Care Details
Ideal Sunlight Coverage:
Full sun to partial shade (4–6 hours of direct sunlight daily); tolerates some shade in hot climates.
Sunlight Tolerance Tips:
Acclimate gradually to direct sunlight to prevent leaf burn; provide shade during peak afternoon heat in hot regions; adjust light exposure based on seasonal changes.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
Full sun to partial shade
Avoid sudden light changes; use sheer curtains for filtered light; rotate plant for even growth.
Watering
Consistent water level maintenance, ensuring the crown remains submerged 5–15 cm below the water surface
Water thoroughly until runoff; allow soil to dry slightly between waterings; avoid waterlogging.
Soil
Not applicable; grows in water
pH: Slightly acidic to neutral (pH 6.0–7.0).
Avoid heavy clay soils; ensure good aeration; test pH periodically.
Temperature
Prefers warm temperatures (65–85°F / 18–29°C); thrives in summer warmth but can tolerate mild frosts.
Monitor temperature fluctuations; protect from drafts; adjust care based on seasonal changes.
Fertilizing
Every 4–6 weeks during active growing season with aquatic plant fertilizer
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; match fertilizer to plant's growth stage.
Propagation
Methods
Stem cuttings or division of rhizomes; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a healthy stem cutting with at least 2 nodes.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%); warm temperatures (70–75°F / 21–24°C); indirect light.
Medium
Sphagnum moss or a mix of peat and perlite; keep consistently moist.
Hormone
Rooting hormone is optional but can improve success rates.
Timeline
Roots may develop in 2–4 weeks; new growth typically appears within 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, propagation tray, humidity dome.
Quick Tips
Use clean tools to prevent disease; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Use clean, sharp tools to make clean cuts; prune just above a leaf node or bud.
Pruning Plan
Remove dead or yellowing leaves to maintain plant health and appearance; trim back overgrown stems to encourage bushier growth.
Tools
Pruning shears, sharp knife, disinfectant.
Checklist
Check for dead/damaged leaves; sterilize tools; prune selectively; dispose of clippings.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Choose a pot one size larger than the current one (e.g., +2–3 inches in diameter).
Method
Gently remove the plant; trim any circling roots; place in a new pot with fresh soil; water thoroughly after repotting.
Suggestions
Repot every 2–3 years or when the plant becomes root-bound; beneficial for rejuvenation and growth.
Checklist
Select appropriate pot; prepare new soil; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring even moisture distribution to the root zone; water early in the morning to minimize evaporation; ensure excess water drains away to prevent stagnation.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add compost or well-rotted manure to enhance fertility; incorporate perlite or sand for better drainage; mulch to retain moisture.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves (cold stress); wilting or leaf drop (heat stress); stunted growth.
Cold Stress
Low temperatures slow growth and may cause leaf discoloration or dieback; prolonged cold can damage roots.
Solution: Move to a warmer location; provide frost protection in cold climates; avoid overwatering in cool conditions.
Hot Stress
Excessive heat can lead to leaf scorch, wilting, and reduced flowering; may cause water stress.
Solution: Provide shade during peak heat; increase watering frequency; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute correctly; apply during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring to early fall); avoid fertilizing in winter.
