Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to morning sun exposure in summer to prevent scorching.
Sunlight Tolerance Tips:
Gradually acclimate to brighter light, protect from intense afternoon sun, place in a spot with filtered light if outdoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter direct sun; avoid 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 wetting foliage.
Soil
well-drained, sandy loam with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a pot with drainage holes; avoid heavy clay soils; top-dress with compost annually.
Temperature
Prefers 60–75°F (15–24°C); cooler temperatures (50–60°F) at night promote better growth.
Avoid sudden temperature changes; keep away from drafty areas; maintain consistent room temperature.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup; avoid over-fertilizing.
Propagation
Methods
Stem cuttings or seed propagation.
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 (70–80%), warm temperatures (65–75°F), indirect light.
Medium
Well-draining mix of peat and perlite or cactus soil.
Hormone
Rooting hormone is recommended for faster root development.
Timeline
Roots typically form in 3–6 weeks; new growth may take 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth, cut stems just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove spent flowers or damaged foliage.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sanitize tools, prune dead/damaged growth, 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.
Method
Remove plant gently, trim roots if necessary, place in a new pot with fresh soil, water lightly.
Suggestions
Repot every 1–2 years or when roots outgrow the pot; promotes fresh soil and root health.
Checklist
Choose appropriate pot, prepare new soil, inspect roots, water after repotting, place in shade for a day.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, avoid leaf wetting.
How to Apply Water Properly
Water directly at the root zone, ensure even moisture penetration, allow excess water to drain, 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 sand for drainage, incorporate compost for fertility, ensure aeration with organic matter.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, yellowing, or stunted growth.
Cold Stress
Slows growth, may cause leaf discoloration or dieback in prolonged cold.
Solution: Move to a warmer location, insulate pots, avoid cold drafts, use a heat mat if necessary.
Hot Stress
Leaves may scorch, wilt, or drop; growth may stall in excessive heat.
Solution: Provide shade, increase humidity, water more frequently, ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type, dilute properly, apply during growing season, avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
