Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day) in spring and summer; partial shade during peak summer heat.
Sunlight Tolerance Tips:
Gradually acclimate to full sun to prevent scorching; provide shade during extreme heat; adjust placement based on light intensity.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Monitor leaf color for light stress, use shade cloth in intense sun, rotate plant for even exposure.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly until runoff, allow soil to dry between waterings, avoid wetting foliage.
Soil
well-drained, loamy soil with moderate fertility
pH: Slightly acidic to neutral (6.0–7.0).
Use raised beds for better drainage, avoid heavy clay soils, amend with organic matter.
Temperature
Prefers 65–85°F (18–29°C); tolerates cooler temperatures but thrives in warmth.
Avoid drafts, maintain consistent temperatures, protect from frost and extreme heat.
Fertilizing
every 4–6 weeks during spring and summer
Dilute fertilizer to half strength, avoid over-fertilizing, apply to moist soil to prevent root burn.
Propagation
Methods
Softwood stem cuttings with at least two nodes.
Step-by-Step Propagation Guide
- Take cutting, apply hormone, plant in medium, maintain humidity, wait for roots.
Best Time: Late spring to early summer when new growth is vigorous.
Environment
High humidity (70–80%), indirect light, and warm temperatures (70–75°F).
Medium
Well-draining mix of peat and perlite or cactus mix.
Hormone
Recommended to use rooting hormone for faster root development.
Timeline
Roots in 3–6 weeks; establish in new pot after 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic bags or propagator.
Quick Tips
Use healthy parent stems, keep medium moist, provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Thinning cuts to remove old wood, heading cuts to encourage branching.
Pruning Plan
Shape plant, remove dead/diseased growth, encourage fruiting and airflow.
Tools
Pruning shears, loppers, gloves, disinfectant.
Checklist
Disinfect tools, remove dead/diseased wood, shape plant, clean up debris.
Repotting Guide
Best Season
Early spring before active growth begins.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Remove plant gently, trim roots if needed, use fresh soil mix, ensure good drainage.
Suggestions
Repot every 2–3 years or when roots fill the pot; essential for vigorous growth.
Checklist
Prepare new pot, trim roots, add fresh soil, water lightly, place in shade for recovery.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid wetting leaves, adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water early in the day to minimize evaporation.
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 good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, stunted growth, or chlorosis in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf drop or dieback in prolonged cold; susceptible to frost damage.
Solution: Protect with frost cloth in winter, avoid sudden temperature drops, ensure good air circulation.
Hot Stress
Leaves may scorch, wilt, or drop; reduced flowering and fruiting in excessive heat.
Solution: Provide shade during peak heat, increase watering, use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute correctly, apply during active growth, avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer every 4–6 weeks during growing season (spring/summer); reduce or stop in fall/winter.
