Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to lower light in winter to prevent leaf burn.
Sunlight Tolerance Tips:
Gradually acclimate to brighter light to avoid scorching; place in a spot with filtered light if outdoors, or near an east-facing window indoors.
Care Requirements
Care Difficulty
easyeasy
Sunlight
bright, indirect light
Rotate plant weekly for even growth; use sheer curtains to filter direct sun; avoid south-facing windows in summer.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly until it drains, allow soil to dry between waterings, avoid letting the plant sit in water.
Soil
well-draining, peat-based potting mix
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pot has drainage holes; avoid heavy clay soils; top-dress with compost annually.
Temperature
Prefers 65–80°F (18–27°C); tolerates slight fluctuations but avoid drafts or extreme heat.
Keep away from air vents; use a humidifier in dry environments; monitor room temperature changes.
Fertilizing
every 4–6 weeks during active growth (spring and summer)
Flush soil occasionally to prevent salt buildup; reduce feeding in winter; apply fertilizer after watering.
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, keep moist, wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid, and bright indirect light with consistent moisture.
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), container, water or soil medium.
Quick Tips
Use a clear container to monitor root growth; keep cuttings out of direct sun; change water every few days if using water propagation.
Pruning & Repotting
Pruning Guide
Method
Pinch back stems or use clean shears to cut just above a leaf node.
Pruning Plan
Remove leggy growth and spent flowers to encourage bushier growth and more blooms.
Tools
Clean scissors or pruning shears, gloves.
Checklist
Sanitize tools, prune dead/damaged growth, shape plant, clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season 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; promotes fresh soil and growth.
Checklist
Check root bound status, prepare new pot, trim roots, add fresh soil, water lightly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, adjust for season.
How to Apply Water Properly
Water directly at the root zone, ensure even moisture distribution, allow excess water to drain, water in the morning to reduce evaporation.
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.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, wilting, or stunted growth if too cold; leaf drop or brown leaf tips if too hot.
Cold Stress
Slows growth, may cause root rot due to reduced water uptake in cold soil.
Solution: Move to a warmer spot, avoid cold drafts, ensure soil doesn't stay wet.
Hot Stress
Leaves may scorch, growth may slow, or plant may drop leaves to conserve water.
Solution: Increase humidity, provide shade, water more frequently but avoid overwatering.
Fertilizing Guide
Fertilizing Checklist
Check season, dilute fertilizer, apply to moist soil, rinse container after use.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in fall/winter.
