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 gradually to direct light; protect from intense afternoon sun; 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 harsh light; avoid direct afternoon sun.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but allow soil to dry between waterings; avoid overwatering, especially in winter.
Soil
well-draining, sandy or loamy soil with low fertility
pH: 5.5–6.5
Ensure soil is not compacted; avoid heavy clay soils; use a mix with good aeration.
Temperature
Prefers temperatures between 60–75°F (15–24°C); can tolerate cooler temperatures but avoid frost.
Avoid sudden temperature changes; protect from drafts; maintain consistent warmth in winter.
Fertilizing
every 2 months during spring and summer, none in winter
Dilute fertilizer to prevent burn; fertilize only during active growth; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in medium.
- Keep moist and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity, indirect light, and warm temperatures (65–75°F or 18–24°C).
Medium
Well-draining mix of perlite and peat moss
Hormone
Recommended to use rooting hormone for better success.
Timeline
Roots may develop in 4–8 weeks; establish in new pot after 3–4 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a plastic bag; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Selective pruning of stems to shape the plant and promote new growth.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or overgrown stems.
Tools
Pruning shears, sterilizing solution
Checklist
Sterilize tools; prune dead or damaged stems; shape the plant; clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure good drainage.
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; may need repotting if growth slows or soil dries out quickly.
Checklist
Choose appropriate pot; prepare new soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure proper drainage; adjust for season.
How to Apply Water Properly
Water deeply at the root zone until water drains from the bottom; ensure excess water is removed to prevent waterlogging.
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 sand for drainage; incorporate peat moss for acidity; use a cactus or succulent mix as a base.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or browning leaf edges in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf drop, and can lead to root damage in freezing temperatures.
Solution: Move to a warmer location; protect from drafts; avoid sudden temperature drops.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow in excessively high temperatures.
Solution: Provide shade during peak heat; increase humidity; ensure adequate watering.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; dilute properly; fertilize during growing season; avoid winter.
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.
