- Suitable Location: outdoor garden bed in a sunny, sheltered spot
- Suitable For:
- Is Weed: No
- Allergenicity: low
Environmental Needs
- Climate: {"temperatureRange":"10–35°C"}
- Hardiness: {"zones":"8–10"}
- Misting: rarely required, only if ambient humidity is very low
- Drainage: Fast-draining to prevent waterlogging.
- Soil Type: Well-draining, loamy soil with added organic matter; can tolerate poor soils but performs best with some fertility.
Maintenance Level
- Maintenance Level: moderate
- Toughness Level: moderate
- Pruning Frequency: Annually after flowering or in late winter/early spring before new growth begins.
- Pruning Intensity: Moderate; remove up to one-third of the oldest stems to rejuvenate the plant.
Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may produce fewer blooms.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight if moving from shade; protect from harsh afternoon sun in hot climates; ensure good air circulation to prevent sunburn.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant weekly for even growth; use sheer curtains to filter intense light indoors; avoid placing in drafty areas.
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, sandy loam with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Avoid heavy clay soils; use raised beds or containers for better drainage; mulch to retain moisture and suppress weeds.
Temperature
Prefers warm temperatures (65–85°F or 18–29°C); can tolerate mild frosts but thrives in mild to warm climates.
Avoid sudden temperature fluctuations; protect from cold drafts; ensure good air circulation in hot weather.
Fertilizing
every 4–6 weeks during spring and summer
Apply fertilizer after watering to prevent root burn; stop fertilizing when plant is dormant; use a balanced formula for optimal growth.
Propagation
Methods
Stem cuttings or seed; stem cuttings are faster and more reliable for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings below a leaf node.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in moist medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F or 21–24°C), humid environment with indirect light; protect from direct sun.
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 appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium, plastic wrap or propagator.
Quick Tips
Use healthy, non-flowering stems for cuttings; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Cut stems back to a healthy bud or lateral branch; remove crossing or crowded branches to improve air circulation.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased wood; focus on post-flowering pruning to avoid reducing blooms.
Tools
Pruning shears, loppers (for thicker stems), clean, sharp blades.
Checklist
Disinfect tools before use; prune during dry weather; make clean cuts; remove debris after pruning.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure the new pot has 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 2–3 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 and place in appropriate light after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply at the base; ensure proper drainage; adjust frequency based on season and weather.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; water early in the day to minimize evaporation and fungal growth; allow excess water to drain away completely.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure soil is loose and aerated.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in cold; leaf scorch or bud drop in excessive heat.
Cold Stress
Slows growth, may cause leaf drop, and can lead to root damage if temperatures drop below freezing.
Solution: Provide frost protection in cold climates; move potted plants indoors during freezes; use mulch to insulate roots.
Hot Stress
Can cause leaf scorch, wilting, and reduced flowering if exposed to prolonged high temperatures without adequate water.
Solution: Provide afternoon shade in hot climates; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer label for NPK ratio; dilute correctly; apply to moist soil; avoid contact with foliage.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season (spring to early fall); avoid fertilizing in winter.
