Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; avoid direct sunlight which can scorch leaves.
Sunlight Tolerance Tips:
Acclimate gradually to new light conditions; place in east-facing windows or under sheer curtains for filtered light.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant weekly for even growth; use sheer blinds to diffuse intense light.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly but allow soil to dry partially between waterings; avoid waterlogging.
Soil
well-draining, peat-based potting mix
pH: Slightly acidic to neutral (pH 5.5–6.5).
Ensure pots have drainage holes; avoid compacted soil; refresh topsoil annually.
Temperature
Prefers 65–80°F (18–27°C); cooler temperatures (55–60°F or 13–15°C) at night are beneficial.
Avoid placing near drafty windows or heating vents; maintain stable temperatures for optimal growth.
Fertilizing
every 2 weeks during active growth (spring and summer), with a balanced liquid fertilizer diluted to half strength
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings with leaf nodes; can also propagate via division in spring.
Step-by-Step Propagation Guide
- Take 3–4 inch cuttings.
- Remove lower leaves.
- Dip in hormone (optional).
- Plant in medium.
- Maintain humidity.
Best Time: Spring or early summer when plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (70–75°F or 21–24°C), and indirect light.
Medium
Peat-based mix with perlite or sand for good drainage.
Hormone
Rooting hormone is optional but can speed up rooting.
Timeline
Roots develop in 3–6 weeks; new growth appears in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic bags or propagator.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushiness; cut just above leaf nodes to promote branching.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove leggy or dead stems.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; prune dead/damaged stems; shape plant; clean up debris.
Repotting Guide
Best Season
Spring, before new growth begins.
Pot Size
Increase pot size by 1–2 inches in diameter; avoid oversized pots.
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 root health and growth.
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 thoroughly; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring even moisture distribution without wetting foliage; allow excess water to drain completely.
Watering Schedule Tips
Water when the top inch of soil feels 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
Leaf drop, wilting, or stunted growth in extreme heat or cold.
Cold Stress
Slows growth and may cause leaf damage or dieback in temperatures below 50°F (10°C).
Solution: Move to a warmer location; insulate pots in cold drafts; avoid sudden temperature drops.
Hot Stress
Leaves may wilt, curl, or develop brown edges in excessive heat above 85°F (29°C).
Solution: Increase humidity; provide shade; ensure adequate ventilation; water more frequently if heat persists.
Fertilizing Guide
Fertilizing Checklist
Check season; dilute fertilizer; apply to moist soil; rinse pot periodically.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
