Virtual Series: Adding Natives to Existing Landscaping

Assessing Your Current Garden Beds

Before diving into native plant additions, it’s essential to get a clear picture of your garden’s current conditions. Take note of factors like sunlight, soil quality, and existing plant life to make informed decisions about what to plant and where.

Checking Sunlight and Shade Areas

Knowing how sunlight moves through your garden is crucial for successful planting. Creating a sun map can help you identify the best spots for different native species. Ideally, observe your garden over the course of a year – winter observations are particularly helpful since shadows are at their longest. You can take hourly photos or mark light patterns with flags to create a detailed light map.

David Holmgren from Retrosuburbia offers insight:

"In all but hot, dry inland climates, more sun exposure is better than less. Even in warmer climates it is easier to add shade by planting productive trees and vines in the right locations than it is to do much about lack of sun." ^[3]

To get precise measurements, use a sun-tracking or compass app to gauge sunlight direction and intensity. Label areas as full sun, partial sun (morning or afternoon), dappled shade, or full shade. Keep in mind that south-facing gardens typically receive the most sunlight, while north-facing areas get the least. Trees and their canopies can also block light – if dense shade is a problem, consider trimming lower branches to let more light through.

Once you’ve mapped out your garden’s light conditions, it’s time to evaluate your soil’s suitability for native plants.

Testing Your Soil Quality

The health of your soil plays a big role in how well native plants will grow. Fall is an ideal time for soil testing, as it allows you to address any issues before planting season begins.

Bob Westerfield, a horticulturist with UGA Extension, emphasizes:

"Testing your soil is always the first step to successful gardening." ^[4]

Start by collecting soil samples from a depth of 4–6 inches across different areas of your garden. Mix these samples together for a representative blend. Next, test the soil’s pH, which affects how plants absorb nutrients. Most North American soils are slightly acidic, with a pH range of 6 to 7. You can use DIY kits, digital pH meters, or send samples to a university extension lab for a detailed analysis.

To assess soil texture, rub a moist sample between your fingers – healthy soil typically contains about 20% clay, 40% silt, and 40% sand ^[5]. Drainage is another critical factor: dig a one-foot-deep, four-inch-wide hole, fill it with water, and measure how long it takes to drain. Poor drainage can be just as harmful as drought conditions. Lastly, check for earthworms – a healthy soil sample with 10 or more worms usually indicates good nutrient levels. While home testing kits are convenient, professional testing through your local county extension office can provide more accurate results.

With your soil tested, the next step is to evaluate your existing plant life.

Cataloging Current Plants and Problem Species

Take stock of the plants already in your garden to decide what to keep, remove, or replace. This step is especially important for managing invasive species, which are a major environmental and economic issue. In the United States alone, invasive species cost over $100 billion annually and contribute to the decline of 42% of endangered and threatened species ^[6].

Identify invasive plants in your garden. Many of these were originally introduced as ornamental plants but have since become harmful to local ecosystems. Common examples include Japanese Honeysuckle, Garlic Mustard, Japanese Barberry, Winter Creeper, and Norway Maple.

Make a list of plants that are thriving versus those that are struggling. Consider replacing invasive species with native plants to create a healthier, more balanced ecosystem. Regularly monitoring your garden for new invasive growth is essential for maintaining its health and supporting the surrounding environment.

Preparing Soil for Native Plants

Once you’ve assessed your garden’s conditions, it’s time to get the soil ready for your native plants. While native plants are well-suited to local soils, a few small tweaks can help them settle in more easily, especially in established garden beds. These simple adjustments can set the stage for their success.

Adding Organic Matter to Soil

Native plants generally don’t need dramatic changes to the soil, but a light layer of organic matter can work wonders. It boosts nutrients, supports helpful microorganisms, and improves both soil structure and moisture retention. The best approach for existing beds is to topdress rather than dig deeply into the soil. For instance, you can spread a thin ½-inch layer of organic matter, like worm castings or compost, around your plants each spring ^[9]. Other effective options include shredded leaves or homemade compost. Just be sure to keep these materials 3 to 5 inches away from plant stems or tree trunks to prevent moisture-related issues.

If you’re expanding a bed or creating new planting areas, mix 1 to 3 inches of organic matter into the top 6 to 12 inches of soil. A garden fork is perfect for loosening and aerating the soil without disturbing existing roots. In Maryland, for example, leaf compost works particularly well since it mimics the natural forest floor environment many native plants thrive in.

Managing Weeds Effectively

Weeds can steal water, nutrients, and space from your native plants, so keeping them in check is vital. A great way to prevent weeds is by applying 2 to 3 inches of organic mulch – like shredded bark, leaves, or wood chips – around your plants and in new planting zones. Mulch not only blocks sunlight to suppress weed growth but also helps the soil retain moisture.

When it comes to removing weeds, timing and technique matter. Pull them when the soil is moist, and use a hoe for dry conditions. For stubborn weeds along lawn edges, use a sharp knife to slice roots cleanly, minimizing soil disruption. To further discourage weeds, drip irrigation or soaker hoses can direct water to your plants while keeping weeds thirsty ^[10][11].

Making Space for New Plants

Adding native plants to an established garden requires careful planning to avoid damaging existing root systems. Start by clearing out unwanted vegetation – like grass, invasive species, or underperforming plants – and dig holes that are twice as wide as the plant pot to give roots plenty of room to grow. You may need to repeat vegetation removal to exhaust the weed seed bank.

If you’re removing larger plants, such as shrubs or trees, think about how this might change light and water availability for the surrounding plants. For instance, removing a dominant tree could create a sunny spot perfect for native wildflowers or a drier area suited to drought-tolerant species.

When preparing your soil for native plants, focus on improving drainage rather than trying to enrich fertility. In heavy clay soils, lining the bottom of planting holes with gravel or coarse sand can help water flow more freely ^[8]. Planting in stages can also be a smart move, allowing you to monitor how your new additions perform and adjust as needed.

As landscape designer Peyton Ellas explains:

"The only truly terrible soil is sterile, filled with pathogens or an over-abundance of salt or boron." ^[7]

Even soils that seem challenging at first can usually support native plants with just a little preparation. Prioritize good drainage and weed control over extensive soil modifications, and you’ll be well on your way to a thriving native garden.

Selecting Native Plants for Maryland Gardens

Maryland’s diverse environments make it crucial to choose native plants that align with your garden’s specific conditions. Using the observations you’ve already made about sunlight, soil, and moisture, you can select plants that will thrive in your space. The goal? A garden that’s not only beautiful but also supports local ecosystems.

To keep your garden vibrant and buzzing with life, consider plants with staggered bloom times. This ensures constant color while providing food for pollinators throughout the growing season. Whether you’re aiming to attract birds, support native insects, or simply enhance your garden’s visual appeal, Maryland natives like the Black-Eyed Susan – a hardy and stunning state flower – are excellent choices for combining beauty and ecological benefits ^[12].

Plants for Wet or Flood-Prone Areas

If you’ve got areas in your garden that stay damp or occasionally flood, it’s important to choose plants that can handle these conditions. First, figure out if the moisture is due to poor drainage or a naturally high water table. A simple way to check is by digging a 2-foot-deep hole and seeing if water collects after a few hours ^[14].

For consistently wet spots, consider options like Cardinal Flower, Great Blue Lobelia, Joe Pye Weed, and Rosemallow. These plants not only tolerate wet conditions but also bring color and life to your garden. Cardinal Flower’s red blooms and Great Blue Lobelia’s blue flowers are magnets for hummingbirds and butterflies. Joe Pye Weed adds vertical interest, while Sensitive Fern creates lush ground cover. For showy flowers, Rosemallow is a standout, and Summersweet offers fragrant white blooms that thrive in both wet and dry conditions once established ^[15].

Drought-Resistant Plants for Dry Areas

Maryland summers can be hot and dry, but native drought-resistant plants are up to the challenge. Black-Eyed Susan thrives in dry conditions, delivering bright yellow blooms from summer through fall ^[12]. Butterfly Weed is another favorite, with its vibrant orange flowers that attract monarch butterflies. Wild Bergamot, with its purple blooms and aromatic leaves, adds a touch of charm to dry gardens.

For grasses, Little Bluestem is a great pick, turning a striking bronze-red in the fall, while Yellow Indiangrass adds graceful movement in the breeze. Both perform well in sunny, well-drained areas. Other standout options include Foxglove Beardtongue, known for its tubular flowers that hummingbirds love, and New York Ironweed, which provides late-season purple blooms for vertical interest ^[15].

Native Shrubs and Ground Cover Options

Native shrubs add structure to your garden and often provide berries that birds adore. Spicebush, for example, thrives in partial shade and offers small yellow flowers in early spring. Virginia Sweetspire is another versatile option, with fragrant white flower spikes and stunning fall foliage. For winter interest, Winterberry Holly produces bright red berries that persist through the colder months. Black Chokeberry and Red Chokeberry also deliver seasonal blooms and berries, while Smooth Hydrangea offers large, evolving flower heads throughout the season ^[15].

Ground covers are perfect for filling in gaps and keeping weeds at bay. Wild Ginger creates a lush carpet in shaded areas with its heart-shaped leaves, while Foamflower adds delicate white blooms under trees. Christmas Fern stays green all year and handles a range of moisture conditions. For sunny spots, Green and Gold forms cheerful colonies, and Moss Phlox creates colorful carpets that work beautifully on slopes or in rock gardens ^[13].

To ensure success, choose plants sourced from local populations and within the mid to northern parts of their natural range. This helps guarantee they’re well-suited to Maryland’s specific climate ^[17]. For more guidance, resources like the University of Maryland Extension, Maryland’s Department of Natural Resources, and the Maryland Native Plant Society can provide detailed advice. You might also find tools like the Missouri Botanical Garden Plant Finder or the Lady Bird Johnson Native Plants Database helpful for exploring plant characteristics and care tips ^[14][16].

Planting and Care Instructions for Native Plants

Once your soil is ready, these planting and care tips will help you create a thriving native garden. The first year is especially important for helping plants establish strong roots and adapt to their new surroundings.

How to Plant Native Species Correctly

With your soil prepped, follow these steps to give your native plants the best start. Dig a hole slightly wider than the plant’s container and match the depth so the plant sits level with the surrounding soil – this helps prevent root rot and encourages healthy growth ^[18]. When removing the plant from its container, gently push from the bottom. If the roots are tightly bound, carefully loosen them to encourage outward growth. Once planted, pat the soil around the base to remove air pockets without compacting it too much. Avoid planting during hot, dry weather; early spring or fall provides better conditions for new plants to establish.

After planting, focus on consistent watering and mulching to help your garden flourish.

Watering and Mulching Requirements

Right after planting, water thoroughly to settle the soil. For the first two weeks, water daily to help the roots establish. After that, reduce watering to 2–3 times a week. In following years, you’ll only need to water deeply during extended dry periods ^[20][21].

Add a 2–3 inch layer of organic mulch around your plants, keeping it away from the stems. This helps retain moisture and keeps weeds at bay ^[19][22][23]. Over time, as your plants mature, allow natural plant litter like fallen leaves to remain. This mimics a forest floor, creating a nutrient-rich layer that benefits your garden.

Once your watering and mulching routine is in place, turn your attention to managing pests and removing problem plants.

Watching for Pests and Problem Plants

Keep an eye on your garden regularly to spot potential issues early. While native plants are generally resistant to pests due to their natural adaptation to local conditions, newly planted specimens can still face challenges. During the first year, weed the area frequently to prevent unwanted plants from competing for water and nutrients. Hand-pull small weeds when the soil is moist, and use tools for larger patches, being careful not to disturb nearby roots.

If pests become a problem, use an Integrated Pest Management (IPM) approach. Start by identifying which insects are harmful and which ones are beneficial to your garden ^[24]. Begin with physical methods, like removing infested plant parts or using a strong spray of water to control pest populations. You can also adopt cultural practices, such as maintaining healthy soil and clearing plant debris. If further intervention is necessary, choose less harmful options like insecticidal soaps or plant-based oils ^[24]. Avoid conventional pesticides and herbicides, as they can harm beneficial organisms and disrupt the soil ecosystem ^[18].

Conclusion: Building a Successful Native Plant Garden

Incorporating native plants into your garden is an investment that pays off in both ecological and economic terms. By enhancing your garden beds with these plants, you’re not just improving your own space – you’re making a meaningful contribution to the environment. Following the steps in this guide – evaluating your garden, preparing the soil, selecting native species suited to Maryland, and maintaining them with care – helps create a habitat that supports local wildlife and strengthens the resilience of your landscape.

The impact of native plants is undeniable. For example, native oak trees support over 500 species of caterpillars, while non-native ginkgos host only 5. Considering that raising a single brood of chickadees requires more than 6,000 caterpillars, the importance of native plants becomes clear^[1]. Achieving 70% native plant coverage in your garden ensures essential food sources for insects and birds across Maryland^[25]. Beyond supporting wildlife, native gardens are also more resource-efficient. They can use up to 85% less water than traditional landscapes^[26], cutting down on both water usage and costs. Plus, once established, native plants require little to no fertilizer or pesticides, saving you time and money while fostering a safer environment.

Though the results may take time to fully develop, the rewards are worth the wait. As native plants grow, their deep root systems help prevent erosion and limit stormwater runoff – an especially valuable trait during Maryland’s heavy rains and summer storms. Additionally, native plants are pollinator magnets, attracting butterflies and bees four times more often than non-native options^[2]. This increased activity not only enhances your garden’s beauty but also supports vital ecosystems.

Start small by gradually replacing invasive species and converting sections of lawn into native plant beds. Every new patch of habitat you establish contributes to a larger effort to protect Maryland’s native wildlife and address climate challenges. In fact, nature-based solutions like these can account for 30% of carbon sequestration needed to combat climate change^[27].

FAQs

How do I choose the right native plants for my garden’s unique conditions?

To pick the right native plants for your garden, start by assessing a few basics: soil type, sunlight conditions, moisture levels, and your local climate. These factors set the foundation for selecting plants that will naturally thrive in your space. Once you have a clear picture of your garden’s environment, dive into researching native species that align with these conditions. Focus on plants that are well-suited to your specific ecoregion and pay attention to their growth patterns, including size and spacing needs.

For a garden that’s both easier to maintain and healthier overall, group plants with similar needs for water, soil, and sunlight. This approach not only simplifies care but also encourages strong, sustainable growth. To get more region-specific advice, check out local gardening resources or native plant guides tailored to your area.

How does maintaining native plants differ from non-native plants in terms of watering, fertilizing, and pest control?

Native plants are perfectly suited to the local climate and soil conditions, making them far easier to care for than non-native species. Once they’ve taken root, they usually require very little watering, thanks to their deep root systems that help the soil hold onto moisture. Many native plants can also flourish without the use of fertilizers, relying instead on the natural nutrients already present in the soil or a bit of organic compost.

On top of that, native plants are naturally more resistant to local pests and diseases, which often means you can skip chemical pesticides altogether. Choosing native plants not only simplifies garden maintenance but also helps protect the environment and supports the local ecosystem.

How can I add native plants to my garden beds while managing invasive species?

To bring native plants into your garden beds while keeping invasive species in check, start by identifying and removing any invasive plants. You can tackle this with methods like hand-pulling, digging, or covering the area with cardboard or black plastic. These approaches help reduce soil disturbance and limit the spread of seeds. Make sure to dispose of all invasive plant material responsibly to prevent it from growing back.

Once the invasive plants are cleared, focus on preparing the soil for your native plants. Loosen the soil and, if necessary, enrich it with organic matter. Select native plants that match your region’s climate, soil type, and light conditions to ensure they thrive. Keep in mind that managing invasive plants is an ongoing process and may require several seasons of effort. With time, your native plants will take root and contribute to a healthier, more balanced garden.
