Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; tolerates partial shade, especially in hot climates.
Sunlight Tolerance Tips:
Acclimate new plants gradually to direct sun; protect from intense midday sun to prevent scorching; adjust indoor placement to mimic natural light patterns.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to full sun
Rotate plant weekly for even growth; use sheer curtains to filter harsh light; avoid placing near hot windows.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly until it drains from the bottom; ensure soil dries moderately between waterings; avoid waterlogging.
Soil
moist, well-draining, fertile loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix with good water retention but no standing water; avoid compacted soil; refresh top layer annually.
Temperature
Prefers 60–75°F (15–24°C); cooler temperatures (50–60°F or 10–15°C) during dormancy in winter.
Monitor room temperature; use a humidifier in dry environments; shield from drafts.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid over-fertilizing.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain consistent moisture.
Medium
Well-draining potting mix with perlite or sand; can also root in water.
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, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity with a plastic bag; avoid direct sun.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node; remove yellow or damaged leaves.
Pruning Plan
Remove dead or leggy stems to encourage bushier growth; shape plant for aesthetic appeal.
Tools
Clean pruning shears or scissors, gloves.
Checklist
Sanitize tools; prune dead/damaged growth; shape as desired; dispose of clippings.
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 crowded; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for rejuvenation and fresh soil.
Checklist
Select appropriate pot; prepare fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture with finger; water thoroughly; ensure drainage; adjust seasonally.
How to Apply Water Properly
Water directly at the root zone, ensuring even moisture distribution; water deeply to encourage root growth; allow excess water to drain completely; water in the morning to reduce evaporation and fungal risk.
Watering Schedule Tips
Water consistently during active growth (spring/summer), allowing soil to dry slightly between waterings; reduce frequency in fall/winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure aeration with chunky materials.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or chlorosis in excessive heat; stunted growth or browning leaf edges in cold stress.
Cold Stress
Slows metabolic processes, leading to reduced growth and potential frost damage in freezing conditions.
Solution: Move to a warmer location; provide frost protection in cold climates; avoid cold drafts and sudden temperature drops.
Hot Stress
Causes leaf scorch, wilting, and dehydration due to excessive transpiration.
Solution: Increase humidity, provide shade, and water more frequently; avoid placing near heat sources.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer correctly; apply to moist soil; stop in dormant season.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during spring/summer; cease fertilizing in fall/winter.
