Care Details
Ideal Sunlight Coverage:
Full sun (6–8 hours of direct sunlight daily); tolerates partial shade but may become leggy with insufficient light.
Sunlight Tolerance Tips:
Acclimate plants gradually to intense sunlight to prevent scorching; place in a location with unobstructed sun exposure; for indoor cultivation, use a south-facing window.
Care Requirements
Care Difficulty
easymoderate
Sunlight
full sun to partial shade
Rotate plant weekly for even growth; use sheer curtains to filter harsh midday sun; supplement with grow lights if indoors.
Watering
every 7–10 days during active growth, less frequently in winter
Water thoroughly but infrequently; ensure soil dries between waterings; avoid overwatering to prevent root rot.
Soil
well-draining, sandy or loamy soil
pH: Slightly alkaline to neutral (pH 6.5–7.5).
Ensure pots have drainage holes; avoid heavy clay soils; test soil pH periodically.
Temperature
Prefers moderate temperatures (60–75°F or 15–24°C); can tolerate cooler temperatures down to 40°F (4°C) but avoid frost.
Avoid placing near drafty windows or heating vents; maintain consistent temperatures; protect from frost.
Fertilizing
every 4–6 weeks during spring and summer, none in fall and winter
Fertilize only when actively growing; flush soil occasionally to prevent salt buildup; use a low-nitrogen formula for flowering plants.
Propagation
Methods
Stem cuttings; division of clumps for mature plants.
Step-by-Step Propagation Guide
- Take a 4–6 inch cutting with at least two nodes.
- Remove lower leaves.
- Dip in rooting hormone.
- Plant in moist medium.
- Maintain humidity.
Best Time: Spring or early summer when the plant is actively growing.
Environment
Warm (70–75°F or 21–24°C), humid environment with indirect light; protect from direct sun.
Medium
Well-draining potting mix with perlite or sand; can also root in water initially.
Hormone
Rooting hormone is recommended to improve success rates.
Timeline
Roots typically form in 3–6 weeks; new growth may appear in 2–3 months.
Tools Needed
Pruning shears, rooting hormone, small pots, well-draining soil mix, plastic wrap or propagator.
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 thinning of stems; heading back to encourage branching; remove dead or crossing branches.
Pruning Plan
Prune to maintain shape, encourage bushier growth, and remove dead or damaged stems; best done after flowering or in early spring.
Tools
Pruning shears, loppers (for thicker stems), gloves, disinfectant for tools.
Checklist
Disinfect tools before use; prune during dry weather; make clean cuts just above a node or bud; remove debris after pruning.
Repotting Guide
Best Season
Early spring before new growth 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 space for growth.
Checklist
Select appropriate pot size; prepare fresh soil mix; handle roots carefully; water and place in a shaded area for a few days.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture before watering; water deeply; ensure proper drainage; avoid overhead watering.
How to Apply Water Properly
Water at the base of the plant, targeting the root zone; apply until water drains from the bottom; avoid wetting foliage to reduce fungal risk; water early in the day 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. Adjust based on rainfall and soil dryness.
Soil Improvement
Add perlite or coarse sand to improve drainage; incorporate compost for fertility; use mulch to retain moisture and suppress weeds.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or browning leaf edges in excessive heat; stunted growth or yellowing leaves in cold stress.
Cold Stress
Low temperatures slow growth and may cause leaf damage or dieback; prolonged exposure to freezing temperatures can be fatal.
Solution: Move potted plants indoors or to a sheltered location during cold spells; apply a layer of mulch to insulate roots in-ground plants.
Hot Stress
Excessive heat can lead to dehydration, leaf scorch, or reduced flowering; may cause the plant to go dormant.
Solution: Provide shade during peak heat; increase watering frequency; use mulch to retain soil moisture.
Fertilizing Guide
Fertilizing Checklist
Check growth phase before fertilizing; dilute fertilizer correctly; apply to moist soil; avoid contact with foliage.
Fertilizing Method
Use a balanced, water-soluble fertilizer diluted to half strength; apply every 4–6 weeks during spring and summer; avoid fertilizing in fall and winter.
