Want to save water and reduce yard maintenance? Xeriscaping can cut water use by up to 75% and slash lawn care costs by as much as 87%. But many people make mistakes that lead to disappointing results. Here’s how to avoid them:

• Plant Selection: Choose native plants suited to Maryland’s hot, humid summers and cold winters. Avoid overcrowding and group plants with similar water and light needs.
• Site Analysis: Understand your yard’s sun, shade, slope, and drainage patterns. Poor planning can lead to water runoff or stressed plants.
• Ground Covers: Use organic mulch to retain moisture and enrich the soil. Avoid excessive rock cover, which reflects heat and doesn’t improve soil quality.
• Water Management: Install drip irrigation and water deeply but less often to encourage strong roots. Use rain barrels or redirect downspouts to conserve water.
• Long-Term Maintenance: Regular weeding, pruning, and refreshing mulch are essential, especially during the first few years as plants establish.

Xeriscaping – Every Weed Control Mistake Possible

Plant Selection and Spacing Errors

Choosing the right plants and spacing them correctly is essential for creating a water-efficient and low-maintenance landscape. Unfortunately, many homeowners in Maryland rush these decisions, leading to long-term issues like struggling plants, wasted water, and higher upkeep demands.

Problems with Overcrowding Plants

One of the most common mistakes is selecting plants based solely on their initial size or appearance without considering how large they’ll grow. For instance, a small ornamental grass or shrub might look perfect for a tight space, but as it matures, it could end up crowding nearby plants or blocking pathways.

When plants are too close together, they compete for resources like sunlight, water, and nutrients. This competition can weaken them, making them more vulnerable to pests and diseases. In Maryland’s humid summers, overcrowding can also reduce airflow, encouraging fungal problems. To avoid these issues, research the mature width of each plant and provide enough space for growth. While the garden may look sparse at first, plants will naturally fill in over time.

Selecting Plants for Maryland’s Climate

Maryland’s climate poses unique challenges for gardeners, with hot, humid summers and cold, wet winters. Plants that thrive in arid regions, like the Southwestern United States, often struggle with Maryland’s humidity and temperature fluctuations. Instead, focus on species that can handle both drought and periods of heavy moisture.

For sunny areas, native plants like purple coneflower, black-eyed Susan, and native grasses are excellent choices. In shaded spots, opt for shade-tolerant species such as coral bells or wild ginger, which can handle the state’s variable weather conditions.

Grouping Plants by Water and Light Needs

Another frequent error is mixing plants with differing water and light requirements. For example, placing a water-loving plant next to one that prefers dry soil can lead to overwatering one and underwatering the other.

To avoid this, group plants with similar water needs together. Create irrigation zones by placing moisture-loving plants in areas where water tends to linger, like north- or east-facing slopes that receive less direct sunlight. Similarly, group plants based on their light preferences to ensure they thrive in their respective environments. This thoughtful arrangement not only boosts plant health but also enhances the water-saving efficiency of your xeriscape.

Site Analysis Mistakes: Sun, Slope, and Drainage

Overlooking a proper site analysis can lead to disappointing plant growth, water-related damage, and expensive fixes. It’s a step you can’t afford to skip if you want a thriving landscape.

Sun and Shade Pattern Effects on Plant Health

Understanding how sunlight moves across your yard is crucial for healthy plants. Many people assume a spot gets plenty of sun without observing how light changes throughout the day and across seasons. For instance, a sunny area in the morning might be shaded later in the day, or a location drenched in summer sunlight could end up in shade once trees are fully leafed out.

Here’s the deal: plants have specific light needs. Sun-loving plants generally require at least six hours of direct sunlight daily, while shade-friendly plants thrive with about three hours or less. If you plant a sun-loving species in too much shade, it may grow weak and spindly, with fewer blooms. Conversely, shade plants exposed to intense sun often develop scorched leaves – especially during Maryland’s hot summers.

Don’t forget about heat reflected off hard surfaces like patios, driveways, or light-colored walls. These areas can become much hotter than they appear, further stressing plants. To avoid these pitfalls, take the time to map your yard’s sun and shade patterns over a few weeks. Track where shadows fall at different times of the day and mark areas that get full sun (6+ hours), partial sun or dappled shade (3–6 hours), and full shade (less than 3 hours). Also, keep in mind how seasonal changes or growing trees might alter these patterns over time.

Slope and Drainage Problems

Once you’ve nailed down your yard’s light conditions, it’s time to assess its slope and drainage. Even small slopes can create water runoff issues, leaving higher areas dry and lower spots waterlogged. Steeper slopes are even trickier – they can wash away topsoil and flood lower zones, especially during Maryland’s heavy summer storms.

Grading mistakes, like directing water toward your home or failing to level soil properly around foundations, can lead to serious problems. Fixing grading and adding drainage systems can cost anywhere from $1,500 to $5,000, while repairing water-damaged foundations can exceed $5,000^[6]. To prevent these headaches, consider drainage solutions like French drains. These systems use a perforated pipe buried in a gravel-filled trench to redirect water safely away from problem areas. They’re a smart choice for maintaining a water-efficient xeriscape.

Retaining walls can also help by controlling erosion and creating flat planting spaces. When built with proper drainage gaps, they allow water to flow through while stabilizing slopes. For steep areas, terracing – dividing the slope into multiple flat levels – can turn unusable land into functional garden space.

Problem Areas Near Downspouts and Wet Zones

Downspouts and natural low spots are common trouble zones in a xeriscape. Water pooling near downspouts can keep soil overly wet, which isn’t ideal for drought-tolerant plants. Similarly, natural depressions may turn into temporary ponds after rainstorms, which can harm plants that need well-drained soil.

French drains are a reliable fix for areas where water tends to collect, efficiently diverting runoff away. Another option is creating a dry creek bed to channel water during storms, which also adds a decorative element to your yard. For persistent wet spots, consider building up the soil with organic material and aerating compacted areas to improve drainage. Rain gardens, planted with water-loving species, are another excellent solution. They capture and filter runoff while providing a habitat for local wildlife.

Their expertise ensures your xeriscape not only looks great but also withstands Maryland’s challenging conditions, no matter your yard’s layout or water flow issues.

Mulch and Rock Ground Cover Mistakes

The type of ground cover you choose plays a big role in how well your xeriscape performs in Maryland’s climate. Both mulch and rock can be effective in water-efficient landscaping, but using them incorrectly can lead to more headaches than benefits.

Using Too Much Rock Ground Cover

While rock ground cover might seem like a low-maintenance option, it comes with some significant downsides. For starters, rocks can trap heat, reaching 140–170°F during Maryland’s hot summers, compared to organic mulch, which stays around 80–85°F. This heat not only stresses plants but also increases water runoff, making it harder for water to soak into the soil. During Maryland’s heavy storms, this can overwhelm drainage systems, and smaller rocks often end up clogging storm drains ^[8].

"Rocks are fine as landscape accents, but gravel-gilded grounds aren’t ideal for widespread use." – City of Round Rock ^[8]

Rocks also don’t provide any nutrients to the soil. Over time, debris and leaves settle between the rocks, creating fertile ground for weeds – even with a weed barrier in place. Removing weeds from gravel is tough work, and getting rid of rocks later can be costly and labor-intensive ^[7].

A better approach is to use rocks sparingly as accents, borders, or in features like dry creek beds ^[8]. In shady areas, they can help reduce the growth of sun-loving weeds. If you’re placing rocks near streets or driveways, choose larger stones that are less likely to wash away during storms. Always use durable landscape fabric underneath to cut down on weed growth ^[7].

Now let’s look at how to get the most out of mulch for your xeriscape.

Proper Mulch Application

Applying mulch correctly can make a huge difference in plant health and water retention. A common mistake is piling mulch against tree trunks or plant stems. This traps moisture, which can lead to rot and attract pests ^[9].

Always leave at least one inch of space between mulch and plant stems or crowns. This allows for proper airflow and prevents moisture buildup. Aim for a mulch layer that’s 2–4 inches thick – enough to suppress weeds and conserve moisture without smothering plant roots ^[11].

Before applying mulch, prepare the area by pulling weeds, loosening the soil, and watering thoroughly ^[10]. Once the mulch is spread, give it a light watering to help it settle and stay in place ^[11].

In March 2025, Southwest Boulder & Stone recommended Montana Bark Nuggets Mulch for xeriscaping pathways and large areas. These nuggets, made from fir bark, decompose slowly and are excellent at suppressing weeds. For more delicate plants, they suggested Gorilla Hair Shredded Redwood Mulch, which has a fine texture that helps regulate soil temperature and prevent weed growth ^[10].

"Mulching is a cornerstone of successful drought-tolerant gardening." – Southwest Boulder & Stone ^[10]

Remember to refresh organic mulch annually as it breaks down. Occasionally fluffing it with a rake can also improve air circulation ^[11].

Organic Mulch vs. Rock Ground Cover

Choosing between organic mulch and rock ground cover depends on the specific needs of your xeriscape. Here’s a quick comparison to help you decide:

Organic mulches, like wood chips and shredded leaves, gradually improve the soil by adding nutrients as they decompose. They also help keep plant roots cool during Maryland’s hot summers. However, they need to be replaced every year or two and can sometimes wash away in heavy rain ^[13].

Rock ground cover works well in windy areas where organic materials might scatter, and it’s a safer choice in fire-prone zones. Rocks also add visual contrast and texture to your landscape. That said, they reflect heat, can create glare, and are difficult to remove if you want to redesign your yard later ^[13].

"A true xeriscape is a beautiful landscape composed of low water-use plants, native or adapted to the climatic conditions where they are planted. Organic or inorganic mulches are incorporated around the garden to reduce water loss. As a result, xeriscapes not only use less water but take less maintenance and are resilient to the challenges of dry climate gardening." – Noelle Johnson, Horticulturist, author of Dry Climate Gardening ^[2]

For most Maryland xeriscapes, a blend of organic and rock mulch works best. Use organic mulch around plants that benefit from soil improvement, and reserve rock mulch for pathways, borders, or areas where durability matters more than soil enrichment ^[12]. Whichever option you choose, maintaining a three-inch layer will help with weed control and moisture retention ^[13].

Poor Planning for Maintenance and Water Management

Building on the foundation of smart plant selection and site analysis, successful xeriscaping hinges on thoughtful long-term maintenance and water management. While xeriscapes require less upkeep compared to traditional lawns, they’re not entirely hands-off, especially in Maryland’s unique climate.

Long-Term Maintenance Planning

Xeriscapes still need regular care like weeding, mulching, irrigation, and pruning – particularly during the early years when plants are establishing their root systems. This establishment phase is critical, as consistent deep watering during this time helps plants develop strong, drought-resilient roots. It’s worth noting that while xeriscaping is low maintenance, it’s not maintenance-free ^[2].

Weeding is a particularly important task. Aggressive weeds, especially during Maryland’s wet spring season, can overtake even drought-tolerant and native plants if left unchecked. To keep your xeriscape thriving, create a schedule for essential tasks like weeding, pruning, and refreshing mulch. These efforts will help maintain soil health, control weeds, and keep the garden looking its best.

Irrigation systems also demand regular attention. Check drip irrigation lines for clogs, replace worn-out parts, and adjust watering schedules as plants grow and seasons change. Staying on top of these details ensures your xeriscape remains efficient and healthy over time ^[14].

Water Management Strategies

Good water management goes beyond choosing drought-tolerant plants. When properly planned, xeriscaping can cut water use by 50–75% compared to traditional landscaping ^[1]. The key? Water deeply but less often. This approach encourages plants to grow deep roots, unlike the shallow-rooted systems that result from daily watering.

Grouping plants with similar water needs, a practice known as hydrozoning, is another effective strategy. This ensures efficient watering without over- or under-watering certain plants ^[2]. Installing a drip irrigation system is also a game-changer. Drip systems deliver water directly to roots, minimizing evaporation and waste. For added efficiency, consider adding a moisture sensor to your system – this ensures sprinklers only activate when the soil is dry ^[15].

Rainwater can be an excellent supplemental resource. Redirect downspouts to garden beds or soaking areas, or install rain barrels or cisterns to collect water for drier periods ^[5]. Reducing turfgrass areas in favor of native groundcovers also significantly lowers water consumption ^[15].

"A true xeriscape is a beautiful landscape composed of low water-use plants, native or adapted to the climatic conditions where they are planted… Organic or inorganic mulches are incorporated around the garden to reduce water loss. As a result, xeriscapes not only use less water but take less maintenance and are resilient to the challenges of dry climate gardening."

FAQs

What are the advantages of using organic mulch instead of rock in xeriscaping, especially for Maryland’s climate?

Organic mulch brings plenty of benefits, especially in Maryland’s unpredictable climate. As it breaks down, it enriches the soil with nutrients and boosts its ability to retain water – something that’s incredibly helpful during those sweltering, dry spells. Plus, it helps regulate soil temperature, keeping roots cooler in the summer and warmer in the winter. On top of that, organic mulch suppresses weeds, cutting down competition for water and nutrients.

In contrast, rock ground cover, while easier to maintain, doesn’t offer these soil-improving perks. Rocks can even absorb and radiate heat, which might put extra stress on plants during Maryland’s hotter months. If you’re aiming for healthier plants and better soil, organic mulch is often the smarter pick for xeriscaping in this area.

How do I group plants with similar water and light needs for a successful xeriscape?

To design a successful xeriscape, start by taking a close look at your yard. Notice how sunlight and moisture vary across different areas. Use this information to divide your space into zones based on water needs – such as high, moderate, and low. For example, plants that need more water should be placed closer to your home or a water source, while drought-tolerant varieties can thrive farther away.

A helpful strategy here is hydrozoning, which means grouping plants with similar water and light needs together. This makes watering more efficient and helps avoid issues like overwatering or underwatering. Opting for native or drought-resistant plants is another smart move – they’re naturally suited to your local climate and require less upkeep. To further support your xeriscape, apply mulch around your plants. This helps the soil retain moisture, keeps weeds in check, and stabilizes soil temperature, creating an environment where your plants can flourish with minimal effort.

How can I manage water runoff and drainage issues in a xeriscape, especially on sloped or uneven ground?

Managing Water Runoff and Drainage in a Xeriscape

Dealing with water runoff and drainage in a xeriscape, especially on sloped or uneven ground, takes some careful planning. One smart approach is to incorporate swales – these are shallow trenches with gentle slopes that help capture and redirect water. Swales not only reduce erosion but also improve soil absorption, ensuring water stays where it’s most beneficial.

Another option is installing French drains, which are underground systems designed to move excess water away from trouble spots. Combine this with proper grading, where the land is sloped away from structures, and you can effectively minimize water pooling and erosion. Don’t forget to keep your gutters and downspouts clear, directing water to safe areas far from slopes. Together, these techniques ensure your xeriscape remains functional and thriving, even on tricky terrain.
