Care Details
Ideal Sunlight Coverage:
Full sun to partial shade (4–6 hours of direct sunlight daily). Tolerates light shade but may produce fewer flowers.
Sunlight Tolerance Tips:
Acclimate the plant gradually if moving from shade to sun; protect from intense midday sun in hot climates; ensure good air circulation to prevent sunburn.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Morning sun is preferable; avoid harsh afternoon sun in summer; adjust placement based on seasonal light changes.
Watering
every 7–10 days during active growth, less frequently in winter
Water deeply but infrequently to encourage deep root growth; avoid overwatering, especially in winter; adjust frequency based on weather and soil conditions.
Soil
well-draining, moderately fertile soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil dries between waterings; avoid heavy clay soils; amend with organic matter for better structure.
Temperature
Hardy in USDA zones 6–9. Prefers cool winters (down to -20°C/-4°F) and moderate summers (up to 30°C/86°F).
Protect from late frosts in spring; ensure winter dormancy for best flowering; avoid sudden temperature fluctuations.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize sparingly to avoid excessive growth; focus on phosphorus for flowering; stop fertilizing before winter dormancy.
Propagation
Methods
Stem cuttings taken in late spring or early summer.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Maintain humidity.
- Wait for roots.
Best Time: Late spring to early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (18–24°C/65–75°F), and indirect light.
Medium
Peat-based potting mix with added perlite or sand for drainage.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots typically develop in 4–8 weeks; establishment may take an additional 1–2 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic bags or propagator, misting bottle.
Quick Tips
Use semi-hardwood cuttings; maintain consistent moisture; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Selective pruning of older stems and deadwood; thin out crowded areas to improve air circulation.
Pruning Plan
Prune to shape the plant, encourage flowering, and remove dead or weak growth. Best done after flowering in late winter or early spring.
Tools
Pruning shears, loppers, gloves, disinfectant.
Checklist
Disinfect tools; prune after flowering; remove dead or crossing branches; shape as desired.
Repotting Guide
Best Season
Early spring, before new growth begins.
Pot Size
Increase pot size by 2–5 cm (1–2 inches) in diameter.
Method
Remove the plant carefully; trim any circling roots; repot in fresh, well-draining soil; water thoroughly.
Suggestions
Repot only if the plant becomes root-bound or outgrows its container. Generally, repotting every 2–3 years is sufficient.
Checklist
Choose appropriate pot; prepare fresh soil; trim roots if needed; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone. Water until it drains from the bottom, but avoid waterlogging. Early morning or late evening watering is ideal to minimize evaporation.
Watering Schedule Tips
Water moderately during spring and summer, allowing the top inch of soil to dry between waterings. Reduce watering in fall and winter, only providing enough to prevent the soil from completely drying out.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, yellowing, or stunted growth in extreme heat; dieback or delayed flowering in insufficient cold exposure.
Cold Stress
The plant can tolerate severe cold but may experience dieback if not properly hardened off or if roots are not insulated.
Solution: Mulch heavily around the base in winter; protect roots from frost; ensure good air circulation to prevent fungal issues.
Hot Stress
Excessive heat can cause leaf scorch, wilting, or reduced flowering, especially if combined with drought stress.
Solution: Provide partial shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in spring; dilute liquid fertilizer; avoid winter feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring. Apply a diluted liquid fertilizer monthly during the growing season (spring to summer). Avoid fertilizing in fall and winter.
