once the soil surface is dry to the touch, typically every 7–10 days during active growth, reducing frequency to every 2–3 weeks in winter dormancy.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure aeration with loose texture.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf drop in excessive heat; stunted growth or browning tips in cold stress.
Cold Stress
Low temperatures slow growth and may cause root damage if below 20°F (-6°C).
Solution: Protect with frost cloth in winter; ensure good drainage to prevent root rot; move indoors if temperatures drop below 25°F (-4°C).
Hot Stress
Excessive heat can lead to wilting, leaf scorch, and reduced vigor.
Solution: Provide shade during peak sun; increase humidity with misting; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply during active growth, avoid winter feeding, flush periodically.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during spring and summer; cease in fall and winter.
