Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate gradually to direct sunlight; protect from intense afternoon sun to prevent leaf scorch; adjust indoor placement to mimic natural light conditions.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter intense light.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but allow soil to dry between waterings; avoid overwatering, especially in cool conditions.
Soil
well-draining, loamy soil with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil is not compacted; avoid heavy clay soils.
Temperature
Prefers warm temperatures between 65–85°F (18–29°C); thrives in tropical conditions.
Avoid sudden temperature changes; maintain consistent warmth; protect from cold 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.
Propagation
Methods
Stem cuttings in water or soil.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Place 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.
Medium
Well-draining potting mix or water with occasional root hormone application.
Hormone
Optional but can speed up rooting.
Timeline
Roots typically form in 2–4 weeks; new growth may take 1–2 months.
Tools Needed
Pruning shears, rooting hormone (optional), small pots or jars, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased parts.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; prune during active growth; remove dead or crossing branches.
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 crowded; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and health.
Checklist
Use fresh potting mix; ensure good drainage; handle roots carefully.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water thoroughly; ensure proper drainage.
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 deeply once 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.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, wilting, or stunted growth in cold; leaf drop or scorching in excessive heat.
Cold Stress
Low temperatures slow growth and can cause root damage or death; may enter dormancy.
Solution: Move to a warmer location; protect from drafts; use a heat mat if necessary.
Hot Stress
Excessive heat can cause leaf scorch, dehydration, and wilting; may lead to reduced flowering.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during growing season; avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring and summer); reduce or stop in fall and winter.
