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 summer; ensure good air circulation to prevent mildew.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant weekly for even growth; use sheer curtains to filter harsh sun; avoid placing near reflective surfaces that intensify light.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overhead watering to prevent fungal issues.
Soil
well-draining, sandy loam with some organic matter
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 60–75°F (15–24°C); can tolerate brief dips to 50°F (10°C) but thrives in warmth.
Avoid drafty areas; maintain consistent room temperature; use a thermometer to monitor extremes.
Fertilizing
every 4–6 weeks during growing season, none in winter
Fertilize after watering to prevent root burn; flush soil occasionally to remove salt buildup; avoid over-fertilizing.
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 medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (65–75°F), and indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus soil.
Hormone
Recommended to use rooting hormone for faster root development.
Timeline
Roots develop in 3–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, misting bottle, plastic wrap.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Cut stems just above a leaf node or bud; remove crossing or crowded branches to improve air circulation.
Pruning Plan
Remove dead or overgrown stems to maintain shape and encourage bushier growth; prune after flowering to promote new blooms.
Tools
Pruning shears, sterilizing solution, gloves.
Checklist
Sterilize tools; prune during dormancy or after flowering; remove dead/damaged growth; shape as desired.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Choose a pot 1–2 inches larger in diameter 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 fill the pot; necessary to refresh soil and provide space for growth.
Checklist
Select appropriate pot; prepare new soil mix; water plant a day before repotting; handle roots carefully.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water deeply; ensure drainage; avoid wetting leaves.
How to Apply Water Properly
Water at the base of the plant, ensuring moisture reaches the root zone; allow excess water to drain freely; water in the morning to reduce evaporation and fungal risk.
Watering Schedule Tips
Water deeply once the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility; use a cactus or succulent mix as a base.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, or stunted growth in cold; leaf scorch or drop in excessive heat.
Cold Stress
Slows growth, weakens defenses, and may cause root damage in prolonged cold.
Solution: Move to a warmer location; use a space heater if needed; insulate pots with bubble wrap in winter.
Hot Stress
Leaves may scorch, wilt, or drop; soil dries out rapidly, stressing roots.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute correctly; apply during active growth; stop in dormant season.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); cease in fall/winter.
