Drought-Tolerant Lawn Grass: A Guide to Choosing and Maintaining a Water-Wise Lawn

What is Drought-Tolerant Lawn Grass?

Drought-tolerant lawn grasses are specifically bred or selected for their ability to withstand extended periods of water scarcity. These grasses have evolved natural adaptations or have been cultivated to minimize water loss and survive in arid conditions.

Benefits of Drought-Tolerant Lawns

  • Conserve water, reducing utility bills and environmental impact.
  • Reduce the need for supplemental irrigation, saving time and effort.
  • Maintain a lush, green lawn even during dry spells.
  • Increase the resilience of your lawn to climate change and water restrictions.

Choosing the Right Drought-Tolerant Grass

The best drought-tolerant grass for your lawn will depend on your specific climate, soil conditions, and desired lawn characteristics. Consider the following factors:

  • Cool Season Grasses: These grasses thrive in cooler temperatures and require more frequent watering than warm-season grasses. Suitable cool season drought-tolerant grasses include tall fescue, sheep fescue, and wheatgrass varieties.
  • Warm-Season Grasses: These grasses prefer warm temperatures and can survive on less water during their peak growing season. Drought-tolerant warm-season grasses include Bermudagrass, St. Augustine grass, Zoysia grass, centipede grass, and Bahia grass.

Cultural Practices for Drought Tolerance

In addition to selecting a drought-tolerant grass, proper cultural practices can further enhance its water-saving capabilities:

  • Deep Infrequent Watering: Water your lawn deeply and infrequently rather than shallowly and frequently. This encourages deep root growth and reduces water loss through evaporation.
  • Healthy Soil: Amend your soil with organic matter to improve water retention and nutrient availability. Healthy soil promotes strong root development and overall plant health.
  • Appropriate Mowing Height: Mow your lawn at a species-appropriate height to reduce stress and water loss. Taller mowing heights promote deeper root growth and shading of the soil.

Drought-Tolerant Lawn Grass Cultivars

Within each grass species, there are specific cultivars that have been bred for enhanced drought resistance. Some notable drought-tolerant cultivars include:

  • Cool Season Grasses:
    • Tall Fescue: ‘Rebellion’ and ‘Reveille’
    • Sheep Fescue: ‘Durar’ and ‘Harding’
    • Wheatgrass: ‘Blue Grama’ and ‘Western Wheatgrass’
  • Warm-Season Grasses:
    • Bermudagrass: ‘Celebration’ and ‘TifSport’
    • St. Augustine Grass: ‘Floratam’
    • Zoysia Grass: ‘El Toro’ and ‘Empire’
    • Centipede Grass: ‘TifBlair’ and ‘Emerald’
    • Bahia Grass: ‘Pensacola’ and ‘Argentine’

Dormant Grass

During extreme drought conditions, some grasses may turn yellow and go dormant to conserve water. Dormant grass is not dead and will recover once it receives adequate moisture. Avoid excessive foot traffic on dormant grass to prevent damage.

Tips for Maintaining a Drought-Tolerant Lawn

  • Choose the right grass for your climate and soil conditions.
  • Water deeply and infrequently.
  • Maintain healthy soil by adding organic matter.
  • Mow your lawn at an appropriate height for the species.
  • Fertilize your lawn according to soil test recommendations.
  • Aerate your lawn regularly to improve water penetration.
  • Reduce foot traffic on dormant grass during extreme drought.

By following these tips, you can establish and maintain a beautiful, drought-tolerant lawn that will thrive even during water-scarce conditions.

Growing a Lush Lawn in Dry Conditions: A Comprehensive Guide

Watering Strategies for Arid Climates

In dry regions, water conservation is paramount. To maintain a healthy lawn, it’s crucial to water correctly and efficiently.

  • Watering Frequency: Contrary to popular belief, overwatering can weaken your lawn. Aim for 1 to 1.5 inches of water per week, deeply watering less frequently.

  • Watering Technique: Water in the morning to minimize evaporation. Avoid watering on windy days or during intense heat.

Adapting to Summer Heat

During the scorching summer months, your lawn needs special care.

  • Reduce Foot Traffic and Maintenance: Limit activities on the lawn and postpone aeration and dethatching until cooler seasons.

  • Mow at a Taller Height: Grass blades store moisture. By mowing at a taller height, you provide shade for the soil, reducing moisture loss.

  • Reduce Stress During Drought: Avoid major lawn maintenance during dry periods and prioritize the root system by watering deeply to keep it alive.

Choosing Drought-Tolerant Grasses

Some grass species are more resilient to water scarcity than others.

  • Cool-Season Grasses: Fescue varieties are known for their drought tolerance, requiring less water than Kentucky bluegrass, the traditional choice for cool-season climates.

  • Warm-Season Grasses: Warm-season regions offer a wide range of drought-tolerant grass species, including cultivars bred specifically for arid environments.

Proper Mowing Practices

Mowing plays a significant role in lawn health.

  • Mow at the Right Height: In dry conditions, mow at a higher height to preserve moisture and shade the soil.

  • Avoid Mowing During Drought: Suspend mowing during drought periods to minimize stress on the grass.

Enriching the Soil

Healthy soil supports a thriving lawn.

  • Amend the Soil: Incorporate organic matter or compost into the soil to improve its moisture retention capabilities.

  • Use a Mulching Mower: Leave grass clippings on the lawn to provide organic material and retain moisture.

Consider Lawn Downsizing

In areas with severe water scarcity, reducing the size of your lawn can be a practical solution.

  • Create Non-Lawn Spaces: Add decks, patios, or other hardscapes to reduce the need for water-intensive grass.

  • Downsize the Lawn: Make the remaining lawn smaller and more manageable, focusing on areas used for activities or aesthetics.

Alternative Groundcovers

For regions with permanent water scarcity, consider replacing grass with alternative groundcovers that require less water.

  • Shady Areas: Periwinkle, creeping mahonia, sweet woodruff, and creeping thyme are suitable groundcovers for shaded areas.

  • Sunny Areas: Rockrose, snow in summer, moss phlox, and winecups thrive in sunny, dry conditions.

Artificial Grass

Artificial grass offers a water-saving alternative to traditional lawns.

  • Low Maintenance: Artificial grass requires minimal maintenance, eliminating the need for watering, mowing, and fertilizing.

  • Realistic Appearance: Advancements in technology have resulted in synthetic turf that closely resembles natural grass, both in appearance and texture.

Fertilizing During Dry Conditions

Fertilizing your lawn during dry periods should be done cautiously.

  • Avoid Nitrogen Fertilizer: Overfertilizing with nitrogen can burn the lawn in hot, dry conditions.

  • Fertilize in Fall or Winter: Apply fertilizer when the weather is cooler to promote healthy growth without causing stress.

Frequently Asked Questions

  • Should you water your lawn every day during a drought? No, deep watering several times a week is more effective than daily watering.

  • What happens when grass gets too dry? Drought-stressed grass may wilt and turn brown, but can recover with proper watering and ideal temperatures.

  • Is it better to keep grass long or short in a drought? Longer grass keeps the soil cooler and reduces evaporation, promoting a stronger root system.

Rain Gardens: A Natural Solution for Stormwater Management

What is a Rain Garden?

A rain garden is a landscaped depression planted with native plants that capture, temporarily hold, and filter stormwater before it enters storm sewer systems. Rain gardens mimic natural ecosystems and provide numerous benefits, including reducing runoff, improving water quality, and creating wildlife habitats.

How Rain Gardens Work

Rain gardens work by slowing down and infiltrating stormwater runoff from impervious surfaces such as roofs, driveways, and patios. The plants in the garden absorb the water through their deep roots, which helps to filter out pollutants and prevent erosion. The water is then slowly released back into the ground, replenishing groundwater supplies and reducing the risk of flooding.

Benefits of Rain Gardens

  • Water Conservation: Rain gardens capture and store stormwater, reducing the amount of water that flows into storm sewers. This helps to conserve water resources and reduce the strain on municipal water systems.
  • Water Quality Improvement: The plants in rain gardens absorb pollutants from stormwater runoff, such as excess nutrients, oils, and sediments. This helps to improve the quality of water in local waterways.
  • Erosion Control: The deep roots of native plants in rain gardens help to stabilize soil and prevent erosion. This is especially important in areas with steep slopes or unstable soils.
  • Wildlife Habitat: Rain gardens provide food and shelter for a variety of wildlife, including birds, butterflies, and frogs. The diverse plant life attracts insects, which in turn attract birds and other animals.
  • Aesthetics: Rain gardens can be designed to be beautiful and functional. They can be incorporated into existing landscapes or created as standalone features.

Planning a Rain Garden

The first step in planning a rain garden is to choose a suitable location. The garden should be located in a low spot in your landscape that receives runoff from impervious surfaces. It should also be at least 10 feet away from your home to prevent water damage to the foundation.

The size of the rain garden will depend on the amount of runoff you expect to receive. A small garden is better than none, but a larger garden will be more effective at capturing and filtering stormwater.

Once you have chosen a location, you need to prepare the soil. The soil should be well-drained and amended with organic matter to improve its water-holding capacity.

Choosing Plants for a Rain Garden

The plants you choose for your rain garden should be native to your area and adapted to the local climate and soil conditions. Native plants have deep roots that help to absorb stormwater and prevent erosion. They are also more likely to attract wildlife.

When choosing plants, consider the following:

  • Edges: Plants on the edge of the garden should be able to tolerate dry conditions.
  • Slopes: Plants on slopes should be able to thrive in both wet and dry conditions.
  • Base: Plants in the center of the garden will experience longer periods of wet soil and should be able to tolerate these conditions.
  • Focal Point: You can add a small ornamental tree or shrub to serve as a focal point for the garden.

Planting and Maintenance

Once you have chosen your plants, it is time to plant them in the rain garden. Dig holes that are twice as wide as the root balls and just as deep. Place the plants in the holes and backfill with soil, tamping down gently to remove any air pockets.

Water the plants deeply after planting. Rain gardens typically require less watering than traditional gardens, but they may need supplemental watering during extended dry periods.

To keep your rain garden healthy, it is important to weed regularly, mulch around the plants to suppress weeds and retain moisture, and fertilize lightly in the spring.

Conclusion

Rain gardens are a beautiful and effective way to manage stormwater runoff and improve water quality. They are relatively easy to install and maintain, and they provide numerous benefits for both the environment and your landscape.
