Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to lower light in winter if necessary.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense light; protect from direct sun to avoid scorching; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid sudden light changes.
Watering
N/A, aquatic plant
Water thoroughly until it drains from the bottom; allow soil to dry partially between waterings; avoid wetting foliage.
Soil
N/A, grows in water
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use pots with drainage holes; avoid compacted soil; refresh soil annually.
Temperature
Prefers 65–75°F (18–24°C); tolerates slight fluctuations but avoid extremes.
Avoid placing near drafty windows; maintain consistent room temperature; monitor for signs of stress.
Fertilizing
N/A, nutrient uptake from water
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; adjust frequency based on growth rate.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a healthy cutting.
- Apply rooting hormone if using.
- Plant in medium.
- Maintain humidity.
- Wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity, indirect light, and warm temperatures (70–75°F) for successful rooting.
Medium
Well-draining potting mix with perlite or sand for better aeration.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 3–4 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; keep soil consistently moist; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Snip stems just above a leaf node; remove yellow or dead leaves at the base.
Pruning Plan
Remove dead or leggy growth to encourage bushier, healthier plants; maintain shape and air circulation.
Tools
Clean pruning shears, gloves, disinfectant for tools.
Checklist
Sanitize tools; prune dead growth; shape the plant; clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Choose a pot one size larger (1–2 inches wider) than the current one.
Method
Remove plant gently; trim roots if needed; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots outgrow the pot; promotes fresh soil and root health.
Checklist
Select new pot; prepare fresh soil; handle roots carefully; water 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 directly at the root zone, ensuring even saturation; water early in the morning to minimize evaporation; ensure excess water drains away to prevent waterlogging.
Watering Schedule Tips
Water deeply once 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 for fertility; ensure proper aeration.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, wilting, or bud drop; stunted growth in extreme conditions.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage in prolonged cold.
Solution: Move to a warmer location; insulate pots; avoid cold drafts; reduce watering.
Hot Stress
Leaf scorch, wilting, and dehydration; may drop leaves to conserve water.
Solution: Provide shade; increase humidity; water more frequently; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute properly; apply during growing season; avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season; avoid fertilizing in winter.
