Care Details
Ideal Sunlight Coverage:
Full sun to partial shade; 6–8 hours of direct sunlight daily, with some afternoon shade in hot climates.
Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight; protect from harsh midday sun; adjust placement based on seasonal light changes.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
partial shade to full sun
Use shade cloth in intense sun; rotate plant for even light exposure; monitor for sunburn.
Watering
every 7–10 days during active growth, reduce in winter
Water thoroughly until it drains from the bottom; allow soil to dry between waterings; avoid overwatering.
Soil
well-draining, loamy soil 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
Thrives in warm temperatures, 20–30°C (68–86°F); tolerates brief periods of cooler temperatures but prefers stable warmth.
Protect from frost; avoid sudden temperature swings; maintain consistent warmth.
Fertilizing
every 4–6 weeks during growing season with balanced liquid fertilizer
Apply fertilizer after watering to prevent root burn; avoid over-fertilizing; flush soil occasionally to prevent salt buildup.
Propagation
Methods
Stem cuttings or seeds; stem cuttings are more common and reliable for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in moist medium.
- Keep humid and warm.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm, humid environment with indirect light; maintain temperatures around 24–27°C (75–80°F).
Medium
Well-draining potting mix, such as a mix of peat, perlite, and sand.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots typically develop in 4–8 weeks; new growth may take an additional 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, misting spray bottle, plastic wrap.
Quick Tips
Use healthy, non-flowering stems; maintain high humidity; avoid direct sunlight during rooting.
Pruning & Repotting
Pruning Guide
Method
Selective pruning of branches to shape the plant; cut just above a leaf node or bud.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased branches.
Tools
Pruning shears, loppers, gloves, disinfectant.
Checklist
Disinfect tools; prune dead/damaged branches first; shape the plant; clean up debris.
Repotting Guide
Best Season
Spring, before the active growing season begins.
Pot Size
Choose a pot one size larger (about 2–5 cm wider in diameter) than the current one.
Method
Remove plant gently; trim any circling roots; place in a new pot with fresh soil; water lightly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the pot; necessary to refresh soil and provide space for growth.
Checklist
Select appropriate pot; prepare new soil mix; handle roots carefully; water after repotting; place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture; water thoroughly; ensure drainage; adjust for season.
How to Apply Water Properly
Water directly at the root zone, ensuring even saturation; water early in the morning to minimize evaporation; ensure excess water drains away to prevent waterlogging.
Watering Schedule Tips
Water deeply once the top inch of soil feels dry; reduce frequency in winter to prevent root rot.
Soil Improvement
Add perlite or coarse sand for drainage; incorporate compost for fertility; ensure good aeration.
Temperature Stress Management
Signs of Temperature Issues
Yellowing leaves, leaf drop, stunted growth, or wilting in extreme heat or cold.
Cold Stress
Slows growth, causes leaf drop, and may lead to root damage if temperatures drop below 10°C (50°F).
Solution: Move to a warmer location; provide frost protection; avoid watering during cold spells.
Hot Stress
Wilting, leaf scorch, and reduced flowering due to excessive heat and dry conditions.
Solution: Provide shade during peak heat; increase humidity; water deeply and more frequently.
Fertilizing Guide
Fertilizing Checklist
Check fertilizer type; dilute correctly; apply during growing season; monitor for signs of over-fertilization.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength every 4–6 weeks during the growing season (spring and summer); reduce or stop in fall and winter.
