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 light; 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 for even light exposure; use sheer curtains to filter intense light; avoid drafty windows.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering.
Soil
well-draining, sandy loam with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use pots with drainage holes; avoid compacted soil; topdress with mulch to retain moisture.
Temperature
Prefers 65–80°F (18–27°C); tolerates mild fluctuations but avoid prolonged exposure to extremes.
Avoid sudden temperature changes; protect from drafts; maintain consistent room temperature.
Fertilizing
every 4–6 weeks during spring and summer, none in winter
Dilute fertilizer to prevent burn; fertilize only when actively growing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings; semi-hardwood cuttings root most reliably.
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 (70–90%), warm temperatures (70–75°F/21–24°C), and indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus mix.
Hormone
Recommended to use rooting hormone for faster and more reliable rooting.
Timeline
Roots typically form in 4–8 weeks; new growth may take 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, plastic bags or propagation dome, misting bottle.
Quick Tips
Use clean tools to prevent disease; maintain consistent moisture; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth; trim leggy stems to encourage branching.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or leggy growth.
Tools
Pruning shears, sharp scissors, disinfectant.
Checklist
Sanitize tools; prune during active growth; remove dead/damaged growth; shape as desired.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Increase pot size by 1–2 inches in diameter; ensure good drainage.
Method
Remove plant gently; trim roots if necessary; place in new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots fill the pot; beneficial for growth and soil health.
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 at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain away; water in the morning to reduce evaporation.
Watering Schedule Tips
Water deeply when the top 1–2 inches of soil are dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or stunted growth; yellowing leaves in cold; scorching in excessive heat.
Cold Stress
Slows growth; may cause root damage or leaf drop; increases susceptibility to pests.
Solution: Move to a warmer location; insulate pots; avoid cold drafts; reduce watering in cold periods.
Hot Stress
Leaf scorch, wilting, or dehydration; may drop leaves to conserve water.
Solution: Provide shade; increase humidity; water more frequently but avoid waterlogging; use shade cloth outdoors.
Fertilizing Guide
Fertilizing Checklist
Check growth phase; dilute fertilizer; apply to moist soil; avoid contact with roots.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
