Care Requirements
Care Difficulty
moderateeasy
Sunlight
partial shade to filtered light
Rotate plant weekly; use sheer curtains for direct light; move outdoors in spring/summer for stronger light.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure proper drainage; adjust based on season and humidity.
Soil
well-draining, fertile potting mix with added organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix of peat, perlite, and potting soil; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Prefers 65–80°F (18–27°C); tolerates mild fluctuations but avoid drafts or extreme heat.
Avoid sudden temperature changes; maintain stable conditions; protect from drafts.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer
Fertilize only when actively growing; 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 potting mix or water with occasional changes.
Hormone
Optional but can speed up rooting.
Timeline
Roots develop in 2–4 weeks; new growth in 6–8 weeks.
Tools Needed
Sharp scissors, rooting hormone (optional), small pots or jars.
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
Prune to maintain shape, encourage bushiness, and remove dead/damaged growth.
Tools
Clean, sharp scissors or pruning shears.
Checklist
Sanitize tools; prune in early morning; remove dead/diseased parts; shape evenly.
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 fresh soil with good drainage.
Suggestions
Repot every 1–2 years or when roots outgrow the pot; beneficial for growth and health.
Checklist
Check root bound status; prepare new pot with drainage; use fresh soil; 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 directly at the root zone until water drains from the bottom; avoid wetting foliage; 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 for fertility; ensure proper aeration.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, wilting, or leaf drop; stunted growth in extreme conditions.
Cold Stress
Slows growth; may cause leaf discoloration or damage in prolonged cold below 50°F (10°C).
Solution: Move to a warmer spot; insulate from drafts; avoid cold water during watering.
Hot Stress
Wilting, leaf scorch, or leaf drop in excessive heat above 90°F (32°C).
Solution: Provide shade; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; stop in dormant season.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
