Care Details
Ideal Sunlight Coverage:
Full sun to partial shade (4–6 hours of direct sunlight daily); prefers morning sun and afternoon shade in hot climates.
Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight; protect from harsh afternoon sun to prevent scorching; adjust placement based on seasonal light changes.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter intense light; avoid direct sun during peak heat.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but allow soil to dry slightly between waterings; avoid overhead watering to prevent fungal issues; ensure good drainage.
Soil
well-draining, fertile, loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Avoid heavy clay soils; use raised beds for better drainage; test soil pH annually.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C); thrives in cooler summers and can tolerate light frosts.
Protect from frost; avoid extreme heat; maintain consistent temperatures for optimal growth.
Fertilizing
every 4–6 weeks during growing season
Apply fertilizer after watering to prevent root burn; stop fertilizing in late summer to prepare for dormancy; use a phosphorus-rich formula to encourage blooms.
Propagation
Methods
Stem cuttings or division; stem cuttings are the most common method for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- 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 typically form in 2–4 weeks; new growth may appear in 4–6 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
Pinch back tips for bushier growth; deadhead spent flowers; cut back leggy stems to a healthy bud.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers to prolong blooming.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; prune in early morning; remove dead or diseased growth; shape the plant.
Repotting Guide
Best Season
Early spring before new growth begins; avoid repotting during flowering or dormancy.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure good drainage holes.
Method
Remove plant gently; trim any circling roots; place in a slightly larger pot with fresh, well-draining soil; water thoroughly after repotting.
Suggestions
Repot every 1–2 years or when roots fill the pot; beneficial for container-grown plants to refresh soil and provide space.
Checklist
Choose appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture daily; water deeply; ensure drainage; adjust for weather.
How to Apply Water Properly
Water at the base of the plant, targeting the root zone; apply until water drains from the bottom; water early in the morning to minimize evaporation and fungal growth.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; increase frequency during hot, dry periods; reduce 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, leaf drop, or stunted growth in excessive heat; yellowing or browning leaves in cold stress.
Cold Stress
Slows growth and can cause leaf damage or dieback in temperatures below 50°F (10°C); may enter dormancy in colder climates.
Solution: Provide frost protection with mulch or row covers; move potted plants indoors; avoid overwatering in cold conditions.
Hot Stress
Leaves may wilt, scorch, or drop; flowering may be reduced in prolonged heat.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute properly; apply during growing season; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during growing season; avoid fertilizing in winter.
