Full sun to partial shade (6–8 hours of direct sunlight daily); tolerates some shade in hot climates.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight; protect from harsh afternoon sun in hot regions; adjust placement based on seasonal light changes.
Care Requirements
Care Difficulty
very easymoderate
Sunlight
full sun to partial shade
Rotate plant for even growth; use shade cloth in extreme heat; avoid direct sun during peak hours.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering.
Soil
well-draining, sandy loam with moderate organic content
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
Prefers moderate temperatures (60–75°F or 15–24°C); can tolerate cooler conditions but avoid frost.
Avoid drafts; maintain consistent temperatures; protect from extreme fluctuations.
Fertilizing
every 4–6 weeks during growing season, none in winter
Apply fertilizer after watering; flush soil occasionally to prevent salt buildup; stop fertilizing in fall.
Propagation
Methods
Stem cuttings or division; stem cuttings are the most common method.
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, such as a mix of peat, perlite, and sand.
Hormone
Rooting hormone is optional but can improve success rates.
Timeline
Roots typically develop in 2–4 weeks; new growth may appear in 6–8 weeks.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining soil mix.
Quick Tips
Use clean tools; maintain humidity with a plastic bag; avoid overwatering.
Pruning & Repotting
Pruning Guide
Method
Pinch back stems or use clean cuts to encourage branching.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased parts.
Tools
Pruning shears, sterilized knife, gloves.
Checklist
Sterilize tools; prune dead/damaged parts; shape the plant; clean up debris.
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 roots if necessary; place in a new pot with fresh soil; water lightly.
Suggestions
Repot every 2–3 years or when roots outgrow the container; beneficial for growth and health.
Checklist
Prepare new pot; trim roots; add fresh soil; water; place in appropriate light.
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 deeply when the top 1–2 inches of soil are dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or sand for drainage; incorporate compost for fertility; ensure good aeration.
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, and can lead to frost damage if temperatures drop below freezing.
Solution: Move to a sheltered location; provide frost protection; avoid sudden temperature drops.
Hot Stress
Leaves may scorch, wilt, or drop; growth may slow due to excessive heat.
Solution: Provide shade during peak heat; increase watering; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check season; dilute fertilizer; apply to moist soil; avoid contact with foliage.
Fertilizing Method
Use a balanced liquid fertilizer diluted to half strength every 4–6 weeks during the growing season (spring and summer); avoid fertilizing in winter.
