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
partial shade to full sun with protection from intense afternoon sun
Rotate plant for even growth; use sheer curtains to filter intense light; avoid sudden light changes.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure soil dries between waterings; avoid overwatering.
Soil
well-draining, humus-rich soil with added compost
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid compacted soil; topdress with compost annually.
Temperature
Prefers 60–75°F (15–24°C); cooler temperatures (50–60°F or 10–15°C) are acceptable during dormancy.
Avoid sudden temperature shifts; protect from frost; ensure good air circulation.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid overfertilizing.
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.
- Apply rooting hormone.
- Plant in medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (65–75°F or 18–24°C), and indirect light.
Medium
Well-draining mix of peat, perlite, and sand; can also use pure sand or vermiculite.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots may develop in 3–6 weeks; new growth may take 2–4 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic wrap or propagator.
Quick Tips
Use healthy, non-flowering stems; keep medium consistently moist; provide bottom heat if possible.
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 dead or diseased parts.
Tools
Pruning shears, sterilized scissors, gloves.
Checklist
Sterilize tools; prune during dormancy; remove dead/diseased parts; shape as desired.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
Choose a pot 1–2 inches larger in diameter than the current one.
Method
Remove plant gently; trim roots if needed; place in new pot with fresh soil; water lightly.
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 with drainage; use fresh soil mix; water after repotting.
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 thoroughly when the top 1–2 inches of soil are dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add compost or well-rotted manure for fertility; mix in perlite or sand for drainage.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in extreme heat; leaf drop or browning in cold stress.
Cold Stress
Slows growth; may cause leaf discoloration or dieback in prolonged cold.
Solution: Move to a warmer location; insulate roots with mulch; avoid cold drafts.
Hot Stress
Leaves may wilt, scorch, or drop; growth may slow in excessive heat.
Solution: Provide shade; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; rinse between feedings.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
