Care Requirements
Care Difficulty
moderateeasy
Sunlight
partial shade to full sun
Morning sun is ideal; avoid intense afternoon sun; adjust shade as seasons change.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but allow soil to dry slightly between waterings; avoid waterlogging, especially in winter.
Soil
moist, fertile, well-drained loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; enrich with organic matter; maintain consistent moisture.
Temperature
Cool to moderate temperatures (60–75°F or 15–24°C); tolerates cold but prefers protection from extreme frost.
Protect from frost; avoid heat stress with shade; maintain moderate temps.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize during active growth; dilute to prevent burn; stop in dormant periods.
Propagation
Methods
Division or stem cuttings; division is preferred for mature plants.
Step-by-Step Propagation Guide
- Divide clumps.
- Cut stems just below a node.
- Remove lower leaves.
- Plant in medium.
- Keep moist.
Best Time: Early spring or fall when the plant is not in full bloom.
Environment
Warm, humid, and bright indirect light; protect from direct sun.
Medium
Well-draining potting mix with perlite or sand; can also be propagated in water.
Hormone
Optional but can help with stem cuttings.
Timeline
Division: immediate establishment; stem cuttings: roots in 2–4 weeks, mature plant in 1–2 months.
Tools Needed
Sharp knife, pruning shears, rooting hormone (optional), pots, well-draining mix.
Quick Tips
Divide every 3–4 years to maintain vigor; use clean tools to prevent disease.
Pruning & Repotting
Pruning Guide
Method
Deadhead spent flowers; trim back yellowing or damaged leaves.
Pruning Plan
Remove spent flowers to encourage reblooming; cut back foliage after flowering to tidy the plant.
Tools
Pruning shears, gloves, clean blades.
Checklist
Remove dead flowers; trim damaged leaves; clean tools after use.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot with drainage holes; ensure it’s not excessively large.
Method
Gently remove plant; trim roots if necessary; replant in fresh, well-draining soil with added organic matter.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound; division is often done during repotting.
Checklist
Check root health; use fresh soil; ensure drainage; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wet foliage
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; avoid wetting foliage to prevent fungal issues; ensure excess water drains away.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry, typically every 7–10 days during active growth; reduce frequency in winter to monthly or as needed.
Soil Improvement
Add compost or well-rotted manure; incorporate perlite or sand for drainage.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or bud drop in extreme heat or cold.
Cold Stress
Stem damage, leaf discoloration, or dieback in prolonged freezing temperatures.
Solution: Mulch heavily in winter; protect from frost with row covers or move to a sheltered location.
Hot Stress
Leaf scorch, wilting, or reduced flowering in excessive heat.
Solution: Provide shade during peak heat; increase watering; improve air circulation.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; dilute properly; fertilize during growing season; cease in winter.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during spring and summer; avoid fertilizing in fall and winter.
