Care Details
Ideal Sunlight Coverage:

Sunlight Tolerance Tips:
Acclimate gradually to direct light; protect from intense sun to prevent scorching; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
easyeasy
Sunlight
partial shade to full shade
Rotate plant for even growth; use sheer curtains to filter harsh light; move outdoors in spring/summer for stronger light.
Watering
every 7–10 days during active growth, reduce in winter
Allow soil to dry between waterings; avoid overwatering; ensure good drainage.
Soil
well-draining, peaty potting mix
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 60–75°F (15–24°C); tolerates mild fluctuations but avoid prolonged exposure to extremes.
Avoid placing near drafty windows; use a humidifier in dry heat; shield from direct sun in summer.
Fertilizing
every 4–6 weeks during growing season, none in winter
Dilute fertilizer to prevent burn; fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings in water or soil; leaf cuttings also viable but slower.
Step-by-Step Propagation Guide
- Take 3–4 inch cutting.
- Remove lower leaves.
- Place in medium.
- Keep moist and warm.
Best Time: Spring or early summer when plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain consistent moisture.
Medium
Well-draining mix like perlite and peat moss, or water for initial rooting.
Hormone
Optional but can speed up rooting; rooting powder or gel recommended.
Timeline
Roots in 2–4 weeks; establish in new pot within 6–8 weeks.
Tools Needed
Sharp scissors, rooting hormone, small pots, plastic wrap (for humidity).
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; maintain humidity for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth; cut just above a leaf node.
Pruning Plan
Regular pruning to maintain shape, encourage bushiness, and remove leggy growth.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sanitize tools; prune dead/damaged growth; shape as desired; dispose of clippings.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter); ensure good drainage.
Method
Remove plant gently; trim roots if needed; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 1–2 years or when roots fill the pot; beneficial for growth and soil freshness.
Checklist
Choose appropriate pot; prepare fresh soil; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; adjust for season.
How to Apply Water Properly
Water deeply at the root zone until water drains from the bottom; avoid wetting foliage; water in the morning to reduce evaporation.
Watering Schedule Tips
Water thoroughly when the top 1–2 inches of soil are 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
Yellowing leaves, wilting, or stunted growth in cold; leaf drop or scorching in excessive heat.
Cold Stress
Slows growth, causes leaf drop, and may lead to root rot in cold, damp conditions.
Solution: Move to a warmer location; protect from drafts; reduce watering in cool conditions.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to excessive heat and dryness.
Solution: Provide shade; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; avoid foliage contact.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
