Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day) with tolerance for partial shade, especially in hot climates.
Sunlight Tolerance Tips:
Acclimate seedlings gradually to full sun; protect from intense midday sun in hot regions; ensure good air circulation to prevent scorching.
Care Requirements
Care Difficulty
very easyeasy
Sunlight
full sun to partial shade
Rotate plants for even light exposure; use shade cloth in extreme heat; avoid direct sun on young plants.
Watering
every 7–10 days during active growth, less frequently in dormancy
Water deeply but infrequently; avoid waterlogged soil; adjust based on season and rainfall.
Soil
well-draining, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use raised beds in heavy soils; avoid over-amending with organic matter; test pH if issues arise.
Temperature
Prefers moderate temperatures (65–85°F / 18–29°C); tolerates mild frosts but thrives in warm conditions.
Protect from frost; provide shade in extreme heat; maintain consistent temperatures for optimal growth.
Fertilizing
rarely required, if used then every 3–4 months with balanced, diluted fertilizer
Apply fertilizer after watering to prevent root burn; use organic options for gentle feeding; stop fertilizing before flowering.
Propagation
Methods
Seed propagation is most common; can also be propagated by root division in early spring.
Step-by-Step Propagation Guide
- Sow seeds shallowly.
- Keep moist.
- Thin seedlings.
- Divide roots when clumps become crowded.
Best Time: Spring or early summer when temperatures are mild and growth is active.
Environment
Warm (70–75°F / 21–24°C), humid environment with indirect light for seeds; similar conditions for root division.
Medium
Well-draining seed starting mix or sandy loam for seeds; moist soil for root division.
Hormone
Not typically required for seeds; rooting hormone may aid root division if needed.
Timeline
Seeds germinate in 1–3 weeks; root division establishes in 2–4 weeks.
Tools Needed
Seed trays, pots, trowel, pruners, rooting hormone (optional).
Quick Tips
Sow seeds in groups; thin to strongest seedlings; divide roots in early growth phase.
Pruning & Repotting
Pruning Guide
Method
Snip off dead or yellowing leaves; deadhead flowers to promote continuous blooming.
Pruning Plan
Minimal pruning needed; remove dead or damaged foliage to maintain plant health and appearance.
Tools
Hand pruners, scissors, or fingers for small stems.
Checklist
Sanitize tools; prune dead/damaged parts; deadhead spent flowers; avoid over-pruning.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
One size up from current pot; ensure good drainage holes.
Method
Gently remove plant; trim any dead roots; repot in fresh, well-draining soil with a slightly larger container.
Suggestions
Not typically required unless grown in containers; repot if roots become crowded or growth slows.
Checklist
Choose appropriate pot; prepare fresh soil; handle roots gently; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure drainage; adjust for weather.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone without wetting foliage. Allow excess water to drain away to prevent standing water.
Watering Schedule Tips
Water lightly and infrequently, allowing soil to dry between waterings. Reduce watering in winter to prevent root rot.
Soil Improvement
Add sand or perlite for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or premature flowering in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf discoloration, and can lead to frost damage in prolonged cold.
Solution: Provide frost protection in cold climates; avoid overwatering in cool conditions to prevent root rot.
Hot Stress
Leaves may wilt, curl, or scorch; growth may slow or stop in excessive heat.
Solution: Provide afternoon shade; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid winter feeding; monitor for signs of over-fertilization.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season; avoid fertilizing in winter.
