Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight, protect from harsh midday sun, and ensure adequate ventilation to prevent scorching.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant for even light exposure; use shade cloth in extreme heat.
Watering
every 7–10 days during dry periods, more frequently in extreme heat
Water thoroughly until runoff, ensure good drainage, and avoid waterlogging.
Soil
sandy, well-draining soil with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils.
Temperature
Thrives in warm climates (20–30°C); tolerates brief dips to 10°C but prefers stable warmth.
Avoid sudden temperature changes; use fans for airflow in hot weather.
Fertilizing
every 3–4 months with slow-release fertilizer during active growth
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or seeds.
Step-by-Step Propagation Guide
- Take cuttings, apply hormone, place in medium, maintain humidity, and wait for roots.
Best Time: Spring or early summer when growth is active.
Environment
High humidity (70–80%), indirect light, and warm temperatures (24–28°C).
Medium
Well-draining mix of peat, perlite, and sand.
Hormone
Rooting hormone recommended for faster rooting.
Timeline
Roots in 4–8 weeks; establish in 3–6 months.
Tools Needed
Pruners, rooting hormone, propagation tray, humidity dome.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture.
Pruning & Repotting
Pruning Guide
Method
Selective cutting of branches to open canopy or reduce height.
Pruning Plan
Shape plant, remove dead/diseased growth, and encourage bushier form.
Tools
Pruning shears, loppers, gloves.
Checklist
Sterilize tools, prune during dormancy, remove dead wood, shape evenly.
Repotting Guide
Best Season
Spring before new growth begins.
Pot Size
Increase pot size by 2–5 cm in diameter.
Method
Use fresh well-draining soil, trim roots if pot-bound, ensure drainage holes are clear.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth.
Checklist
Check root bound status, prepare new pot, trim roots, use fresh soil, water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, observe plant response.
How to Apply Water Properly
Water at the root zone, apply slowly to avoid runoff, ensure water penetrates deeply, water in the morning to reduce evaporation, and ensure proper drainage.
Watering Schedule Tips
Water deeply once or twice a week during dry periods, allowing the soil to dry slightly between waterings. Adjust frequency based on rainfall and temperature; reduce in cooler months.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, yellowing, stunted growth, or wilting in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf drop or dieback in prolonged cold.
Solution: Protect from frost, provide windbreaks, and use mulch to insulate roots.
Hot Stress
Wilting, leaf scorch, or reduced flowering in excessive heat.
Solution: Provide shade during peak heat, increase humidity, and water deeply.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply during active growth, avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid winter fertilization.
