Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but blooms best in full sun.
Sunlight Tolerance Tips:
Acclimate plants gradually if moving from shade to sun; protect from intense midday heat in hot climates; ensure good air circulation to prevent fungal issues.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun
Rotate plants for even growth; use shade cloth in extreme heat; avoid placing in drafty areas.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently; ensure soil dries 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).
Avoid heavy clay soils; amend with organic matter; ensure pots have drainage holes.
Temperature
Hardy in USDA zones 3–9; tolerates wide temperature ranges; prefers 60–80°F (15–27°C) for optimal growth.
Avoid sudden temperature fluctuations; protect from frost; ensure good air circulation in hot weather.
Fertilizing
every 4–6 weeks during spring and summer, none in fall and winter
Fertilize sparingly to avoid leggy growth; apply in early morning or evening; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division; seeds can also be sown directly in spring or fall.
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: Spring or early fall when temperatures are mild and growth is active.
Environment
Warm, humid conditions with indirect light; maintain consistent moisture.
Medium
Well-draining potting mix with perlite or sand; can also root in water.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 2–4 weeks; plants can be transplanted after 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use clean tools to prevent disease; keep cuttings out of direct sun; maintain humidity with a plastic bag if needed.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth; cut stems just above a leaf node or bud.
Pruning Plan
Remove spent flowers to encourage reblooming; trim leggy stems to maintain shape; cut back in late fall or early spring.
Tools
Pruning shears, gloves, clean blades.
Checklist
Sterilize tools; prune dead or damaged growth; cut at an angle; clean up debris after pruning.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter); ensure good drainage.
Method
Remove plant gently; trim roots if necessary; place in a slightly larger pot with fresh soil; water thoroughly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for container-grown plants.
Checklist
Choose appropriate pot size; use fresh soil mix; water after repotting; place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; allow soil to dry between waterings; avoid wetting foliage.
How to Apply Water Properly
Water at the base of the plant, targeting the root zone; apply until water begins to drain from the bottom; water early in the morning to minimize evaporation.
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 dryness.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf scorch, or stunted growth in excessive heat; leaf drop or frost damage in cold stress.
Cold Stress
Plants may become dormant or die back in freezing temperatures; frost can damage tender growth.
Solution: Mulch heavily in winter; protect from frost with row covers; choose hardy varieties for cold climates.
Hot Stress
Leaves may wilt, curl, or develop brown edges; flowering may be reduced in extreme heat.
Solution: Provide afternoon shade; water deeply and mulch to retain moisture; increase humidity if possible.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid winter feeding; flush soil periodically.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; fertilize every 4–6 weeks during growing season; avoid fertilizing in winter.
