Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy or less vibrant in lower light.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight to avoid scorching; protect from harsh afternoon sun in very hot climates; place indoors near a south-facing window if grown as a houseplant.
Care Requirements
Care Difficulty
moderatemoderate
Sunlight
full sun
Rotate plant weekly for even growth; use sheer curtains to filter intense light indoors; avoid placing in shaded areas for prolonged periods.
Watering
every 2–3 weeks during active growth, less frequently in winter
Water thoroughly until it drains from the bottom; allow soil to dry out between waterings; adjust frequency based on season and weather.
Soil
well-drained, sandy loam
pH: Slightly acidic to neutral (pH 6.0–7.0).
Use a mix with good aeration; avoid heavy clay soils; ensure pots have drainage holes.
Temperature
Thrives in warm temperatures (65–85°F / 18–29°C); can tolerate brief periods of cooler temperatures but prefers stable warmth.
Protect from frost; ensure good air circulation; avoid sudden temperature fluctuations.
Fertilizing
every 2 months during growing season, none in winter
Apply fertilizer to moist soil to prevent root burn; flush soil occasionally to prevent salt buildup; reduce frequency in dormant periods.
Propagation
Methods
Stem cuttings or seed; stem cuttings are more common and reliable for home growers.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting.
- Remove lower leaves.
- Apply rooting hormone.
- Plant in moist propagation medium.
- Maintain humidity and warmth.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–80°F / 21–27°C), humid environment with bright, indirect light.
Medium
Well-draining mix of perlite and peat moss or cactus/succulent potting mix.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots typically develop in 4–8 weeks; new growth may appear in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, propagation tray, plastic wrap or humidity dome.
Quick Tips
Use healthy, non-flowering stems; keep soil consistently moist but not waterlogged; provide bottom heat if possible.
Pruning & Repotting
Pruning Guide
Method
Selective pruning of individual stems; pinch back tips to encourage branching.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or diseased wood; also prune after flowering to promote new blooms.
Tools
Pruning shears, loppers (for larger stems), gloves.
Checklist
Sterilize tools; prune during dormancy; remove dead/diseased wood; shape the plant; clean up debris.
Repotting Guide
Best Season
Early spring before the growing season begins.
Pot Size
Choose a pot one size larger (1–2 inches wider in diameter) than the current one.
Method
Remove plant gently; trim any circling roots; place in a new pot with fresh, well-draining soil; water thoroughly after repotting.
Suggestions
Repot every 2–3 years or when roots fill the container; necessary to refresh soil and provide more space for growth.
Checklist
Select appropriate pot size; prepare fresh soil mix; handle roots carefully; water after repotting; place in appropriate light.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; adjust frequency seasonally.
How to Apply Water Properly
Water directly at the root zone, ensuring even moisture distribution; water deeply to encourage root growth; ensure excess water drains away to prevent root rot; water early in the morning or late in the evening to minimize evaporation.
Watering Schedule Tips
Water deeply once every 7–10 days during active growth in spring and summer; reduce frequency to every 3–4 weeks in fall and winter, allowing soil to dry completely between waterings.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for organic matter; ensure soil is loose and aerated.
Temperature Stress Management
Signs of Temperature Issues
Chlorosis (yellowing leaves), leaf drop, stunted growth, or wilting in response to extreme cold or heat.
Cold Stress
Prolonged exposure to temperatures below 50°F (10°C) can cause leaf drop, root damage, and reduced vigor.
Solution: Move container plants indoors or to a sheltered location; provide frost protection in winter; avoid placing near drafty windows or doors.
Hot Stress
Excessive heat (above 90°F / 32°C) can lead to leaf scorch, wilting, and reduced flowering.
Solution: Provide shade during peak afternoon sun; increase watering frequency to compensate for evaporation; mist foliage lightly during extreme heat.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; dilute properly; fertilize during growing season only; avoid 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); avoid fertilizing in fall and winter.
