Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; tolerates some direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate slowly to brighter 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 light
Rotate plant for even growth; use sheer curtains to filter direct light; avoid placing near hot windows.
Watering
every 7–10 days during active growth, reducing to every 2–3 weeks in winter
Water deeply but infrequently; ensure proper drainage; avoid waterlogging.
Soil
well-draining, slightly acidic potting mix with peat and sand
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; topdress with compost occasionally.
Temperature
Prefers 60–75°F (15–24°C); tolerates a range but thrives in moderate temperatures.
Avoid sudden temperature changes; protect from drafts; maintain consistent room temperature.
Fertilizing
every 4–6 weeks during spring and summer with balanced liquid fertilizer, none in winter
Flush soil occasionally to prevent salt buildup; reduce feeding in dormant periods; apply fertilizer to moist soil.
Propagation
Methods
Stem cuttings or seeds; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a healthy cutting, 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 (70–90%), warm temperatures (70–75°F), and indirect light.
Medium
Well-draining mix of peat, perlite, and sand.
Hormone
Recommended to use rooting hormone for better success.
Timeline
Roots may develop in 4–8 weeks; establishment takes several months.
Tools Needed
Pruning shears, rooting hormone, propagation tray, humidity dome.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Selective pruning of branches to shape the plant; avoid cutting into old wood.
Pruning Plan
Prune to maintain shape, remove dead/damaged growth, and encourage bushier growth.
Tools
Pruning shears, sterilizing solution, gloves.
Checklist
Sterilize tools, prune selectively, remove dead growth, clean up debris.
Repotting Guide
Best Season
Spring, when the plant is entering active growth.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage.
Method
Remove plant gently, trim roots if needed, 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, 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 at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water thoroughly when the top 1–2 inches of soil are dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate organic matter for fertility.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, leaf drop, stunted growth, or browning leaf tips.
Cold Stress
Slows growth, may cause leaf discoloration or drop; prolonged cold can damage roots.
Solution: Move to a warmer location; insulate roots with mulch; avoid cold drafts.
Hot Stress
Wilting, leaf scorch, or brown leaf edges; may drop leaves to conserve water.
Solution: Provide shade, increase humidity, water more frequently, and ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check season, dilute fertilizer, apply to moist soil, flush periodically.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in fall/winter.
