Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Tolerates partial shade but may produce fewer blooms.
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 mildew in humid conditions.
Care Requirements
Care Difficulty
easyModerate
Sunlight
full sun
Full sun is best for blooms; rotate pots for even light exposure; provide shade during extreme heat.
Watering
every 7–10 days during active growth, less frequently in dormant periods
Water at the base to avoid foliage wetting; ensure thorough saturation to reach roots; avoid overwatering to prevent root rot.
Soil
fertile, moist, well-drained loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; amend with organic matter; avoid compacted soil.
Temperature
Hardy in USDA zones 3–8. Prefers cool to moderate temperatures (60–75°F or 15–24°C) during active growth.
Protect from frost; water more in heat; ensure good air circulation in humid conditions.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize once in spring; use a balanced formula; avoid over-fertilizing to prevent leggy growth.
Propagation
Methods
Stem cuttings or division in spring or early fall.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist medium.
- Keep humid. For division, dig up clumps.
- Separate into sections.
- Replant immediately.
Best Time: Spring or early fall when the plant is actively growing.
Environment
Warm (65–75°F or 18–24°C), high humidity, and partial shade for cuttings.
Medium
Well-draining potting mix with perlite or sand for cuttings; garden soil for division.
Hormone
Optional, but rooting hormone can improve success rates for cuttings.
Timeline
Cuttings may root in 4–6 weeks; division plants establish in 1–2 growing seasons.
Tools Needed
Pruners, rooting hormone, pots, well-draining soil mix, misting spray bottle.
Quick Tips
Take cuttings in spring; keep cuttings humid; divide every 2–3 years to maintain vigor.
Pruning & Repotting
Pruning Guide
Method
Deadhead by snipping spent blooms; cut back stems to basal growth in fall or spring.
Pruning Plan
Remove spent flowers to encourage reblooming; cut back in late fall or early spring to maintain shape and vigor.
Tools
Pruners, gloves, clean shears.
Checklist
Clean tools; deadhead regularly; cut back in fall/spring; remove dead or diseased stems.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot (e.g., +2–3 inches in diameter).
Method
Gently remove the plant; trim any dead roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound. Division at repotting can rejuvenate older plants.
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 early in the day; avoid wetting foliage; ensure proper drainage.
How to Apply Water Properly
Water directly at the root zone until the soil is moist but not waterlogged. Ensure water penetrates deeply to encourage root growth, 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 active growth, reducing frequency in winter. Adjust based on rainfall and soil moisture; allow the top inch of soil to dry between waterings.
Soil Improvement
Add compost or well-rotted manure to enhance fertility and structure; incorporate perlite or sand for drainage.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or wilting in extreme heat; stunted growth or bud drop in cold stress.
Cold Stress
Plants may become dormant or show leaf discoloration in temperatures below freezing, though roots are typically hardy.
Solution: Mulch heavily around the base in winter; protect from harsh winds; avoid planting in frost pockets.
Hot Stress
Leaves may wilt, scorch, or drop; flowering may be reduced in prolonged heat.
Solution: Provide afternoon shade in extreme heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in spring; avoid high nitrogen; water after application.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring. Avoid high-nitrogen formulas, which can reduce blooms. Apply lightly around the base, avoiding direct contact with roots.
