Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight per day). Tolerates partial shade but may produce fewer flowers.
Sunlight Tolerance Tips:
Acclimate plants gradually if moving from shade to sun. Protect from intense midday sun in hot climates. Ensure good air circulation to prevent fungal issues in humid conditions.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun
Full sun is best; avoid deep shade; rotate pots for even growth.
Watering
every 7–10 days during active growth, less frequently in winter
Water at the base of the plant to avoid foliage wetting; ensure soil dries slightly between waterings; avoid overwatering to prevent root rot.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; avoid heavy clay; enrich with organic matter.
Temperature
Hardy in USDA zones 4–9. Prefers cool to moderate temperatures (60–75°F or 15–24°C). Tolerates cold winters and moderate heat.
Protect from extreme cold; water deeply in heat; ensure good air circulation.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize sparingly; avoid high-nitrogen formulas; apply in spring only.
Propagation
Methods
Stem cuttings or division in spring or early autumn.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early autumn when temperatures are moderate and growth is active.
Environment
Warm (65–75°F or 18–24°C), humid, and bright but indirect light.
Medium
Well-draining potting mix, such as a mix of peat, perlite, and sand.
Hormone
Optional, but rooting hormone can improve success rates.
Timeline
Roots typically form in 3–6 weeks; plants may take a full season to establish.
Tools Needed
Pruners, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; maintain humidity; avoid overwatering.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushiness; cut just above a leaf node or lateral branch.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or weak growth. Deadheading spent flowers promotes reblooming.
Tools
Clean, sharp pruners or scissors.
Checklist
Use clean tools; prune dead or weak stems; deadhead regularly; shape as needed.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter).
Method
Gently remove plant; trim any circling roots; 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. May not need frequent repotting if growth is contained.
Checklist
Choose appropriate pot size; use fresh soil; trim roots if needed; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; avoid wetting foliage; ensure drainage.
How to Apply Water Properly
Water slowly and deeply at the root zone to encourage deep root growth. Ensure water penetrates the root ball and allow excess to drain away. Water in the morning to minimize evaporation and fungal issues.
Watering Schedule Tips
Water deeply once a week during the growing season, reducing frequency in winter. Adjust based on rainfall and soil moisture retention.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf scorch in excessive heat; stunted growth or bud drop in cold stress.
Cold Stress
Leaves may wilt or turn purple; growth slows or halts. Hardy to cold but may suffer in prolonged freezing with wet soil.
Solution: Ensure well-draining soil to prevent root damage from freezing. Mulch lightly in winter to insulate roots. Protect from harsh winds.
Hot Stress
Wilting, leaf scorch, or reduced flowering during prolonged heat waves.
Solution: Provide afternoon shade if possible; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in spring; avoid late-season feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring. Avoid excessive nitrogen to prevent leggy growth. Reduce or stop fertilizing in late summer/autumn.
