How to Design a Native Plant Garden

One of the biggest criticisms of native plants is that they often look too wild, unkempt and messy.  Grasses dominate while wildflowers struggle to provide the visual impact desired in a landscape.  Wild is as wild does.

So how do we tame the wildness of the prairie? How do we design a native plant garden that doesn’t look so wild?  Is it even possible?  I believe it can be done.  You can have the beauty of the prairie and all the benefits of a native ecosystem with a properly designed native garden.

Consider these fundamentals as you design your native plant garden:

Match plants to your site. Look at your landscape.  Is it sunny or in the shade?  Is the soil clay or sand?  Evaluate these elements and choose plants that will thrive in the microclimate of your yard.  Sun-loving native plants need at least 6 hours of direct sunlight to grow happily. Otherwise look at more shade-loving natives.  A carefree landscape begins with matching plants with climate.  Choose plants that occur in the same or similar climate for a maintenance free garden.  It has been my experience that this is the most important element in developing a successful native garden.  Anytime you stray too far off, the plants don’t flourish and they require more effort.  Planting a swamp milkweed on a dry hill or a primrose in a bog will never work.

Design for succession of bloom. There are no Wave Petunias in the prairie or plants that bloom all season, so choose plants that will bloom in spring, summer and fall.  If you go to the prairie throughout the year, you will observe wildflowers coming into or out of bloom.  The prairie is constantly changing.  Design with those changes in mind.  Discover how native plants appear at different times of the year and highlight interesting elements such as seedheads for winter interest.  Grasses can be included for structure, winter texture and movement.   Little bluestem in fall accentuates the seedheads of the Missouri Black-eyed Susan beautifully.

 

Summer Prairie Garden

Group similar plants together. Fifteen blazing stars blooming in the summer create a focal point in the landscape.  Place them next to a spring blooming wildflower and a fall blooming wildflower and you have organized the display for year round interest.  Use grasses sparingly to frame the garden or as a backdrop for some of your wildflowers.  This makes it easier to maintain, because you know what is planted in each area.  When weeding, you know everything else has to be removed because wildflowers will reseed.

Keep your plants in scale. Choose plants that don’t grow taller than half the bed width.  So if your display bed is six feet wide choose plants that are no more than three feet tall.  A compass plant would be way too tall.

Define the space. A well-designed native garden can be enhanced with a border.  It can be edged with limestone, brick or some other natural material.  This element alone makes your native garden look clean, attractive, and intentional.  Even a clean-cut edge can really help define the garden’s borders.

Control Perennial Weeds. You will save yourself many headaches by eradicating problem weeds like bindweed and Bermuda grass before you plant.  It is better to wait until these weeds are eliminated before you establish your new garden, trust me!!!

It sounds so easy, but we all know that landscapes, no matter how well-designed, will take some input on our part.  Beautiful gardens don’t just happen. They are the result of planning, development, time and a little bit of effort.

I am still learning too.  My epiphany came several years ago after trying to grow dry, sun loving plants in a wet, sunny garden.  It took me three tries to realize the futility of my efforts.  Hopefully, you can learn from these basic principles and find success in your landscape.  If you need information about native plants, visit our plant library, landscape designs or give us a call.

 

Winter Dreams of Prairie Gardens

ThinkingMan2

We are near the longest nights of the year when your landscape is cold, brown, and sometimes snowy with few creatures stirring. But soon, if not already, you will be having visions of coneflowers and ground plums dancing in your head.

Since landscaping labor is not taking up your free time at the moment, now is the perfect time to be thinking about and planning the logistics of your spring or fall prairie garden.

Here are a few things you can be doing during the months of winter to prepare for your prairie garden:

Identify Desired Area

Identify the area you want to plant and measure the square footage. With a generally recommended planting rate of one plant/2-4 sq. ft., knowing your planting area will allow you to estimate the number of plants you need and help establish a budget (~$4/plant).

Install Edging

Edging around your prairie garden is not only aesthetically pleasing, but functionally critical to establish where you should stop weeding and start mowing. Garden center options include plastic, metal, wood, or brick, but my favorite is Kansas limestone. A good source in Central Kansas is the Florence Rock Quarry where I last acquired an inexpensive load for $20.50/ton.

Acquire Mulch

Mulch is essential to reduce water and nutrient competition for new prairie plants, reduce weeds, and slow soil moisture loss. Garden center mulch is always available in easy-to-transport bags but, you also have to pay for it. Many municipalities offer free self-serve mulch or a friendly request to a local tree-trimming contractor may get a pile delivered right to your desired location. A layer of newspaper under the mulch will give a bit more biodegradable weed protection in the first year.

Plan for Bermuda Grass Eradication

Believe me, you don’t want it in your prairie garden. If your site gets plenty of sun you most likely have it; delay your planting till late summer so you can eradicate this species during its growing season. This is the one scenario for which I use herbicide and plan for two to three glyphosate treatments (e.g., Roundup) in the months of June-September to eliminate this very difficult-to-weed warm-season grass.

Killing Bermuda grass is essential before planting.

Consider Sun Exposure and Other Notable Features

Sun exposure and notable features that affect soil moisture such as low spots or downspouts will affect your plant choices. Consider structures or tree canopies that will block sunlight anywhere from straight overhead to about 45 degrees off the southern horizon. Prairie plants can thrive with at least six hours of sunlight. With less sunlight you should consider more shade-tolerant woodland understory species. Water from downspouts will wash away mulch.

Pick Plants

Peruse our Dyck Arboretum plant library and keep an eye out for our spring and fall plant sale lists. Have fun choosing the plants that fit your preferences with regard to season of bloom, flower color, height, dormant season texture and color, wildlife attraction, and more. See our website for further tips and ideas on landscaping with native plants.

Attention to these items in advance will make your native landscaping endeavor much more successful and enjoyable. Enjoy your winter planning during the darkest days of winter and signs of spring will be here before you know it!
