Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours/day); tolerates partial shade but may become leggy.
Sunlight Tolerance Tips:
Acclimate gradually if moving from shade to sun; protect from intense midday sun in hot climates; ensure good air circulation to prevent fungal issues.
Care Requirements
Care Difficulty
very easymoderate
Sunlight
full sun
Rotate plant weekly for even growth; use sheer curtains to filter harsh sun; avoid placing near large windows with direct afternoon sun.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure excellent drainage; avoid waterlogged soil.
Soil
well-drained, sandy or loamy soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a pot with drainage holes; avoid heavy clay soils; top-dress with compost annually.
Temperature
Prefers warm temperatures (65–85°F/18–29°C); can tolerate mild frosts but thrives in warmth.
Avoid sudden temperature changes; maintain consistent warmth; protect from cold drafts.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer to moist soil to prevent root burn; flush soil occasionally to prevent salt buildup; stop fertilizing if plant shows signs of stress.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in propagation medium.
- Keep moist and humid.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–90%), warm temperatures (70–75°F/21–24°C), and indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus mix.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots typically form in 2–4 weeks; new growth may take 1–2 months.
Tools Needed
Pruning shears, rooting hormone, propagation tray, humidity dome, well-draining medium.
Quick Tips
Use sterile tools to prevent disease; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth; cut just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased parts.
Tools
Pruning shears, sharp scissors, or a sharp knife.
Checklist
Use clean tools; prune dead or yellowing leaves; shape the plant evenly; avoid over-pruning.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Choose a pot one size larger (1–2 inches wider) than the current one.
Method
Remove plant gently; trim any circling roots; place in a new pot with fresh soil; water lightly after repotting.
Suggestions
Repot every 2–3 years or when roots outgrow the pot; beneficial for rejuvenation.
Checklist
Select appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil dryness; water deeply; ensure drainage; avoid overhead watering.
How to Apply Water Properly
Water directly at the root zone until water drains from the bottom; avoid wetting foliage; water in the morning to allow foliage to dry.
Watering Schedule Tips
Water sparingly, allowing soil to dry completely between waterings; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in cold; scorching or leaf drop in excessive heat.
Cold Stress
Slows growth, may cause root damage, and increases susceptibility to disease.
Solution: Move to a warmer location; use a heat mat if necessary; avoid cold drafts.
Hot Stress
Leaves may scorch, growth may slow, and water needs increase.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; apply during growing season; avoid winter feeding; flush soil periodically.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; fertilize monthly during growing season (spring/summer); avoid fertilizing in winter.
