In a context of climate change and increasing water stress, xeriscaping has emerged as the smart solution for creating beautiful and sustainable green spaces. By 2025, this technique, which reduces water consumption by up to 80% compared to traditional gardens, is gaining global popularity, proving that it is possible to have lush vegetation without wasting water resources.
What is Xeriscaping?
Xeriscaping (from the Greek xeros, meaning dry) is a system of garden design and maintenance that:
- Minimizes water use through adapted plants and efficient techniques
- Maximizes local biodiversity
- Reduces maintenance and associated costs
- Integrates ecological principles into every element of the design
Key fact: A xeriscaping garden consumes only 2-3 liters/m²/day compared to 12-15 liters for a conventional garden.
The 7 Principles of Xeriscaping
1. Intelligent Planning and Design
- Microclimatic Analysis: Identify sun/shade zones, wind, and runoff areas
- Hydrizontal Sectors: Group plants by water needs
- Zoning:
- Zone 0 (close to home): More ornamental species and some irrigation
- Zone 1 (medium distance): Mediterranean plants with drip irrigation
- Zone 2 (periphery): Native dryland species, no irrigation
2. Soil Improvement
- Organic Matter: Compost and worm castings (increase water retention by 40%)
- Mulching:
- Organic: Pine bark, straw, pruning remains (5-10 cm thick)
- Mineral: Gravel, slate, pebbles (especially for succulents)
- Advantages of Mulching:
- Reduces evaporation 70%
- Controls weeds
- Regulates soil temperature
3. Appropriate Plant Selection
- Selection criteria:
- Native plants: Adapted to the local climate
- Xerophytes: Specialized in surviving with little water
- Mediterranean plants: Rosemary, lavender, thyme, rockrose
- Succulents and succulents: Aloes, everlastings, sedum
4. Practical Turf Areas
- Minimize: Only where truly useful
- Turf alternatives:
- Dwarf clover: Drought-resistant, nitrogen-fixing
- Dichondra: Low-maintenance groundcover
- Zoysia japonica: Deep-rhizomed turf
5. High-Efficiency Irrigation
- Recommended systems:
- Subsurface drip: 95% efficient vs. 65% efficient sprinkler
- Exudation tapes: For hedges and borders
- Smart scheduling:
- Irrigation Night or dawn
- Humidity and rain sensors
6. Use of Ground Covers
- Functions:
- Protect the soil from direct sunlight
- Reduce erosion
- Create microhabitats
- Ground cover species:
- Lippia nodiflora: Resistant to light trampling
- Lampranthus: Spectacular flowering
7. Proper Maintenance
- Strategic pruning: Promotes compact growth
- Organic fertilization: Improves plant resilience
- Weed control: Prevents competition for water
Star Species for Xeriscaping in 2025
Trees and Shrubs
- Olive (Olea europaea): Mediterranean icon, zero maintenance
- Mastic (Pistacia lentiscus): Evergreen, very resistant
- Creeping rosemary (Rosmarinus officinalis ‘Prostratus’): Covers poor soils
- Oleander (Nerium oleander): Long-flowering, tolerant Salinity
Perennials and Annuals
- Gazania (Gazania rigens): Colorful flowers, close at night
- Salvia greggii: Attracts pollinators, long blooms
- Echinacea purpurea: Medicinal and ornamental
Succulents
- Agave americana: Sculptural, requires no watering once established
- Sedum spectabile: Fall bloom for difficult areas
Xerophytic Garden Design by Style
Mediterranean Garden
- Color Palette: Grays, blue-greens, silvers
- Keystone Species: Lavender, santolina, cistus
- Elements: Pergolas, terracotta pots, gravel paths
Contemporary Desert Garden
- Geometric Structures: Clean lines, trimmed hedges
- Materials: Wood, corten steel, natural stone
- Architectural Plants: Yuccas, dasyllables Nolinas
Dry Meadow Garden
- Natural inspiration: A wild but controlled look
- Combinations: Grasses + flowering perennials
- Species: Stipa tenuissima, Echinops ritro, Gaura lindheimeri
Technologies that have revolutionized xeriscaping in 2025
Smart Irrigation Systems
- AI Control: Adjusts irrigation based on weather forecasts
- Underground Sensors: Measure actual moisture at different depths
- Integrated Platforms: Apps that manage the entire garden
Innovative Materials

- Smart Geotextiles: Control humidity and temperature
- Special Substrates: Mixtures with natural water retainers
Environmental and Economic Impact
Measurable Benefits
- Water Savings: 60,000 liters/year in an average garden (500 m²)
- Emissions Reduction: 85% less fuel for maintenance
- Biodiversity: 50% more pollinating insect species
Economic Savings
- Water Bill: €250-400 less/year
- Maintenance: 70% reduction in costs
- Capital Gains: 5-7% increase in property value
Success Stories International
Copenhagen Botanical Garden
- Area: 4 hectares completely xeriscaped
- Result: 82% less water than similar traditional gardens
- Innovation: Rainwater harvesting system + sustainable drainage
“Dry Garden” Project (London)
- Designer: Beth Chatto (pioneer xeriscaping)
- Location: Former gravel pit, poor soil
- Achievement: Zero supplemental irrigation from 2022
How to Implement Xeriscaping in 5 Steps
- Site assessment: Climate, soil, exposure, views
- Conceptual design: Zoning, style, plant palette
- Soil preparation: Improvement, leveling, irrigation installation
- Planting: Appropriate season, establishment techniques
- Initial maintenance: Deep irrigation for the first 2 years
Common Mistakes to Avoid
- Planting too young: Better to use smaller specimens that adapt better
- Watering frequently and infrequently: Promotes shallow roots
- Not improving the soil: Invest in Soil is an investment in a future garden
- Choosing inappropriate species: Investigating real needs
“A xeriscape is not a second-rate garden; it’s a garden of the future where each plant is in the perfect place to thrive with just the right amount” — Carlos Ribas, specialized landscaper.
