Care Details
Ideal Sunlight Coverage:
Bright indirect light or full sun for 6–8 hours daily; adjust for intense summer sun.
Sunlight Tolerance Tips:
Acclimate gradually to intense light; protect from harsh midday sun; provide shade during peak summer.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun to partial shade
Morning sun is ideal; rotate plant for even growth; avoid direct afternoon sun in summer.
Watering
every 7–10 days during active growth, reduce in winter
Water deeply but infrequently; ensure good drainage; avoid waterlogged soil.
Soil
well-draining, fertile soil with some organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure pots have drainage holes; avoid heavy clay soils; topdress with compost annually.
Temperature
Prefers 60–85°F (15–29°C); tolerates mild frosts but thrives in warm conditions.
Protect from frost; avoid sudden temperature swings; maintain moderate warmth for best growth.
Fertilizing
every 4–6 weeks during spring and summer
Fertilize after watering to prevent root burn; stop in fall/winter; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings with at least two nodes.
Step-by-Step Propagation Guide
- Take cutting.
- Apply hormone.
- Plant in medium.
- Cover with plastic.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
High humidity (70–80%), warm temperatures (70–75°F), and indirect light.
Medium
Well-draining mix of peat, perlite, and sand.
Hormone
Rooting hormone is recommended for faster rooting.
Timeline
Roots in 4–8 weeks; establish in 3–6 months.
Tools Needed
Pruners, rooting hormone, plastic bag, misting bottle.
Quick Tips
Use healthy, non-flowering stems; keep consistently moist; provide bottom heat for faster rooting.
Pruning & Repotting
Pruning Guide
Method
Cut back stems to a healthy bud or lateral branch; remove crossing or crowded growth.
Pruning Plan
Prune to control size, encourage bushier growth, and remove dead or overgrown stems.
Tools
Pruning shears, loppers, gloves.
Checklist
Disinfect tools; prune at the right time; make clean cuts; remove debris.
Repotting Guide
Best Season
Early spring before new growth begins.
Pot Size
Increase pot size by 2–3 inches in diameter.
Method
Remove plant gently; trim roots if needed; 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 flowering.
Checklist
Check root bound status; prepare new pot; use fresh soil; 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 thoroughly when the top inch of soil is dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, leaf drop, or stunted growth in extreme cold or heat.
Cold Stress
Slows growth, causes leaf drop, and may lead to frost damage in prolonged cold.
Solution: Move to a warmer location; provide frost protection; reduce watering in cold.
Hot Stress
Wilting, leaf scorch, or reduced flowering in excessive heat.
Solution: Provide shade; increase humidity; water early in the day; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Check season; 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); avoid fertilizing in winter.
