Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate new plants gradually to direct sun; protect from intense midday sun in hot climates; ensure adequate light indoors if grown as a container plant.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant for even growth; use sheer curtains to filter intense light; place near south-facing window indoors.
Watering
every 7–14 days during active growth, less frequently in winter
Water thoroughly until runoff, ensure good drainage, and adjust frequency based on season and soil moisture.
Soil
well-drained, loamy soil
pH: Slightly alkaline to neutral (pH 6.5–7.5).
Avoid heavy clay soils; amend with organic matter; ensure pots have drainage holes.
Temperature
Hardy in USDA zones 7–9; tolerates temperatures between -12°C to 38°C; prefers warm, dry conditions.
Protect from frost; avoid sudden temperature fluctuations; ensure good air circulation.
Fertilizing
every 2–3 months during spring and summer
Fertilize in spring before new growth; use half-strength liquid fertilizer for container plants; stop fertilizing in fall.
Propagation
Methods
Stem cuttings or seed; stem cuttings are more reliable for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Late spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain temperatures around 20–25°C.
Medium
Well-draining potting mix with perlite or sand; can also use a rooting medium like peat moss.
Hormone
Recommended to use rooting hormone to improve success rates.
Timeline
Roots may develop in 4–8 weeks; establishment may take an additional 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium, plastic wrap or propagator.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity; avoid direct sunlight during rooting.
Pruning & Repotting
Pruning Guide
Method
Selective thinning, heading back, and removal of crossing or weak branches.
Pruning Plan
Prune to maintain shape, remove dead or diseased wood, and encourage healthy growth; focus on structural improvement.
Tools
Pruning shears, loppers, saw (for larger branches), disinfectant.
Checklist
Disinfect tools; prune during dormancy; remove dead/diseased wood; shape the canopy; avoid over-pruning.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
Increase pot size by 2–5 cm (1–2 inches) in diameter.
Method
Remove plant gently; trim roots if crowded; place in a slightly larger pot with fresh, well-draining soil; water thoroughly.
Suggestions
Repot every 2–3 years or when roots fill the container; beneficial for container-grown plants to refresh soil and provide space.
Checklist
Choose appropriate pot size; prepare fresh soil mix; trim roots if needed; water after repotting; place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure drainage; adjust for season; avoid overhead watering.
How to Apply Water Properly
Water directly at the root zone, apply slowly to avoid runoff, ensure water penetrates deeply to encourage deep roots, water in the morning to reduce evaporation, and ensure excess water drains away.
Watering Schedule Tips
Water deeply once every 7–10 days during spring and summer; reduce frequency to every 2–3 weeks in fall and winter, allowing soil to dry partially between waterings.
Soil Improvement
Add compost or well-rotted manure for fertility; mix in sand or perlite for drainage; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Leaf scorch or wilting in excessive heat; leaf drop or stunted growth in cold stress.
Cold Stress
Leaves may turn yellow or brown; growth slows or halts; may experience dieback in severe cold.
Solution: Provide wind protection; apply mulch to insulate roots; move container plants indoors or to a sheltered location.
Hot Stress
Leaves may wilt, scorch, or drop; soil dries out quickly; growth may slow.
Solution: Water deeply and more frequently; provide afternoon shade; use mulch to retain moisture.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in spring; follow dilution instructions; avoid winter feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring; apply a diluted liquid fertilizer monthly during growing season; avoid fertilizing in winter.
