Care Details
Ideal Sunlight Coverage:
Bright indirect light for 6–8 hours daily; can tolerate direct morning sun but avoid harsh afternoon sun.
Sunlight Tolerance Tips:
Acclimate gradually to direct light; protect from intense midday sun; place in a spot with filtered light if outdoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter intense light; avoid sudden light changes.
Watering
every 7–10 days during active growth, reduce in winter
Allow soil to dry between waterings; avoid overwatering; water less in dormant periods.
Soil
well-draining, sandy or rocky soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy garden soil; topdress with gravel for extra drainage.
Temperature
Prefers 65–80°F (18–27°C); tolerates mild frost but thrives in warm conditions; avoid temperatures below 50°F (10°C).
Avoid sudden temperature changes; protect from cold drafts; maintain consistent warmth during active growth.
Fertilizing
every 4–6 weeks during growing season, none in winter
Dilute fertilizer to prevent burn; fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings; leaf cuttings can also work but are slower.
Step-by-Step Propagation Guide
- Take a healthy cutting.
- Let it callus for a few days.
- Plant in moist medium.
- Keep humid and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain 70–80°F (21–27°C).
Medium
Well-draining mix of perlite and peat moss or cactus soil.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots in 2–4 weeks; new growth in 1–2 months.
Tools Needed
Sharp knife, rooting hormone (optional), small pots, well-draining medium.
Quick Tips
Allow cuttings to callus before planting; maintain humidity with a plastic bag; use sterile tools to prevent rot.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a leaf node or junction; avoid cutting into old wood.
Pruning Plan
Remove dead or leggy stems to encourage bushier growth; prune after flowering to maintain shape.
Tools
Sharp, clean pruning shears, gloves (sap can be irritating).
Checklist
Sterilize tools; prune after flowering; remove dead or damaged stems; wear gloves.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Move to a pot 1–2 inches larger in diameter; ensure it has drainage holes.
Method
Remove plant gently; trim roots if necessary; repot in fresh, well-draining soil; ensure good drainage.
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 lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; adjust seasonally.
How to Apply Water Properly
Water deeply at the root zone until water drains from the bottom; ensure excess water drains away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water thoroughly when the top inch of soil is dry; reduce frequency in winter to prevent root rot; adjust based on humidity and temperature.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate organic matter for fertility.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves (cold stress); wilting or leaf drop (heat stress); stunted growth.
Cold Stress
Slows growth; may cause leaf drop; can lead to root rot if soil remains cold and wet.
Solution: Move to a warmer location; protect from drafts; reduce watering in cold conditions.
Hot Stress
Leaf scorch; wilting; reduced flowering; 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; avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
