Environmental Needs
- Climate: {"temperatureRange":"5–30°C"}

- Drainage: Fast-draining to prevent waterlogging; ensure excess water can escape freely from the pot or garden bed.
- Soil Type: Well-draining, loamy soil with added organic matter; can tolerate poor soils but thrives with good fertility.
Maintenance Level
- Maintenance Level: moderate
- Toughness Level: moderate
- Pruning Frequency: Annually, after flowering or in late winter/early spring; light pruning can be done as needed throughout the growing season.
- Pruning Intensity: Moderate; remove up to one-third of the oldest stems to rejuvenate growth; thin out crowded branches
Care Details
Ideal Sunlight Coverage:
Full sun to partial shade; 6–8 hours of direct sunlight per day, with some afternoon shade in hot climates to prevent scorching.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; provide shade during peak summer heat; for indoor plants, place near a south-facing window with filtered light.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate the plant weekly for even light exposure; use sheer curtains to filter intense sunlight; monitor for signs of sunburn or etiolation.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom, avoid frequent shallow watering, and adjust frequency based on season and weather conditions.
Soil
well-draining, loamy soil with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0); adaptable to a range of soil pH levels.
Ensure good drainage to prevent root rot; amend heavy clay soils with organic matter; test soil pH periodically.
Temperature
Prefers warm temperatures between 60–85°F (15–29°C); can tolerate mild frosts but thrives in mild to warm climates.
Monitor temperature changes; adjust watering and light exposure accordingly; protect from sudden temperature drops.
Fertilizing
every 4–6 weeks during spring and summer
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; reduce frequency in dormant periods.
Propagation
Methods
Stem cuttings are the most reliable method; softwood cuttings taken in spring or early summer root most readily.
Step-by-Step Propagation Guide
- Select a healthy stem.
- Cut a 4–6 inch section just below a node.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Maintain humidity and warmth.
Best Time: Spring or early summer when the plant is actively growing; avoid propagation during dormancy or extreme weather conditions.
Environment
High humidity (70–90%), warm temperatures (70–75°F or 21–24°C), and bright indirect light; protect from direct sunlight.
Medium
Well-draining mix of peat, perlite, and sand; can also root in water initially before transferring to soil.
Hormone
Rooting hormone is recommended to improve success rates, especially for hardwood cuttings.
Timeline
Roots typically develop in 4–8 weeks; new growth may appear in 2–3 months; full establishment takes 6–12 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium, plastic bags or propagation dome, misting bottle.
Quick Tips
Use sharp, sterilized tools to prevent infection; maintain consistent moisture in the medium; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Use clean, sharp tools; make cuts just above a leaf node or branch junction; remove dead, damaged, or crossing branches first.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or overgrown branches; best done after flowering or in late winter/early spring.
Tools
Pruning shears, loppers (for thicker stems), sterilizing solution, gloves.
Checklist
Sterilize tools; prune at the right time; make clean cuts; remove dead/diseased wood; shape the plant evenly.
Repotting Guide
Best Season
Late winter or early spring, before the active growing season begins; avoid repotting during flowering or dormancy.
Pot Size
Choose a pot one size larger (1–2 inches wider in diameter) than the current one; ensure it has drainage holes.
Method
Gently remove the plant from its pot; trim any circling roots; place in a new pot with fresh, well-draining soil; water thoroughly after repotting.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound; beneficial for rejuvenating soil and encouraging new growth.
Checklist
Select appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting; place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency seasonally.
How to Apply Water Properly
Water directly at the root zone, ensuring even moisture distribution; water early in the morning or late in the evening to minimize evaporation; allow excess water to drain completely to prevent root rot.
Watering Schedule Tips
Water deeply once every 7–10 days during active growth in spring and summer; reduce frequency to every 2–3 weeks in fall and winter, allowing soil to dry out between waterings.
Soil Improvement
Add compost or well-rotted manure to enhance fertility; incorporate perlite or sand to improve drainage; use mulch to retain moisture and suppress weeds.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis or leaf drop in extreme heat; wilting or browning leaf edges in cold stress; stunted growth in temperature fluctuations.
Cold Stress
Low temperatures slow growth and can cause leaf drop; prolonged exposure to freezing temperatures may lead to dieback or death.
Solution: Protect from frost with a frost cloth or move to a sheltered location; avoid overwatering in cold conditions to prevent root rot.
Hot Stress
Excessive heat can cause leaf scorch, wilting, and reduced flowering; dehydration may lead to leaf drop.
Solution: Provide afternoon shade; increase watering frequency; use mulch to retain soil moisture; mist foliage during extreme heat.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during active growth; avoid over-fertilization; flush soil periodically.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season (spring and summer); avoid fertilizing in fall and winter.
