Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy with insufficient light.
Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight to prevent scorching; for indoor placement, use a south-facing window with direct light.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant weekly for even growth; use sheer curtains to filter harsh midday sun in summer.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until runoff, ensure soil dries out between waterings, and avoid overhead watering to prevent fungal issues.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; test pH annually.
Temperature
Prefers 60–75°F (15–24°C); tolerates mild frosts but thrives in warm, dry conditions.
Avoid sudden temperature fluctuations; protect from drafts; maintain consistent warmth during active growth.
Fertilizing
every 4–6 weeks during spring and summer
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings taken from semi-hardwood growth.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Maintain humidity.
Best Time: Late spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F), high humidity (70–80%), and bright indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus potting soil.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots typically form in 4–8 weeks; establish in new pot after 3–4 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, disease-free cuttings; maintain consistent moisture; avoid direct sunlight.
Pruning & Repotting
Pruning Guide
Method
Selective thinning of branches and light shaping to maintain form.
Pruning Plan
Shape the plant, encourage bushier growth, and remove dead or weak stems to improve air circulation.
Tools
Sharp bypass pruners, sterilizing solution, gloves.
Checklist
Sterilize tools; prune dead/damaged stems; shape evenly; clean up debris.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage.
Method
Remove plant gently, trim roots if needed, place in new pot with fresh soil, and water lightly.
Suggestions
Repot every 2–3 years or when roots outgrow the container to refresh soil and provide space.
Checklist
Choose appropriate pot; prepare fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture with a finger; water deeply; ensure drainage; adjust frequency seasonally.
How to Apply Water Properly
Water directly at the root zone, ensuring even moisture penetration to a depth of 6–8 inches, and allow excess water to drain freely from the pot or soil surface.
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 completely between waterings.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, wilting, or browning leaf edges in excessive heat; stunted growth or yellowing in cold stress.
Cold Stress
Low temperatures slow growth and may cause root damage or dieback in prolonged cold.
Solution: Protect from frost with mulch or move to a sheltered location; avoid overwatering in cold conditions.
Hot Stress
Excessive heat can lead to leaf scorch, dehydration, and reduced flowering.
Solution: Provide afternoon shade, increase humidity, and water deeply during heatwaves.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during growing season; avoid winter feeding.
Fertilizing Method
Use a balanced, slow-release fertilizer diluted to half strength every 4–6 weeks during spring and summer; avoid fertilizing in fall and winter.
