Care Requirements
Care Difficulty
easyeasy
Sunlight
partial shade to filtered light
Rotate plant for even growth; use sheer curtains for direct light; adjust for seasonal light changes.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water deeply but infrequently; ensure good drainage; avoid waterlogging.
Soil
well-draining, loamy soil with added organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; test pH if issues arise.
Temperature
Prefers 65–85°F (18–29°C); cooler temperatures in winter (55–65°F) may induce dormancy.
Avoid sudden temperature changes; protect from drafts; maintain stable indoor temperatures.
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 in water or 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 in 2–4 weeks; establish in 2–3 months.
Tools Needed
Pruners, rooting hormone (optional), small pots, water or soil medium.
Quick Tips
Use healthy, non-flowering stems; maintain humidity around cuttings; change water regularly if using water propagation.
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; shape as needed.
Tools
Clean, sharp pruners or scissors.
Checklist
Sanitize tools; prune dead/damaged growth; shape plant; dispose of clippings.
Repotting Guide
Best Season
Spring, before the main growing season.
Pot Size
One size larger pot; ensure good drainage holes.
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 outgrow the pot; promotes fresh soil and growth.
Checklist
Check root bound status; prepare new pot; use fresh soil; 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 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 thoroughly 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 stunted growth in extreme heat or cold; yellowing leaves in sudden temperature shifts.
Cold Stress
Slows growth; may cause leaf drop or root damage in prolonged cold below 50°F (10°C).
Solution: Move to a warmer location; insulate pots; avoid cold drafts; protect from frost.
Hot Stress
Leaf scorch, wilting, or dehydration in temperatures above 90°F (32°C); may drop leaves to conserve water.
Solution: Provide shade; increase humidity; water more frequently; use shade cloth outdoors.
Fertilizing Guide
Fertilizing Checklist
Check season; 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.
