Care Requirements
Care Difficulty
easyeasy
Sunlight
partial shade to full sun
Avoid direct midday sun; rotate plant for even growth; provide shade during peak heat.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly but infrequently; ensure proper drainage; avoid wetting foliage.
Soil
well-draining, loamy soil with moderate organic content
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; topdress with compost annually.
Temperature
Prefers 65–75°F (18–24°C); tolerates mild fluctuations but avoid prolonged exposure to extremes.
Protect from frost; avoid sudden temperature changes; maintain moderate warmth.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer
Dilute fertilizer to prevent burn; fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings in water or moist soil.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Place in medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid, and bright indirect light; protect from direct sun.
Medium
Well-draining soil mix or water with occasional changes.
Hormone
Optional but can speed up rooting.
Timeline
Roots typically form in 2–4 weeks; new growth in 6–8 weeks.
Tools Needed
Pruners, rooting hormone (optional), small pots, water or soil mix.
Quick Tips
Use healthy, non-flowering stems; keep consistently moist; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Remove dead or leggy growth to encourage bushier, healthier plants.
Tools
Clean, sharp pruners or scissors.
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
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 1–2 years or when roots fill the pot; beneficial for growth and health.
Checklist
Check root bound status; prepare new pot with drainage; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting leaves.
How to Apply Water Properly
Water directly at the root zone until water drains from the bottom; allow excess to drain away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply 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 for fertility.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or yellowing in cold; scorching or stunted growth in excessive heat.
Cold Stress
Slows growth, causes leaf drop, and may lead to root damage in freezing conditions.
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 due to excessive transpiration.
Solution: Provide shade; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; avoid contact with leaves.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
