Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; tolerates partial shade, especially in hot climates.
Sunlight Tolerance Tips:
Acclimate gradually to intense light; protect from direct midday sun to prevent scorching; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant for even light exposure; use sheer curtains to filter intense sunlight; monitor for signs of light stress.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering.
Soil
well-draining, loamy soil with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid compacted soil; refresh soil every 2 years.
Temperature
Prefers 60–75°F (15–24°C); tolerates cooler temperatures but avoid frost.
Avoid sudden temperature changes; protect from drafts; maintain consistent room temperature.
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 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; can also root in water initially.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots may develop in 2–4 weeks; new growth in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity with a plastic cover; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth; cut just above a leaf node or bud.
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/diseased parts; 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 roots if necessary; place in a 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
Check root bound status; prepare new pot with drainage; trim roots if needed; use fresh soil.
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 moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
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 like compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in extreme heat or cold; leaf drop in cold stress.
Cold Stress
Slows growth, may cause leaf discoloration, and increases susceptibility to disease in temperatures below 50°F (10°C).
Solution: Move to a warmer location; provide a heat source if necessary; avoid drafts and cold windowsills.
Hot Stress
Leaves may wilt, curl, or develop brown edges; growth may slow in temperatures above 85°F (29°C).
Solution: Increase humidity with misting or a humidifier; provide shade during peak heat; ensure adequate watering.
Fertilizing Guide
Fertilizing Checklist
Check season; dilute fertilizer; apply to moist soil; avoid contact with leaves.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring to early fall); avoid fertilizing in winter.
