Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter intense light; avoid direct afternoon sun.
Watering
every 7–10 days, allowing soil to dry slightly between waterings
Water thoroughly but allow soil to dry between waterings; avoid overwatering.
Soil
moist, well-drained, loamy soil with organic matter
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure good drainage; amend with organic matter; avoid compacted soil.
Temperature
Prefers cool to moderate temperatures (60–75°F or 15–24°C); tolerates cooler nights.
Avoid sudden temperature changes; protect from frost; ensure good air circulation.
Fertilizing
every 4–6 weeks during growing season (spring to early fall)
Apply fertilizer after watering; flush soil occasionally to prevent salt buildup; stop fertilizing in dormant periods.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common for home growers.
Step-by-Step Propagation Guide
- Take 4–6 inch cuttings.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in medium.
- Keep moist and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain consistent moisture.
Medium
Well-draining potting mix with perlite or sand; can also root in water.
Hormone
Optional but recommended for faster rooting.
Timeline
Roots develop in 2–4 weeks; new growth appears in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining mix.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity; avoid direct sun during rooting.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips or cut stems just above a leaf node; remove dead or diseased parts.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or weak growth.
Tools
Clean pruning shears or scissors.
Checklist
Sterilize tools; prune dead/damaged growth; shape as desired; clean up debris.
Repotting Guide
Best Season
Spring, before new growth begins.
Pot Size
Choose a pot 1–2 inches larger in diameter than the current one.
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 health.
Checklist
Select appropriate pot; prepare new soil mix; handle roots carefully; water after repotting.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; adjust for season.
How to Apply Water Properly
Water at the base of the plant, ensuring even moisture distribution without saturating the soil; water early in the day to allow foliage to dry.
Watering Schedule Tips
Water when the top inch of soil is dry; reduce frequency 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, leaf drop, or stunted growth in extreme heat or cold; yellowing leaves in excessive heat.
Cold Stress
Slows growth; may cause leaf discoloration or dieback in prolonged cold.
Solution: Provide winter protection; move indoors if temperatures drop below 50°F (10°C); avoid cold drafts.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow in excessive heat.
Solution: Provide shade during peak heat; increase humidity; water more frequently but avoid waterlogging.
Fertilizing Guide
Fertilizing Checklist
Use diluted fertilizer; fertilize during active growth; avoid winter feeding.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring to early fall); avoid fertilizing in winter.
