Full sun (6–8 hours/day); tolerates coastal exposure; adjust for intense summer heat.
Sunlight Tolerance Tips:
Acclimate gradually to intense sunlight; protect from harsh midday sun in summer; suitable for coastal or sandy environments.
Care Requirements
Care Difficulty
easyeasy
Sunlight
full sun
Full sun lover; coastal tolerant; avoid deep shade.
Watering
every 2–3 days, or when soil surface is dry
Keep soil evenly moist; avoid waterlogging; adjust frequency based on weather and growth stage.
Soil
sandy, saline, or alkaline soil
pH: Slightly acidic to neutral (pH 6.0–7.0).
Ensure excellent drainage; use sandy mix; avoid waterlogged conditions.
Temperature
Thrives in moderate to warm temperatures (15–30°C); tolerates coastal conditions; sensitive to prolonged frost.
Protect from frost; water more in heat; coastal tolerance is high.
Fertilizing
rarely required, every 3 months if grown in poor soil
Use diluted fertilizer; fertilize in spring/summer only; avoid high-nitrogen formulas.
Propagation
Methods
Seed or stem cuttings; easily propagated from seed in spring.
Step-by-Step Propagation Guide
- Prepare medium.
- Sow seeds or take cuttings.
- Keep moist.
- Provide warmth and light.
Best Time: Spring or early summer for best success.
Environment
Warm, bright, and humid conditions; protect from strong winds.
Medium
Well-draining sandy soil or seed-starting mix.
Hormone
Not typically required for seeds; optional for cuttings.
Timeline
Seeds germinate in 2–4 weeks; cuttings root in 3–6 weeks.
Tools Needed
Seed trays, pruners, misting bottle, heating mat (optional).
Quick Tips
Use fresh seeds for best germination; keep cuttings humid; avoid overwatering.
Pruning & Repotting
Pruning Guide
Method
Snip back dead stems; thin overcrowded areas; shape lightly if desired.
Pruning Plan
Minimal pruning needed; remove dead or damaged growth to maintain vigor.
Tools
Pruning shears, gloves, clean blades.
Checklist
Disinfect tools; prune dead growth; avoid over-pruning.
Repotting Guide
Best Season
Spring, before active growth begins.
Pot Size
One size up; avoid excessive pot size increase.
Method
Use fresh, well-draining soil; gently tease out roots; ensure good drainage.
Suggestions
Repot only when root-bound or soil degrades; typically every 2–3 years.
Checklist
Check root health; use fresh soil; ensure drainage holes are clear.
Advanced Care Tips
Watering Mastery
Watering Checklist
Check soil moisture daily; water deeply; ensure proper drainage; adjust for season.
How to Apply Water Properly
Water thoroughly at the root zone until water drains from the bottom; allow topsoil to dry slightly between waterings; water early in the day to minimize evaporation.
Watering Schedule Tips
Water frequently, especially in dry conditions; maintain consistently moist soil; reduce watering in winter dormancy.
Soil Improvement
Add sand or perlite for drainage; incorporate compost for fertility; avoid heavy clay soils.
Temperature Stress Management
Signs of Temperature Issues
Wilting, leaf drop, or chlorosis in extreme heat; stunted growth or browning in cold stress.
Cold Stress
Growth slows or halts; may suffer tissue damage in freezing temperatures; less tolerant of cold than heat.
Solution: Provide frost protection in winter; avoid overwatering in cold; move to a sheltered location if possible.
Hot Stress
Leaves may wilt or scorch; growth may slow; requires consistent moisture in high heat.
Solution: Increase watering frequency; provide partial shade during peak heat; ensure good air circulation.
Fertilizing Guide
Fertilizing Checklist
Use balanced fertilizer; dilute to half strength; apply during active growth.
Fertilizing Method
Light feeding with balanced, low-nitrogen fertilizer; apply monthly during growing season; avoid over-fertilization.
