Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); tolerates partial shade but may produce fewer seeds.
Sunlight Tolerance Tips:
Acclimate plants gradually to full sun if moved from shade; protect from intense midday sun in hot climates; ensure adequate air circulation to prevent fungal issues.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Full sun is best; avoid deep shade; rotate plants for even growth.
Watering
every 7–10 days during active growth, less frequently in dormant periods
Water thoroughly but infrequently to encourage deep roots; avoid waterlogging; water early in the day to minimize evaporation.
Soil
well-drained, fertile loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; amend with organic matter; maintain consistent moisture.
Temperature
Cool to moderate temperatures (60–75°F/15–24°C); prefers cooler climates; may go dormant in extreme heat.
Protect from frost; provide shade in summer; maintain consistent moisture.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize in spring before growth begins; use a balanced formula; avoid high-nitrogen fertilizers.
Propagation
Methods
Seeds or division; seeds are the most common method for large-scale propagation.
Step-by-Step Propagation Guide
- Prepare soil.
- Sow seeds or divide clumps.
- Keep moist.
- Thin or space as needed.
Best Time: Spring or early fall when temperatures are moderate and moisture is available.
Environment
Warm, moist conditions for seeds; partial shade for young plants; well-drained soil.
Medium
Well-draining soil mix with some organic matter; can be direct-sown in the garden.
Hormone
Not required for seeds; division requires no hormone.
Timeline
Seeds germinate in 1–3 weeks under ideal conditions; division establishes quickly in the growing season.
Tools Needed
Garden trowel, seed spreader, watering can.
Quick Tips
Sow seeds shallowly; keep soil consistently moist; divide every 2–3 years to maintain vigor.
Pruning & Repotting
Pruning Guide
Method
Use a lawnmower or hand shears for even cutting; avoid cutting below 1 inch to prevent damage.
Pruning Plan
Mow regularly to encourage dense growth and prevent flowering if not needed for seed production.
Tools
Lawnmower, hand shears, trimmer.
Checklist
Mow regularly; maintain consistent height; remove debris after cutting.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
Increase pot size by 2–3 inches in diameter if repotting.
Method
Use a well-draining soil mix; gently tease out roots if compacted; ensure good drainage.
Suggestions
Not typically repotted; if grown in containers, repot every 2–3 years to refresh soil.
Checklist
Use fresh soil; ensure drainage; handle roots gently; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure good drainage; avoid overhead watering.
How to Apply Water Properly
Apply water directly to the soil at the base of the plant, ensuring even moisture to a depth of 6–8 inches; allow excess water to drain away; water in the morning to reduce fungal risk.
Watering Schedule Tips
Water deeply once a week during active growth, reducing frequency in winter; adjust based on rainfall and soil moisture.
Soil Improvement
Add compost or well-rotted manure to enhance fertility and structure; ensure good drainage with sand or perlite if needed.
Temperature Stress Management
Signs of Temperature Issues
Yellowing or browning leaves in excessive heat; stunted growth or poor germination in cold conditions.
Cold Stress
Slows growth; may become dormant; prolonged cold can damage roots or prevent regrowth.
Solution: Provide winter mulch for insulation; avoid planting in areas prone to frost; ensure good drainage to prevent root rot.
Hot Stress
Causes wilting, leaf scorch, and reduced vigor; may enter dormancy to conserve energy.
Solution: Provide afternoon shade; increase watering frequency; apply mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; apply in early spring; avoid over-application; water after fertilizing.
Fertilizing Method
Use a balanced, slow-release fertilizer in early spring; avoid over-fertilizing, which can reduce seed quality.
