    Site Assessment and Planning

  • Analyze sun exposure and shade patterns throughout the day and seasons to match plants with appropriate light conditions.
  • Evaluate soil type and drainage by conducting simple percolation tests. Most drought-tolerant natives prefer well-draining soils.
  • Identify microclimates in your landscape—areas that may be warmer, cooler, wetter, or drier than surrounding spaces.
  • Consider topography and how water naturally flows across your property during rainfall events.
  • Create a scaled drawing of your space, noting existing features to keep and areas for new plantings.

    • Design Principles for Water Conservation

    Hydrozone Grouping

    Arrange plants with similar water requirements together to prevent overwatering some species while underwatering others. This practice, known as hydrozoning, allows for more efficient irrigation and healthier plants.

    Strategic Plant Placement

    Position higher water-use plants in naturally moister areas like depressions or shade. Reserve the driest, hottest spots for the most drought-resistant species. Consider mature size to minimize future maintenance.

    Incorporate Hardscaping

    Integrate non-plant elements like boulders, gravel paths, or dry stream beds to reduce the total planted area while adding visual interest and functionality. These features can also help direct and capture rainwater.

    Create Habitat Layers

    Include a mix of groundcovers, perennials, shrubs, and trees to mimic natural plant communities. This layered approach provides diverse wildlife habitat while creating visual depth in your landscape.

    Installation Best Practices

  • Plant during cooler seasons to give roots time to establish before summer heat arrives.
  • Space plants appropriately according to their mature size to promote good air circulation and reduce competition for water.
  • Create watering basins around new plants to direct water to root zones during establishment.
  • Apply organic mulch 2-4 inches deep, keeping it away from plant stems to prevent rot while reducing evaporation and suppressing weeds.
  • Install efficient irrigation if needed, preferably drip systems that deliver water directly to root zones with minimal waste.

    Maintaining Your Native Drought-Tolerant Landscape

    One of the greatest benefits of native drought-tolerant landscapes is their reduced maintenance requirements. However, some care is still needed, especially during the establishment period and seasonal transitions.

    Establishment Period Care

  • Water deeply but infrequently during the first 1-2 years to encourage deep root growth. Even drought-tolerant plants need regular water until established.
  • Monitor new plantings closely for signs of stress, adjusting irrigation as needed based on weather conditions and plant responses.
  • Protect young plants from extreme heat or cold during their first year with temporary shade or frost covers if necessary.
  • Remove weeds promptly to reduce competition for water and nutrients while plants are establishing.

    • Seasonal Maintenance

  • Spring: Prune winter damage, divide spreading perennials if needed, refresh mulch, and check irrigation systems.
  • Summer: Deadhead spent flowers to encourage rebloom, monitor for pest issues, and adjust irrigation during extreme heat.
  • Fall: Plant new natives, collect seeds for propagation, reduce watering as temperatures cool, and leave seed heads for wildlife.
  • Winter: Minimize pruning except for safety concerns, reduce or eliminate irrigation depending on natural rainfall, and plan for spring additions.

    Long-Term Sustainability Practices

  • Avoid fertilizers in established native gardens, as excess nutrients can reduce drought tolerance and flowering while promoting unwanted growth.
  • Practice natural pest management by encouraging beneficial insects and accepting some level of damage as part of a healthy ecosystem.
  • Allow some self-seeding to create naturalistic plant communities that evolve over time.
  • Maintain plant diversity by adding new native species periodically to increase resilience and habitat value.
  • Harvest rainwater through passive systems like swales or active collection in rain barrels to supplement irrigation during dry periods.
