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 hot climates; ensure good air circulation to prevent fungal issues.
Care Requirements
Care Difficulty
very easyeasy
Sunlight
full sun to partial shade
Rotate plant for even growth; use sheer curtains to filter harsh sunlight; avoid placing near large windows with direct afternoon sun.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure proper drainage; avoid wetting foliage.
Soil
well-draining, sandy loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix of potting soil and perlite; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Warm conditions (65–85°F/18–29°C); tolerates mild frosts but prefers stable warmth.
Avoid drafts; maintain stable temperatures; protect from sudden temperature swings.
Fertilizing
every 4–6 weeks during growing season
Apply fertilizer after watering to prevent root burn; flush soil occasionally to prevent salt buildup; stop fertilizing if plant shows signs of over-fertilization.
Propagation
Methods
Stem cuttings or division; stem cuttings are more common and reliable.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone (optional).
- Plant in moist medium.
- Keep warm and humid.
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 (e.g., perlite and peat moss mix) or water propagation.
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 medium.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity with a plastic bag; avoid direct sunlight.
Pruning & Repotting
Pruning Guide
Method
Pinch back tips for bushier growth; cut stems just above a leaf node.
Pruning Plan
Prune to maintain shape, encourage bushiness, and remove dead or overgrown stems.
Tools
Pruning shears, sharp knife, gloves.
Checklist
Sterilize tools; prune in early morning; remove dead/damaged growth; shape as desired.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
One size larger pot (e.g., +2 inches in diameter).
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 health.
Checklist
Choose appropriate pot size; use fresh soil mix; ensure good drainage; water after repotting.
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 away; water early in the morning to minimize evaporation.
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 sand for drainage; incorporate compost for fertility; ensure soil is loose and airy.
Temperature Stress Management
Signs of Temperature Issues
Wilting, yellowing leaves, stunted growth, or bud drop in extreme heat or cold.
Cold Stress
Slows growth, may cause leaf drop or dieback in prolonged cold; susceptible to frost damage.
Solution: Move to a warmer location; provide frost protection in cold climates; avoid sudden temperature drops.
Hot Stress
Leaf scorch, wilting, or reduced flowering in excessive heat; may drop leaves to conserve water.
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 balanced liquid fertilizer diluted to half strength every 4–6 weeks during growing season (spring/summer); avoid fertilizing in winter.
