Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily). Tolerates partial shade but may produce fewer flowers.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight if moved from shade. Avoid placing in hot, reflective surfaces that can scorch leaves. Outdoor placement is ideal for full sun exposure.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun
Rotate plants for even light exposure; use shade cloth in extreme heat; ensure unobstructed sunlight.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently to encourage deep roots; avoid waterlogging; ensure soil dries slightly between waterings.
Soil
well-drained, sandy loam with moderate fertility
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil is loose and crumbly; avoid compacted soil; amend with organic matter annually.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C). Tolerates frost but may struggle in prolonged heat above 85°F (29°C).
Monitor temperature extremes; use mulch for insulation; adjust watering with temperature changes.
Fertilizing
every 4–6 weeks during growing season
Apply fertilizer after watering to prevent root burn; stop fertilizing when flowering begins to avoid excessive foliage.
Propagation
Methods
Seed propagation is the most common and reliable method.
Step-by-Step Propagation Guide
- Sow seeds directly in the garden or containers.
- Thin seedlings to 6–12 inches apart.
- Water gently until established.
Best Time: Spring, after the last frost, for optimal germination and establishment.
Environment
Warm (65–70°F or 18–21°C), bright, indirect light with consistent moisture.
Medium
Well-draining seed starting mix or sandy loam.
Hormone
Not required for seeds.
Timeline
Germination in 1–3 weeks; plants reach maturity in 60–90 days.
Tools Needed
Seed trays, labels, watering can, and garden trowel.
Quick Tips
Sow seeds in groups for better germination rates; keep soil consistently moist but not waterlogged.
Pruning & Repotting
Pruning Guide
Method
Deadhead spent flowers by cutting just above a leaf or bud. Trim back leggy stems to promote bushier growth.
Pruning Plan
Minimal pruning required. Focus on removing spent flowers to encourage reblooming and tidying the plant.
Tools
Hand pruners or sharp scissors.
Checklist
Use clean tools; deadhead regularly; trim only as needed; dispose of pruned material.
Repotting Guide
Best Season
Early spring, before active growth begins.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Gently remove the plant, trim any dead or crowded roots, and repot in fresh, well-draining soil with a slightly larger container.
Suggestions
Not typically required for garden-grown plants. Container-grown plants may need repotting every 2–3 years if root-bound.
Checklist
Choose the right pot size; use fresh soil; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency seasonally.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone. Apply until water begins to drain from the bottom, then allow the soil to dry before the next watering.
Watering Schedule Tips
Water deeply once per week during active growth, reducing frequency in winter to once every 3–4 weeks. Adjust based on rainfall and soil moisture retention.
Soil Improvement
Add compost or well-rotted manure to enhance fertility and drainage. Incorporate sand or perlite if soil is heavy.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or wilting in excessive heat; stunted growth or failure to flower in cold stress.
Cold Stress
Low temperatures slow growth and may cause leaf discoloration, but the plant is generally hardy to frost.
Solution: Provide frost protection in extreme cold (e.g., row covers). Mulch around the base to insulate roots.
Hot Stress
Excessive heat can lead to wilting, flower abortion, and reduced vigor.
Solution: Provide afternoon shade, increase watering frequency, and ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during growing season; avoid winter feeding; follow package instructions.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during active growth (spring and summer). Avoid fertilizing in winter.
