Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate some direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate plants gradually to direct sunlight; protect from intense midday sun to prevent scorching; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
easyeasy
Sunlight
partial shade to full sun
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid placing near west-facing windows in summer.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom; allow soil to dry between waterings; avoid overwatering.
Soil
well-draining, sandy loam with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; top-dress with compost annually.
Temperature
Prefers 65–85°F (18–29°C); tolerates mild fluctuations but avoid prolonged exposure to extreme heat or cold.
Avoid placing near drafty windows or heating vents; maintain consistent room temperature; monitor for signs of stress.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; reduce frequency in dormant periods.
Propagation
Methods
Stem cuttings in water or soil.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting with at least one node.
- 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; maintain consistent moisture.
Medium
Well-draining potting mix or water with occasional changes.
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; keep cuttings out of direct sun; change water regularly if using water propagation.
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
Sterilize tools; prune during active growth; remove dead or diseased stems; shape as desired.
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 any circling roots; place in a new pot with fresh soil; water lightly after repotting.
Suggestions
Repot every 1–2 years or when roots fill the pot; beneficial for growth and soil freshness.
Checklist
Select appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency seasonally.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; 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 to improve drainage; incorporate organic matter like compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or yellowing leaves in cold; scorching or stunted growth in excessive heat.
Cold Stress
Slows growth, may cause leaf drop, and increases susceptibility to root rot due to reduced water uptake.
Solution: Move to a warmer location; protect from drafts; reduce watering during cold periods.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to excessive water loss.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during active growth; 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 and summer); avoid fertilizing in winter.
