Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter harsh light.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly but allow soil to dry between waterings; avoid overwatering.
Soil
well-draining, loamy soil with added organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid compacted soil.
Temperature
Prefers 65–75°F (18–24°C); tolerates mild fluctuations but avoid extremes.
Avoid placing near drafty windows; maintain consistent room temperature.
Fertilizing
every 4–6 weeks during active growth with balanced liquid fertilizer
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings in water or moist soil.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Place in medium.
- Maintain moisture.
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 typically form in 2–4 weeks; new growth in 6–8 weeks.
Tools Needed
Pruners, rooting hormone (optional), small pots or jars, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sanitize tools; prune during active growth; remove dead or diseased parts.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Move to a pot 1–2 inches larger in diameter than the current one.
Method
Use fresh potting mix; ensure good drainage; gently tease out rootbound plants.
Suggestions
Repot every 1–2 years or when roots outgrow the pot; beneficial for growth and health.
Checklist
Check root health; use fresh soil; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring even moisture reaches the root zone without saturating the leaves.
Watering Schedule Tips
Water when the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate organic matter for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or stunted growth in response to sudden temperature changes.
Cold Stress
Slows growth and may cause leaf discoloration or dieback in temperatures below 50°F (10°C).
Solution: Move to a warmer location; protect from drafts; use a space heater if necessary.
Hot Stress
Leaves may wilt, curl, or develop brown edges in excessive heat above 85°F (29°C).
Solution: Provide shade; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute correctly; apply during active growth; avoid dormant periods.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
