Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate 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 growth; use sheer curtains to filter intense light; move outdoors in spring/summer for stronger light.
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, loamy soil with added organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix with good drainage; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Prefers 60–75°F (15–24°C); tolerates cooler temperatures but avoid frost; thrives in moderate warmth with good air circulation.
Avoid sudden temperature changes; protect from drafts; maintain moderate warmth year-round.
Fertilizing
every 4–6 weeks during spring and summer
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; stop fertilizing in fall/winter.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a healthy cutting, apply rooting hormone, plant in medium, keep moist, provide warmth and indirect light.
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
Rooting hormone is optional but recommended for faster rooting.
Timeline
Roots may develop in 3–6 weeks; new growth may take 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining medium.
Quick Tips
Use healthy, non-flowering stems; keep cuttings out of direct sun; maintain humidity with a plastic bag if needed.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth, cut back leggy stems, remove dead or yellowing leaves.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased parts.
Tools
Clean, sharp pruning shears or scissors, disinfectant for tools.
Checklist
Disinfect tools, prune dead/diseased parts, shape the plant, clean up debris.
Repotting Guide
Best Season
Early spring before active growth starts.
Pot Size
Increase pot size by 1–2 inches in diameter; avoid oversized pots.
Method
Use fresh well-draining soil, gently tease out roots, place in a slightly larger pot, water lightly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil freshness.
Checklist
Check root bound status, prepare new pot, use fresh soil, handle roots carefully, water lightly.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water deeply, ensure drainage, adjust for season.
How to Apply Water Properly
Water directly at the root zone, ensure even moisture distribution, allow excess water to drain, water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply once 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 compost for fertility, ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or leaf drop in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf discoloration or dieback if exposed to prolonged cold below 50°F (10°C).
Solution: Move to a warmer location, insulate pots, avoid cold drafts, protect from frost.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow in excessive heat above 85°F (29°C).
Solution: Provide shade, increase humidity, water more frequently, ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check season, dilute fertilizer, water before feeding, avoid over-fertilizing.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
