Care Details
Ideal Sunlight Coverage:
Bright indirect light or partial shade; 4–6 hours of filtered sunlight daily; adjust for intense summer sun.
Sunlight Tolerance Tips:
Acclimate gradually to direct sun to avoid scorching; protect from harsh afternoon sun; 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 intense light; avoid direct midday sun.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water deeply but infrequently; ensure soil dries between waterings; avoid overwatering.
Soil
well-draining, loamy soil with some organic matter
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 50–75°F (10–24°C); tolerates cooler temperatures but avoid prolonged frost.
Avoid sudden temperature changes; protect from frost; maintain moderate humidity.
Fertilizing
every 4–6 weeks during spring and summer, none in winter
Dilute fertilizer to prevent burn; fertilize during active growth; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings with nodes; can also propagate via layering.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting with nodes.
- 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 (70–90%), warm temperatures (65–75°F), indirect light.
Medium
Peat-based mix with perlite or sand for drainage.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 4–6 weeks; new growth appears in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic wrap or propagator.
Quick Tips
Use healthy, non-flowering stems; maintain humidity with a cover; keep out of direct sun.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushiness; cut stems just above a leaf node or bud.
Pruning Plan
Shape the plant, encourage bushier growth, and remove dead or overgrown stems.
Tools
Pruning shears, sharp scissors, gloves.
Checklist
Sanitize tools; prune dead/damaged growth; shape as desired; dispose of clippings.
Repotting Guide
Best Season
Spring, before the active growing season 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 2–3 years or when roots fill the pot; necessary if growth slows or soil degrades.
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 perlite or coarse sand for drainage; incorporate organic matter like compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves (cold stress), wilting or leaf drop (heat stress), stunted growth.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root damage in freezing conditions.
Solution: Move to a warmer location; insulate roots with mulch; avoid cold drafts.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to excessive heat.
Solution: Provide shade; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check season; dilute fertilizer; apply to moist soil; avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength; feed monthly during growing season (spring to early fall); avoid fertilizing in winter.
