- Maintenance Level: very low
- Toughness Level: very high
- Pruning Frequency: As needed, typically after flowering or when deadheading is required.
- Pruning Intensity: Light pruning; remove only spent flowers or damaged leaves.
Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight to avoid scorching; place in a location with consistent light exposure; for indoor growth, use a south-facing window.
Care Requirements
Care Difficulty
very easyeasy
Sunlight
full sun to partial shade
Rotate plants weekly for even growth; use sheer curtains to filter intense midday sun; supplement with grow lights if natural light is insufficient.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overhead watering to prevent fungal issues.
Soil
well-drained, loamy soil with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil is not compacted; avoid overwatering to prevent root rot; enrich soil annually with organic matter.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C); thrives in cooler climates and may struggle in extreme heat.
Avoid sudden temperature fluctuations; protect from late frosts; maintain consistent temperatures for optimal growth.
Fertilizing
every 4–6 weeks during growing season
Apply fertilizer to moist soil to prevent root burn; flush soil occasionally to prevent salt buildup; reduce feeding for mature plants.
Propagation
Methods
Seed propagation is most common; can also be propagated by division in early spring.
Step-by-Step Propagation Guide
- Sow seeds shallowly in a seed tray.
- Keep moist and warm until germination.
- Thin seedlings once they have a few true leaves.
- Transplant to individual pots or garden beds.
Best Time: Spring or early summer when temperatures are mild and growth is active.
Environment
Warm (65–75°F or 18–24°C), humid environment with bright indirect light; keep soil consistently moist but not waterlogged.
Medium
Well-draining seed starting mix or a mix of sand and peat moss.
Hormone
Not necessary for seed propagation; division requires no hormone.
Timeline
Seeds germinate in 1–3 weeks under optimal conditions; division establishes quickly within a few weeks.
Tools Needed
Seed trays, potting mix, watering can, labels, and a heat mat (optional).
Quick Tips
Sow seeds in groups to ensure germination; use a mister to keep soil moist without disturbing seeds; harden off seedlings before transplanting.
Pruning & Repotting
Pruning Guide
Method
Snip off dead or yellowing leaves at the base; deadhead spent flowers to encourage further blooming.
Pruning Plan
Minimal pruning required; focus on removing dead or damaged foliage to maintain plant health and appearance.
Tools
Hand pruners or sharp scissors.
Checklist
Disinfect tools before use; prune in early morning or evening; remove only dead or damaged parts; avoid over-pruning.
Repotting Guide
Best Season
Early spring before the growing season begins.
Pot Size
Choose a pot one size larger than the current one (1–2 inches wider in diameter).
Method
Gently remove the plant from its pot; trim any circling roots; place in a new pot with fresh soil; water thoroughly after repotting.
Suggestions
Repot only when the plant becomes root-bound or outgrows its container; typically every 2–3 years.
Checklist
Select appropriate pot size; prepare fresh soil mix; trim roots if necessary; water after repotting; place in a shaded area for a few days.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply at the base; ensure proper drainage; adjust frequency with seasons.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain freely; water early in the day to minimize evaporation and fungal growth.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add compost or well-rotted manure to improve fertility and structure; incorporate perlite or sand for better drainage.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or browning leaf edges in excessive heat; cold stress may cause leaf discoloration or dieback.
Cold Stress
Low temperatures can slow growth and cause root damage; frost can kill young plants or damage flowering parts.
Solution: Protect with frost cloth or mulch in cold climates; avoid planting in low-lying areas prone to frost accumulation; ensure good air circulation to prevent cold dampness.
Hot Stress
Excessive heat can lead to dehydration, leaf scorch, and reduced vigor; may bolt prematurely in response to heat stress.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture; ensure good air circulation to reduce heat buildup.
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; apply every 4–6 weeks during the growing season (spring and summer); avoid fertilizing in winter.
