Care Details
Ideal Sunlight Coverage:
Full sun to partial shade (4–6 hours of direct sunlight daily); adjust for intense summer sun to prevent scorching.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; provide shade during peak afternoon hours; for indoor plants, place near south-facing windows with sheer curtains.
Care Requirements
Care Difficulty
easymoderate
Sunlight
partial shade to full sun
Rotate plant for even light exposure; use reflective surfaces to enhance light; monitor for signs of sunburn.
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-draining, fertile, slightly alkaline soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use raised beds for better drainage; avoid compacted soil; test pH annually.
Temperature
Cool to moderate temperatures (60–70°F or 15–21°C); prefers cooler nights; tolerates mild frosts but not prolonged cold.
Avoid sudden temperature fluctuations; maintain good air circulation; protect from drafts.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer to moist soil to prevent root burn; flush soil occasionally to prevent salt buildup; stop fertilizing when blooms fade.
Propagation
Methods
Stem cuttings or seed; stem cuttings are more reliable for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist and warm.
Best Time: Early spring or late summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain consistent moisture.
Medium
Well-draining potting mix with perlite or sand; can also root in water initially.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity with a plastic cover; avoid direct sunlight.
Pruning & Repotting
Pruning Guide
Method
Deadhead spent flowers; trim stems just above a leaf node or bud; cut back overgrown stems to encourage bushiness.
Pruning Plan
Remove spent flowers to encourage reblooming; trim leggy growth to maintain shape; cut back after flowering to rejuvenate.
Tools
Pruning shears, sterilized scissors.
Checklist
Sterilize tools; prune dead or diseased parts; shape as needed; clean up debris.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter); ensure good drainage.
Method
Remove plant gently; trim roots if crowded; place in a slightly larger pot with fresh soil; water thoroughly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for younger plants to support growth.
Checklist
Choose appropriate pot; prepare fresh soil mix; handle roots carefully; water 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; allow excess water to drain freely; water in the morning to reduce evaporation and fungal risk.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or bud drop in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf discoloration, and can lead to root damage in freezing conditions.
Solution: Protect from frost with mulch or cloches; move potted plants indoors during freezes; avoid overwatering in cold weather.
Hot Stress
Leaves may wilt, scorch, or drop; flowers may fade quickly; growth may slow.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to base; avoid foliage contact.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; fertilize every 4–6 weeks during active growth (spring and summer); avoid fertilizing in winter.
