Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; adjust to lower light in winter if needed.
Sunlight Tolerance Tips:
Acclimate to brighter light gradually; protect from direct sun to avoid leaf burn; place in a spot with filtered light for best growth.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
bright, indirect light
Rotate plant monthly for even growth; use sheer curtains to filter direct sunlight; avoid placing near south-facing windows in summer.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Allow soil to dry partially between waterings; avoid overwatering; ensure proper drainage.
Soil
well-draining, peat-based potting mix
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 65–80°F (18–27°C); tolerates slight fluctuations but dislikes drafts or extreme heat.
Avoid placing near vents or windows with extreme temperature changes; maintain consistent room temperature.
Fertilizing
every 4–6 weeks during active growth (spring and summer), none in winter
Dilute fertilizer to prevent burn; fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings with at least one node.
Step-by-Step Propagation Guide
- Select healthy stem, cut below node, apply hormone, place in medium, maintain humidity, wait for roots.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (70–75°F), indirect light.
Medium
Well-draining mix of peat and perlite or coarse sand.
Hormone
Recommended to encourage root development.
Timeline
Roots in 3–6 weeks; establish in 2–3 months.
Tools Needed
Sharp scissors, rooting hormone, propagation tray, plastic wrap, misting bottle.
Quick Tips
Use healthy, non-flowering stems; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a leaf node or junction; remove entire leaves at the base.
Pruning Plan
Remove yellow or damaged leaves to maintain appearance and health; shape plant to encourage bushier growth.
Tools
Clean, sharp scissors or pruning shears, gloves.
Checklist
Sanitize tools, cut at correct angle, remove damaged leaves, clean up debris, monitor for regrowth.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure drainage holes.
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 outgrow the pot; promotes fresh soil and root space.
Checklist
Check root bound status, prepare new pot, trim roots, add fresh soil, water sparingly, place in shade temporarily.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture, water thoroughly, ensure drainage, avoid foliage wetting, adjust for season.
How to Apply Water Properly
Water deeply until it drains from the bottom, ensuring moisture reaches the root zone; avoid wetting foliage to prevent fungal issues; water in the morning for optimal absorption.
Watering Schedule Tips
Water thoroughly when the top 1–2 inches of soil feel dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; aerate with a fork if compacted.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, leaf drop, stunted growth, or brown leaf tips.
Cold Stress
Slows growth, causes leaf discoloration, and may lead to root rot due to reduced water uptake.
Solution: Move to a warmer location, avoid cold drafts, and reduce watering during cold periods.
Hot Stress
Wilting, leaf scorch, or leaf drop due to excessive transpiration and water loss.
Solution: Provide shade, increase humidity, and water more frequently during hot spells.
Fertilizing Guide
Fertilizing Checklist
Check growth phase, dilute fertilizer, apply to moist soil, avoid foliage contact, flush periodically.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
