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 to intense sunlight; protect from harsh afternoon sun in hot climates; ensure adequate spacing for air circulation.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plants for even light exposure; use shade cloth in extreme heat; avoid placing in drafty areas.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until runoff, allow soil to dry slightly between waterings, avoid overhead watering to prevent fungal issues.
Soil
well-draining, loamy soil with moderate organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; enrich with organic matter; avoid compacted soil.
Temperature
Prefers 65–85°F (18–29°C); tolerates heat but may struggle below 50°F (10°C); thrives in moderate temperatures.
Protect from frost; water deeply in heat; adjust care seasonally.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize lightly; avoid high-nitrogen formulas; stop feeding before winter.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common 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: Early spring or late summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain consistent moisture.
Medium
Well-draining potting mix with perlite or sand; can also root in water.
Hormone
Rooting hormone is recommended for faster and more reliable rooting.
Timeline
Roots typically form in 3–6 weeks; new growth may appear in 2–3 months.
Tools Needed
Pruners, rooting hormone, small pots, well-draining medium, plastic wrap or propagator.
Quick Tips
Use sharp, clean tools; keep cuttings out of direct sun; maintain humidity for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Deadhead spent flowers; shear lightly after first bloom; cut back hard in late fall or early spring.
Pruning Plan
Remove spent flowers to encourage reblooming; cut back in late fall or early spring to maintain shape and vigor.
Tools
Pruning shears, gloves, clean blades.
Checklist
Clean tools; deadhead regularly; cut back in fall/spring; avoid pruning during peak bloom.
Repotting Guide
Best Season
Early spring before new growth begins; avoid repotting during flowering or extreme temperatures.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage holes.
Method
Remove plant gently; 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 roots fill the container; beneficial for maintaining vigor and bloom quality.
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; ensure drainage; avoid wetting foliage.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; water early in the day to minimize evaporation and leaf wetness; ensure excess water drains away to prevent root rot.
Watering Schedule Tips
Water deeply once a week during active growth; reduce frequency in winter to every 2–3 weeks; adjust based on rainfall and soil moisture.
Soil Improvement
Add compost or well-rotted manure; incorporate perlite or sand for drainage; mulch to retain moisture and improve soil structure.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or bud drop in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf discoloration or dieback; vulnerable to frost damage in winter.
Solution: Mulch heavily in fall; move potted plants indoors before frost; provide frost cloth protection in cold snaps.
Hot Stress
Leaves may scorch, wilt, or drop; flowering may decline in prolonged heat.
Solution: Water deeply during heatwaves; provide afternoon shade; increase humidity around the plant.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in spring; water after fertilizing; avoid contact with roots.
Fertilizing Method
Use balanced, slow-release fertilizer in early spring; avoid over-fertilizing; reduce feeding in late summer/autumn.
