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, allowing soil to dry between waterings
Water thoroughly but allow soil to dry between waterings; avoid overwatering, especially in winter.
Soil
well-draining, sandy or loamy soil with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid compacted soil.
Temperature
Prefers moderate temperatures between 60–75°F (15–24°C); can tolerate cooler temperatures but avoid frost.
Avoid sudden temperature changes; keep away from heating/cooling vents.
Fertilizing
every 2–3 months during active growth with a balanced, diluted fertilizer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting, 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 for better aeration.
Hormone
Rooting hormone can be used but is not strictly necessary.
Timeline
Roots typically form in 2–4 weeks; new growth may take 1–2 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining mix.
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 to promote branching.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or leggy stems.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sanitize tools, prune dead/leggy stems, shape as desired, clean up debris.
Repotting Guide
Best Season
Spring, when the plant is entering its active growth phase.
Pot Size
Choose a pot one size larger (1–2 inches wider) than the current one.
Method
Remove plant gently, trim roots if necessary, place in a new pot with fresh soil, water lightly.
Suggestions
Repot every 1–2 years or when roots outgrow the pot; beneficial for growth and health.
Checklist
Check root bound status, prepare new pot, trim roots if needed, use fresh soil, water lightly.
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 until water drains from the bottom; ensure excess water is removed to prevent standing moisture.
Watering Schedule Tips
Water when the top inch of soil is 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
Wilting, yellowing leaves, or stunted growth in extreme heat or cold.
Cold Stress
Slows growth and can cause leaf drop or browning in prolonged cold.
Solution: Move to a warmer location; protect from drafts and cold windows.
Hot Stress
Leaves may wilt, curl, or develop brown edges in excessive heat.
Solution: Provide shade during peak heat; increase humidity and ensure adequate water.
Fertilizing Guide
Fertilizing Checklist
Check growth phase, use diluted fertilizer, avoid winter feeding, flush soil periodically.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
