Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight; protect from harsh midday sun in hot climates; place in the brightest location indoors.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant weekly for even growth; provide shade during extreme heat; avoid sudden light changes.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries out fully between waterings; avoid overwatering to prevent root rot.
Soil
well-draining, sandy or loamy soil with low organic content
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 warm temperatures (65–85°F / 18–29°C); can tolerate mild frost but thrives in heat.
Avoid sudden temperature changes; protect from frost; maintain consistent warmth during active growth.
Fertilizing
every 4–6 weeks during growing season, none in winter
Fertilize only during active growth; dilute fertilizer to prevent burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings; division of offsets.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Let it callus for a few days.
- Plant in moist propagation medium.
- Keep warm and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F / 21–24°C), humid, and bright but indirect light.
Medium
Well-draining mix of perlite and cactus/succulent soil.
Hormone
Rooting hormone is optional but recommended for faster rooting.
Timeline
Roots develop in 3–6 weeks; new growth appears in 2–4 months.
Tools Needed
Sharp knife or scissors, rooting hormone, small pots, propagation medium.
Quick Tips
Allow cuttings to callus before planting; maintain humidity with a plastic cover; use sterile tools.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushiness; cut stems just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or overgrown stems.
Tools
Clean, sharp pruning shears or scissors.
Checklist
Sterilize tools; prune during active growth; remove dead or diseased parts.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter).
Method
Remove plant gently; trim roots if necessary; repot in fresh, well-draining soil with a slightly larger pot.
Suggestions
Repot every 2–3 years or when roots fill the pot; necessary to refresh soil and provide space.
Checklist
Use fresh soil; ensure good drainage; handle roots carefully; water lightly after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency by season.
How to Apply Water Properly
Water directly at the root zone until water drains from the bottom; ensure even moisture without waterlogging; water in the morning to allow foliage to dry.
Watering Schedule Tips
Water deeply once every 7–10 days during active growth in spring and summer; reduce frequency to every 3–4 weeks in fall and winter, allowing soil to dry completely between waterings.
Soil Improvement
Add perlite, coarse sand, or pumice to improve drainage; incorporate compost 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 or yellowing; vulnerable to root rot in cold, wet soil.
Solution: Move to a warmer location; protect from drafts; reduce watering in cool conditions.
Hot Stress
Leaves may wilt or scorch; growth may slow; soil may dry out too quickly.
Solution: Provide shade during peak heat; increase watering frequency; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during growing season; avoid winter feeding.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during spring and summer; avoid fertilizing in fall and winter.
