Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate some direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate plants gradually to direct sunlight; protect from intense midday sun; adjust placement based on seasonal light changes.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter intense light; place near east-facing window for optimal light.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure proper drainage; avoid wetting foliage.
Soil
well-draining, loamy soil with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix of potting soil and perlite; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Prefers 60–75°F (15–24°C); cooler temperatures (50–60°F or 10–15°C) are tolerated during dormancy.
Avoid drafts, maintain consistent temperatures, protect from extreme heat or cold.
Fertilizing
every 4–6 weeks during spring and summer
Dilute fertilizer to prevent burn; fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division of clumps.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, remove lower leaves, dip in rooting hormone, plant in medium, keep moist and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity, indirect light, and warm temperatures (65–75°F or 18–24°C).
Medium
Well-draining potting mix with perlite or sand.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a plastic cover; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Remove spent flowers to encourage reblooming; trim leggy stems to maintain shape.
Tools
Clean pruning shears or scissors.
Checklist
Sanitize tools, prune dead flowers, trim leggy growth, shape plant gently.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
One size larger pot; ensure good drainage holes.
Method
Remove plant gently, trim roots if needed, place in a new pot with fresh soil, water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil refreshment.
Checklist
Check root bound status, prepare new pot, trim roots if necessary, use fresh soil, water lightly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, avoid foliage wetting
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 in the morning to reduce evaporation.
Watering Schedule Tips
Water thoroughly when the top inch of soil feels 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 browning leaf edges.
Cold Stress
Slows growth, may cause leaf discoloration, and increases susceptibility to root rot.
Solution: Move to a warmer location, insulate pots, and reduce watering during cold spells.
Hot Stress
Leaves may scorch, wilt, or drop; growth may become stunted.
Solution: Provide shade, increase humidity, and water more frequently during heatwaves.
Fertilizing Guide
Fertilizing Checklist
Check growth phase, dilute fertilizer, apply to soil, avoid foliage contact
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during the growing season (spring to early fall); avoid fertilizing in winter.
