Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate some direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate gradually to direct sun; protect from intense midday sun; adjust placement based on indoor/outdoor conditions.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter intense light; move outdoors in spring/summer for stronger light.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom; allow soil to dry between waterings; avoid overwatering.
Soil
well-draining, fertile, slightly acidic soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a pot with drainage holes; avoid heavy clay soils; topdress with compost annually.
Temperature
Prefers 65–85°F (18–29°C); cooler in winter (50–60°F/10–15°C) to encourage dormancy.
Avoid sudden temperature changes; protect from cold drafts; maintain moderate warmth year-round.
Fertilizing
every 4–6 weeks during growing season
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; avoid overfertilizing.
Propagation
Methods
Stem cuttings or seeds; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Apply rooting hormone.
- Plant in medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (75–85°F/24–29°C), and indirect light.
Medium
Well-draining mix of peat, perlite, and sand; can also use cactus mix.
Hormone
Rooting hormone is recommended to improve success rate.
Timeline
Roots may appear in 4–6 weeks; new growth in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, humidity dome or plastic bag.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Selective thinning of branches; heading back to encourage branching.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased wood.
Tools
Pruning shears, sterilizing solution, gloves.
Checklist
Sterilize tools; prune dead/damaged wood; shape the plant; clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season starts.
Pot Size
Increase pot size by 2–3 inches in diameter; ensure good drainage.
Method
Remove plant gently; trim roots if necessary; place in a new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; necessary to refresh soil and provide space.
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 directly at the root zone, ensuring even saturation; water early in the morning to reduce evaporation; ensure excess water drains away.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves (cold stress); leaf drop or stunted growth (heat stress).
Cold Stress
Slows growth; may cause leaf drop; roots become susceptible to rot in cold, wet soil.
Solution: Move to a warmer location; protect from drafts; ensure soil is not waterlogged.
Hot Stress
Wilting; leaf scorch; reduced growth; may drop leaves to conserve water.
Solution: Provide shade during peak heat; 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.
