- Suitable Location: garden bed or container in a sunny spot with good air circulation
- Suitable For:
- Is Weed: No
- Allergenicity: low
Environmental Needs
- Climate: {"temperatureRange":"5–30°C"}
- Hardiness: {"zones":"5–9"}
- Misting: rarely required, only if ambient humidity is very low
- Drainage: Fast-draining; avoid heavy, water-retentive soils.
- Soil Type: Well-draining, sandy loam with some organic matter; tolerates poor soils but benefits from compost.
Maintenance Level
- Maintenance Level: very low
- Toughness Level: high
- Pruning Frequency: As needed throughout the growing season; deadhead regularly to prolong flowering.
- Pruning Intensity: Light; primarily involves removing faded blooms and occasional leggy stems.
Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); 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 good air circulation to prevent heat stress.
Care Requirements
Care Difficulty
very easyeasy
Sunlight
full sun to partial shade
Rotate pots 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 but infrequently to encourage deep roots; avoid overwatering, especially in winter; ensure soil dries slightly between waterings.
Soil
well-draining, sandy or loamy soil with moderate organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil dries between waterings; use raised beds in heavy soils; mulch to retain moisture.
Temperature
Prefers cool to moderate temperatures (60–75°F/15–24°C); thrives in spring and fall; sensitive to extreme heat and frost.
Protect from frost; avoid sudden temperature fluctuations; maintain moderate humidity.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer to moist soil to prevent root burn; stop fertilizing when plant is dormant; use organic options like compost tea for gentle feeding.
Propagation
Methods
Stem cuttings or seed; seeds are the most common method for this annual species.
Step-by-Step Propagation Guide
- Prepare medium.
- Sow seeds or take cuttings.
- Maintain consistent moisture.
- Transplant once established.
Best Time: Spring or early summer for cuttings; sow seeds in fall or early spring for overwintering.
Environment
Warm (65–75°F/18–24°C), humid, and bright indirect light; protect from strong winds or direct sun.
Medium
Well-draining potting mix or seed-starting medium; add perlite for extra drainage if needed.
Hormone
Not necessary for seeds; optional for cuttings to encourage rooting.
Timeline
Seeds germinate in 1–3 weeks; cuttings root in 2–4 weeks; plants establish in 1–2 months.
Tools Needed
Seed trays, pots, pruners, rooting hormone (optional), misting bottle.
Quick Tips
Keep soil consistently moist but not waterlogged; provide gentle bottom heat for faster germination; thin seedlings to prevent overcrowding.
Pruning & Repotting
Pruning Guide
Method
Snip spent flowers just above a leaf node or lateral bud; trim leggy stems to promote bushier growth.
Pruning Plan
Minimal pruning needed; focus on removing spent flowers to encourage reblooming and maintaining shape.
Tools
Hand pruners or sharp scissors; clean tools between cuts to prevent disease spread.
Checklist
Remove dead or faded flowers; trim leggy growth; clean tools; avoid over-pruning healthy stems.
Repotting Guide
Best Season
Early spring, before active growth begins.
Pot Size
One size up from current pot (e.g., +2 inches in diameter).
Method
Gently remove plant; trim any dead roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly after repotting.
Suggestions
Not typically required for annuals; if grown in pots, repot annually in spring to refresh soil and provide more space.
Checklist
Choose appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting; place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply at the base; ensure proper drainage; adjust frequency seasonally.
How to Apply Water Properly
Water at the base of the plant, focusing on the root zone; apply until water begins to drain from the bottom; avoid wetting foliage to prevent fungal issues.
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 perlite or coarse sand for drainage; incorporate compost for fertility; avoid compacting soil.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in heat; leaf drop or browning in cold.
Cold Stress
Low temperatures slow growth and can cause root damage; frost can kill tender parts of the plant.
Solution: Provide frost protection in cold climates; avoid overwatering in cool conditions; move potted plants indoors if temperatures drop below 50°F (10°C).
Hot Stress
Excessive heat can cause wilting, leaf scorch, and reduced flowering; may go dormant in extreme heat.
Solution: Provide afternoon shade; increase watering frequency; use mulch to retain soil moisture; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during growing season; avoid winter feeding; water after fertilizing.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; fertilize every 4–6 weeks during active growth; avoid fertilizing in winter.
