Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to morning sun in winter and dappled shade in summer.
Sunlight Tolerance Tips:
Gradually acclimate to direct light to avoid scorching; place in filtered light outdoors and bright indirect indoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to filtered light
Rotate plant weekly for even growth; use sheer curtains to filter intense light.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly but allow soil to dry between waterings; avoid wetting foliage to prevent fungal issues.
Soil
well-draining, peat-based potting mix with added perlite or sand
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes, avoid compacted soil, top-dress with compost annually.
Temperature
Ideal range 65–75°F (18–24°C); prefers stable temperatures, cooler in winter but above 50°F (10°C).
Avoid drafts, maintain stable temps, use room heaters/fans cautiously.
Fertilizing
every 2–4 weeks during active growing season (spring and summer), with balanced liquid fertilizer diluted to half strength
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings in soil or water.
Step-by-Step Propagation Guide
- Take cutting, remove lower leaves, apply hormone (optional), plant in medium, maintain humidity.
Best Time: Spring or early summer when growth is active.
Environment
High humidity, indirect light, and warm temperatures (70–75°F or 21–24°C).
Medium
Well-draining mix like peat and perlite or water with occasional nutrient additions.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots in 2–4 weeks; establish in 2–3 months.
Tools Needed
Pruners, rooting hormone, small pots, plastic bags or propagator.
Quick Tips
Use healthy parent stems, keep soil moist but not waterlogged, provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips, cut just above a leaf node or bud, remove dead/damaged stems.
Pruning Plan
Remove leggy growth, spent flowers, and yellow leaves to encourage bushier growth and prevent disease.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sterilize tools, prune dead/diseased parts, make clean cuts, dispose of clippings.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure good drainage.
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 soil freshness.
Checklist
Choose right pot, prepare new soil, handle roots carefully, water after repotting.
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 until water drains from the bottom; ensure excess water is removed 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 compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Leaf drop, wilting, or yellowing in cold; stunted growth or leaf burn in excessive heat.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root rot due to reduced water uptake.
Solution: Move to a warmer spot, insulate pots, and reduce watering to prevent cold-related rot.
Hot Stress
Leaves may wilt, curl, or develop brown edges; growth may slow due to excessive transpiration.
Solution: Provide shade, increase humidity, and water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check season, dilute fertilizer, water before feeding, avoid foliage contact
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
