Creating a drought-resistant landscape means designing your outdoor space to thrive with minimal water. This involves choosing plants that require less watering, improving soil health, using efficient irrigation systems, and incorporating low-maintenance hardscaping. For Maryland homeowners, this approach is especially useful as droughts are predicted to become more frequent.
Key Takeaways:
- Save Water: Replace traditional turf with drought-tolerant plants to reduce outdoor water use by up to 75%.
- Choose Native Plants: Opt for species like Black-eyed Susans and Butterfly Weed that naturally handle dry conditions.
- Prepare Soil: Add organic matter to improve water retention and test soil drainage for optimal plant health.
- Efficient Irrigation: Use drip systems or soaker hoses to minimize water waste.
- Hardscaping: Incorporate permeable materials like pavers and gravel to manage water runoff effectively.
By combining these strategies, you can cut water bills, reduce maintenance costs, and create a landscape that withstands dry spells while supporting local ecosystems.
Designing a Drought Resistant Landscape
Assess Your Property’s Site Conditions
Once you’ve familiarized yourself with the advantages of drought-resistant landscaping, it’s time to take a closer look at your yard. Understanding the unique characteristics of your property is a critical first step before diving into design decisions.
Map Sun and Shade Areas
Knowing how sunlight moves across your yard helps you place the right plants in the right spots. For example, south-facing gardens bask in the most sunlight, while north-facing ones tend to stay shaded. East-facing areas catch the morning sun, while west-facing spaces soak up the warmer afternoon light.
To map your yard’s sunlight, try conducting a simple sun survey. Check how sunlight falls at different times of the day – around 8:00 a.m., noon, and 4:00 p.m. – to see which areas get the most light. Sketch your yard, noting the location of trees, fences, or structures that create shade. Then, label areas based on their sun exposure:
- Full sun: At least six hours of direct sunlight daily
- Partial shade: Two to six hours of direct sunlight, with shade the rest of the day
- Deep shade: Two hours or less of sunlight, often found in wooded areas
- Dappled sunlight (filtered shade): Light that filters through tree canopies, creating a mix of sun and shade
For the best results, map your yard during mid-summer when the sun is at its strongest. A compass can help you determine your yard’s orientation, or you could use a sun-tracking app like Sun Seeker for added precision.
Test Soil Type and Drainage
Your soil’s texture and drainage capacity directly affect plant health and water retention. Sandy soils drain quickly but hold fewer nutrients, while clay soils retain water but may have poor airflow and slow drainage. Loamy soil, on the other hand, strikes a balance and is often ideal for landscaping.
To figure out your soil type, grab a handful and feel its texture: sandy soil feels gritty, clay soil is sticky, and loamy soil crumbles easily. For more accuracy, try a jar test to examine the soil composition.
Drainage is equally important. To test it, dig a hole about 12 inches deep and wide, fill it with water, and let it drain completely. Then, refill the hole and measure how fast the water drains:
- Less than 1 inch per hour: Drainage is too slow
- 1–3 inches per hour: Ideal drainage
- More than 4 inches per hour: Soil drains too quickly
Most plants thrive in slightly acidic to neutral soil (pH 6.0–7.0). For a deeper look at your soil’s pH, nutrient levels, and texture, consider sending samples to a professional lab for testing. These findings will help you address any challenges and prepare your yard for drought-resistant plants.
Find Problem Areas
Before jumping into your landscaping project, identify any trouble spots in your yard that might need extra attention. Common issues include:
- Compacted Soil: Often caused by heavy foot traffic or construction, compacted soil prevents water from seeping in. Aerating the soil can help.
- Steep Slopes: Slopes can lead to erosion and runoff, making it hard for plants to take root and retain moisture. Deep-rooted ground covers and shrubs can help stabilize these areas.
- Poor Drainage: Look for spots where water pools after rain or irrigation. These areas may need solutions like French drains or dry creek beds to improve drainage.
- Soil pH Imbalances: Extreme pH levels can limit your plant options. Testing soil in multiple areas can reveal any inconsistencies, allowing you to amend the soil with organic matter if needed.
Select Drought-Tolerant Plants for Maryland
Once you’ve assessed your property’s conditions, it’s time to pick plants that can handle Maryland’s dry spells. The trick is to choose species that naturally thrive in such conditions.
Choose Native and Adapted Plants
Native plants are an excellent choice for creating a drought-resistant landscape. They’ve had thousands of years to adapt to Maryland’s unique weather and soil. As Homestead Gardens, Inc. notes:
"Native plants have evolved with a region’s climate and unique features for thousands of years…Many times they are better able to withstand local pests, diseases, and weather patterns, and perform better in local soil conditions than their cultivated counterparts." [3]
For instance, Black-eyed Susans (Rudbeckia), Maryland’s state flower, are naturally drought-tolerant [3][4]. These bright yellow flowers bloom from summer through fall, thriving in full sun and poor soil with little maintenance.
Another standout is Butterfly Weed (Asclepias tuberosa), a vibrant orange perennial that loves dry, sunny spots and attracts monarch butterflies [2][6]. Plant it in well-draining soil and watch it spread over time.
If you’re looking for shrubs, Northern Bayberry is a native option [6]. For grasses, Switchgrass (Panicum virgatum) is a versatile choice that handles both wet and dry conditions beautifully [5].
For groundcover, Pussytoes (Antennaria plantaginifolia) is a great pick. It thrives in full sun and dry soils, spreading into a compact, low-maintenance carpet [2].
To create a balanced landscape, mix shrubs, perennials, and grasses that cater to different moisture levels.
Add Shrubs, Perennials, and Grasses
Layering your landscape with shrubs, perennials, and grasses not only adds depth but also ensures water efficiency. Look for plants with smaller leaves, waxy surfaces, or fuzzy textures – features that help limit water loss [4].
Start with drought-tolerant shrubs to form the backbone of your design. Fragrant Sumac ‘Gro-Low’ (Rhus aromatica ‘Gro Low’) thrives in sunny, dry spots and can adapt to partial shade [2]. Other hardy options include Nandina, Spireas, Abelias, and Bush Clover [4].
For seasonal color, perennial flowers are a smart choice. Coneflower (Echinacea purpurea) loves dry soils and full sun [2]. Daylilies and Coreopsis bring extended blooms [4], while Eastern Bee Balm (Monarda bradburiana) does well in drier soils and partial shade [2].
Ornamental grasses add texture and movement with minimal water needs. Little Bluestem (Schizachyrium scoparium) offers striking color variations in full sun [2][5]. Other options like Prairie Dropseed (Sporobolus heterolepis), Purple Love Grass (Eragrostis spectabilis), and Blue Fescue (Festuca glauca) provide fine-textured accents and neat clumps [5].
Steer clear of invasive species like Chinese Silvergrass (Miscanthus sinensis) and Chinese Fountaingrass (Cenchrus purpurascens), which can spread aggressively [5].
Group Plants by Water Needs
Organizing plants based on their watering requirements, a technique called hydrozoning, can make irrigation more efficient [4]. This way, you can tailor watering to each area instead of applying the same amount everywhere.
- High-water zones: Place lush, green plants near entrances or outdoor living spaces.
- Medium-water zones: Use for mixed borders or transitional areas.
- Low-water zones: Reserve for your most drought-tolerant plants, especially in hard-to-reach spots.
Within each zone, consider the size and growth patterns of your plants. For example, taller shrubs like Blue False Indigo (Baptisia australis) work well at the back [2], medium-height perennials like Penstemon ‘Husker Red’ fit nicely in the middle [2], and low-growing groundcovers can fill in the front.
Timing is also crucial. Plant in the fall or early spring to give roots time to establish before the heat of summer [4]. Water new perennials regularly during their first year and shrubs for their first two years to help them settle in [2].
Prepare Soil and Add Mulch
Laying the groundwork for a drought-resistant landscape starts with proper soil preparation. Even plants that thrive in dry conditions need healthy soil to access water deep below the surface. As Jon Traunfeld from the University of Maryland Extension explains:
"Many experts believe that improving soil health is the most important thing we can do to make our farms and gardens more climate-resilient." [7]
Boosting Soil Quality
Adding organic matter is one of the simplest ways to improve soil’s ability to retain moisture. For instance, just 1% organic matter can release ½–1 pound of nitrogen per 1,000 square feet, helping plants endure dry spells. Soils with more than 4% organic matter often require little to no additional fertilizer [7].
Using soil test results, you can determine if lime or other fertilizers are necessary to balance your soil’s nutrients. Regularly incorporating organic materials like compost, well-aged manure, or leaf mold can significantly enhance water retention. A great tip is to apply a half-inch layer of compost to your lawn each spring – it’s a proven way to support healthy soil.
To maintain soil health, avoid excessive tilling, which can disrupt the beneficial organisms in the soil. Instead, focus on improving specific planting areas. Covering the soil year-round with groundcovers, plants, mulch, or cover crops can prevent erosion and slow evaporation. Plus, planting a diverse range of vegetation creates varied soil conditions that support overall health. By minimizing tilling and consistently adding organic matter, you can build soil that’s better equipped to handle drought conditions [7].
Mulch: A Moisture-Saving Essential
Mulch plays a key role in conserving water in your garden. As Joe Lamp’l, creator of joe gardener®, puts it:
"The single best thing you can do to improve your watering efficiency is to add mulch to your garden beds." [12]
Mulch can reduce water loss by up to 60% by shielding the soil from direct sunlight and slowing evaporation. It also lowers soil temperatures by 8–13°F, further reducing moisture loss [10][14].
For the best results, opt for coarse organic mulches like shredded wood or wood chips. Popular choices for drought-tolerant gardens include bark nuggets and shredded redwood mulch [8][9]. Avoid fine-textured mulches like sawdust or those with waxy components, as they can repel water. Also, steer clear of inorganic mulches such as stones or synthetic rubber, which may increase soil temperatures and water loss [14].
Apply mulch in a 2- to 4-inch layer to maximize its moisture-retaining benefits. For coarse inorganic mulches, a 3- to 4-inch layer works well, but always start with moist, weed-free soil. Keep mulch a few inches away from plant stems and trunks to prevent rot [13][15]. For newly planted areas, wait until plants are established before adding a 2- to 3-inch mulch layer, ensuring there’s a gap around the plant bases. Replenish mulch annually to maintain its effectiveness – bark nuggets can last 2 to 3 years, while shredded mulches often need yearly replacement [8][9].
In addition to conserving water, mulch suppresses weeds, prevents erosion, and gradually enriches the soil as it breaks down [12][11]. These steps in soil preparation and mulching lay the groundwork for a water-efficient and resilient landscape.

Install Water-Efficient Irrigation Systems
Once your soil is prepped, it’s time to install an irrigation system that prioritizes getting water directly to plant roots. Traditional sprinklers often waste water through evaporation or wind drift, but efficient irrigation systems focus on delivering moisture exactly where it’s needed. Think of it as the next step in ensuring your plants thrive while minimizing water waste.
Install Drip Irrigation or Soaker Hoses
Two of the most effective options for water-efficient irrigation are drip irrigation systems and soaker hoses. These methods are designed to deliver water slowly and directly to the root zone, where it can be absorbed effectively, reducing water loss and helping prevent issues like fungal diseases.
Drip irrigation systems consist of a network of tubes with small emitters that release water at a slow rate – typically 1 to 4 gallons per hour. This gradual delivery ensures water soaks deeply into the soil instead of running off. They’re particularly effective for trees, shrubs, and perennial beds, as you can customize water distribution for each plant’s needs.
Soaker hoses, on the other hand, are a simpler and budget-friendly option. These porous hoses "sweat" water along their length, providing consistent moisture for linear plantings like vegetable rows or hedgerows. They’re easy to set up and have a lower upfront cost, making them a great choice for beginners looking to improve irrigation efficiency.
For both systems, consider connecting them to automated timers and laying the lines beneath mulch. This setup minimizes evaporation and protects the equipment from UV damage, ensuring better performance and longevity.
Follow Smart Watering Practices
Efficient irrigation isn’t just about the system you choose – how and when you water plays a big role too. Water deeply but less often to encourage plants to develop strong, deep root systems that can access moisture stored further down in the soil.
Timing is everything. Water early in the morning, ideally between 4:00 AM and 10:00 AM. This timing reduces evaporation and gives plants a chance to dry off before evening, which helps prevent fungal issues. Avoid watering during the heat of midday, when evaporation is at its peak, or in the evening, when wet leaves can lead to disease.
Adopt a flexible watering schedule that adjusts to weather conditions. For example, if your area receives ½ inch or more of rain, you can skip your next scheduled watering. Seasonal adjustments are also essential – newly planted drought-tolerant species need consistent watering during their first growing season to establish roots, but once they’re established, they can often rely on rainfall alone except during extended dry spells. As fall approaches and temperatures drop, reduce watering frequency accordingly.
Maintaining your irrigation system is just as important as setting it up. A well-maintained system can use up to 15% less water than one that’s neglected. Check your system monthly during the growing season for issues like clogged emitters, damaged hoses, or misaligned sprinkler heads. Flush the system annually to remove mineral buildup and keep it running smoothly.
Keep an eye on your water usage to catch problems early. A sudden spike in your water bill could signal a leak or malfunction in your system. For added convenience, consider using smart irrigation controllers with weather sensors. These devices adjust watering schedules based on real-time conditions like temperature, humidity, and rainfall, ensuring your plants get exactly what they need without wasting water [16].
Add Hardscaping and Water-Smart Features
In addition to efficient irrigation methods, incorporating hardscaping is a smart way to both reduce water usage and enhance the functionality of outdoor spaces. Hardscaping replaces thirsty lawns with durable, low-maintenance features that don’t require irrigation. These permanent elements not only save water but also create structured, usable spaces that look great year-round.
Use Permeable Materials
Permeable materials, like pavers and gravel walkways, play a key role in managing water in drought-friendly landscapes. Unlike traditional concrete, which directs rainwater to storm drains, permeable surfaces allow water to seep into the ground, replenishing surrounding plants.
The Interlocking Concrete Pavement Institute (ICPI) highlights that permeable interlocking concrete pavement (PICP) systems can reduce peak water flow by up to 90%, making them ideal for areas with heavy foot traffic[17]. A great example is the DEA Museum in Arlington, Virginia, where 18,000 square feet of permeable pavers were installed. This design not only manages stormwater but also supports sustainability goals by using an aggregate base that promotes water infiltration and creates an underground detention system[17].
Dry creek beds are another effective option for managing runoff. These features use river rock and gravel to mimic natural streams, directing water during heavy rains while adding a decorative, low-maintenance element to the landscape.
Pairing permeable materials with native plants along edges enhances water management even further. Native plants act as natural filters, improving water quality and supporting local ecosystems. Combined with low-maintenance hardscaping, these features create a balanced, water-efficient outdoor environment.
Create Low-Maintenance Outdoor Areas
Features like stone patios and natural stone steps are excellent alternatives to water-intensive lawns. A thoughtfully designed flagstone patio, for instance, eliminates the need for watering, mowing, or fertilizing, while offering an inviting space for outdoor gatherings.
Retaining walls can serve dual purposes: they create level planting areas on slopes and can include built-in planters for drought-tolerant plants. Natural stone retaining walls also add vertical interest and can incorporate seating, blending functionality with visual appeal.
Decomposed granite pathways are another water-efficient option. They provide a softer, natural look, offer great drainage, and work well with various garden designs. This material compacts firmly underfoot while allowing water to penetrate, maintaining a clean and polished appearance. These low-maintenance solutions are the foundation of expert hardscaping designs.

Start by keeping an eye on soil moisture with a moisture meter, aerating compacted areas, and adding compost when necessary [18]. During the growing season, prune dead or damaged branches, but avoid over-pruning to keep your drought-tolerant plants healthy and stress-free [18].
Adjust your mulching practices with the seasons – reapply mulch to help retain moisture, regulate soil temperature, and protect plant bases. Pair this with smart irrigation tools like timers and moisture sensors to maintain efficiency throughout the year [18]. Additionally, focus on watering techniques that promote resilience.
Water deeply but less frequently to encourage strong, deep root systems, and group plants with similar water needs together. Water either early in the morning or late in the evening to reduce evaporation, and raise your lawn mower blades to encourage deeper root growth in grass [1][18].
Stay proactive with pest and weed management to protect your landscape and optimize water efficiency. Use natural solutions like beneficial insects or eco-friendly treatments such as neem oil, and remove weeds by hand or pre-treat them. Consistent mulching also helps keep weeds under control [18].
