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:
Gradually acclimate to direct sun to prevent scorching; place in a spot with filtered light if outdoors; rotate the plant for even growth.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun to partial shade
Avoid intense afternoon sun; rotate plant weekly; use sheer curtains for filtered light.
Watering
every 7–10 days during active growth, reduce to every 3–4 weeks in winter
Allow soil to dry between waterings; water deeply but infrequently; avoid overwatering.
Soil
well-draining, sandy or gritty potting mix
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure soil dries between waterings; use a mix designed for succulents; avoid heavy clay soils.
Temperature
Prefers 60–75°F (15–24°C); tolerates mild frost but thrives in moderate temperatures.
Protect from frost; avoid drafts; maintain moderate temperatures.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer, none in winter
Dilute fertilizer to prevent burn; fertilize only during active growth; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or leaf cuttings.
Step-by-Step Propagation Guide
- Take a cutting.
- Let it callus for a few days.
- Plant in moist medium.
- Keep warm and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light.
Medium
Well-draining mix like cactus soil with perlite or sand.
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, small pots, well-draining soil.
Quick Tips
Let cuttings callus before planting; use bottom heat for faster rooting; keep soil lightly moist.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a leaf node or junction; use clean, sharp tools.
Pruning Plan
Remove dead or leggy stems to encourage bushier growth and maintain shape.
Tools
Pruning shears, sterilized knife.
Checklist
Sterilize tools; cut dead/leggy stems; dispose of clippings; monitor for new growth.
Repotting Guide
Best Season
Spring, before the growing season begins.
Pot Size
One size up from current pot; ensure good drainage.
Method
Remove plant gently; trim roots if necessary; place in a slightly larger pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; use fresh, well-draining soil.
Checklist
Choose appropriate pot; prepare fresh soil; handle roots carefully; 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 soil level, ensuring even moisture without saturating the plant; allow excess water to drain completely; 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.
Soil Improvement
Add perlite, sand, or pumice to improve drainage; use a mix with organic matter for nutrients.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or stunted growth in extreme heat or cold; yellowing leaves in cold stress.
Cold Stress
Slows growth and can cause root rot due to reduced water uptake in cold, damp conditions.
Solution: Move to a warmer location; reduce watering; use a heat mat if necessary.
Hot Stress
Leaves may wilt or curl; growth may slow due to excessive water loss.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid overwatering.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize in spring/summer; avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring and summer); avoid fertilizing in winter.
