Care Requirements
Care Difficulty
easyeasy
Sunlight
partial shade to full sun
Avoid intense afternoon sun; rotate plant for even growth; provide shade during peak heat.
Watering
every 3–5 days, more frequently in hot weather
Water thoroughly when top inch of soil feels dry; ensure good drainage to avoid waterlogging.
Soil
moist, fertile, loamy soil with good organic content
pH: Slightly acidic to neutral, 6.0–7.0.
Ensure soil doesn’t compact; avoid heavy clay mixes; maintain consistent moisture.
Temperature
Thrives in warm conditions, 65–85°F (18–29°C); sensitive to frost.
Avoid drafts; maintain stable temperatures; protect from sudden temperature drops.
Fertilizing
every 4–6 weeks during growing season
Fertilize after watering to prevent root burn; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or division; stem cuttings root easily in water or moist soil.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Place in water or soil.
- Keep moist.
Best Time: Spring or early summer when plant is actively growing.
Environment
Warm, humid environment with indirect light.
Medium
Well-draining soil mix or water; can also use perlite or sand for faster rooting.
Hormone
Not necessary but can speed up rooting.
Timeline
Roots develop in 1–2 weeks in water; 3–4 weeks in soil.
Tools Needed
Sharp scissors, rooting hormone (optional), small pots or jars.
Quick Tips
Use healthy, non-flowering stems; change water every few days if using water propagation.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or leggy growth.
Tools
Sharp, clean scissors or pruning shears.
Checklist
Sterilize tools; prune dead or damaged growth; shape as desired.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
One size up; increase pot diameter by 2–3 inches.
Method
Use well-draining soil; gently tease out roots; place in slightly larger pot with drainage holes.
Suggestions
Repot every 1–2 years or when roots fill the pot; benefits from fresh soil and space.
Checklist
Choose appropriate pot; prepare fresh soil mix; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture daily; water thoroughly; ensure drainage; adjust for season.
How to Apply Water Properly
Water evenly at the base, avoiding foliage; ensure water penetrates root zone and drains freely; water in the morning to reduce evaporation.
Watering Schedule Tips
Keep soil consistently moist, especially during active growth; reduce watering in winter to prevent root rot.
Soil Improvement
Add compost or peat moss for fertility; mix in perlite or sand for drainage.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or leaf drop in extreme heat or cold.
Cold Stress
Growth halts below 50°F (10°C); prolonged cold can cause root damage or death.
Solution: Protect from frost; move indoors in winter; use a heat mat for propagation in cold climates.
Hot Stress
Leaves may scorch or wilt in excessive heat; growth slows if not hydrated.
Solution: Provide shade during peak heat; increase humidity; water more frequently in hot weather.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during active growth; avoid winter feeding.
Fertilizing Method
Use balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season; avoid fertilizing in winter.
