Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate partial shade, especially in hot climates.
Sunlight Tolerance Tips:
Acclimate gradually to intense light; protect from direct midday sun to prevent scorching; adjust indoor placement to mimic natural light patterns.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid placing near heat sources.
Watering
every 5–7 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom; allow soil to dry between waterings; avoid wetting foliage.
Soil
well-draining, fertile garden loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix designed for herbs or succulents; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Prefers 60–75°F (15–24°C); cooler temperatures (50–60°F) during dormancy; avoid extreme fluctuations.
Use a thermometer to monitor; group plants for microclimate benefits; adjust care based on seasonal changes.
Fertilizing
every 2 weeks during active growth, monthly in spring and fall
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup; avoid over-fertilizing.
Propagation
Methods
Stem cuttings in water or soil.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Place in medium.
- Maintain moisture and warmth.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light.
Medium
Well-draining soil mix or water with occasional nutrient additions.
Hormone
Optional but can speed up rooting.
Timeline
Roots develop in 2–4 weeks; new growth appears in 4–6 weeks.
Tools Needed
Pruning shears, rooting hormone (optional), small pots or jars, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; change water regularly if using water propagation.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Remove dead or leggy stems to encourage bushier growth; shape as needed for aesthetic or health.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sanitize tools; prune dead or damaged growth; shape plant evenly; dispose of clippings properly.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
Choose a pot 1–2 inches larger in diameter than the current one.
Method
Remove plant gently; trim roots if needed; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 1–2 years or when roots outgrow the pot; beneficial for growth and health.
Checklist
Prepare new pot with drainage; gently remove plant; inspect roots; add fresh soil; water lightly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; avoid wetting leaves.
How to Apply Water Properly
Water directly at the root zone, ensuring even moisture distribution; water deeply to encourage root growth; ensure excess water drains away to prevent waterlogging.
Watering Schedule Tips
Water when 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 organic matter like compost for fertility; ensure proper aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or stunted growth in cold; scorching or leaf curl in excessive heat.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage in prolonged cold.
Solution: Move to a warmer location; insulate pots; avoid cold drafts; reduce watering in cooler conditions.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to heat stress.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute correctly; apply during active growth; stop in dormant season.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
