Bringing nature home is easy with [email protected], which is an environmentally responsible land stewardship support program for homeowners. There are some simple concepts that every property owner in the [email protected] program incorporates into his or her landscape. If you think you have a good handle on these topics, click here to get to work on certifying your property. Otherwise, read-on for some information to help get you started.
One of the most important steps you can take is to add plants to your landscape that are native to northeastern Illinois. Nothing helps soil, water or ecosystems like natives. You’ll be delighted with the profusion of trees, shrubs, perennials and grasses to choose from, and many work well in designs ranging from formal to casual.
Native plants evolved under this climate with these soils – so they’re hardy and require little in the way of watering or fertilizing. And because they evolved here, they’re generally in balance with local food chains.
Native plants tend to have deep roots that build rich soil. Those roots aid in both water purification and rainwater absorption. And they provide essential food chain links – many of which have become broken but are good candidates for repair. Songbirds and butterflies will become regular visitors.
Keep the lilacs, peonies and daffodils. There’s no need to remove your beautiful garden plantings. Instead, pick a spot or two where you can add a native tree, install a new perennial garden or beef up an existing one. Line a fence with native roses. Plant a gorgeous spicebush outside your kitchen window. Shade your entry way with a noble oak. We suspect every property has some room for nature.
Some people think native plants look good only when used in cottage gardens or natural landscaping. Think again. More and more people are incorporating natives into formal and semi-formal designs. Design elements tend to include such considerations as symmetry, low-growing species and stiff plant structures. Designers may also create a palette that features a smaller number of species presented in groups of massed plantings. Another technique is to edge garden beds with hardscaping or a cut-edge lawn. And a well-placed bench, arbor or other garden accessory always adds to a lovely aesthetic.
There’s a small set of plants – super species if you will – that did not evolve here and are causing serious, expensive problems now that they’ve arrived. Buckthorn, garlic mustard and teasel are examples. Featuring longer-than-normal growing seasons, astounding reproductive abilities and low disease resistance, they enter our treasured natural areas and take over. As a result, dozens of native plant species – and the wildlife that depend upon them – disappear. Many other aspects of ecosystem health can suffer as well, including soil chemistry, hydrology, structure and resilience. You can make a huge contribution to this issue by finding and removing invasive species lurking on your property.

Here’s the problem: birds oftentimes eat berries on one property and eliminate the seeds on others. You may not see this because a flock of birds frequently arrives for just a short period and picks the place clean. By the way, buckthorn berries are diuretics, causing those poor birds to lose a great deal of fluids and nutrients. So we can’t assume these berry-producers are good for nature.
Some invasives show up uninvited but others are inadvertently purchased, planted and lovingly cared for as beautiful elements of your landscape. Barberry and burning bush are examples. They’re hardy and disease-resistant, just what we look for in landscape choices. But that’s exactly what makes them more likely to hop the garden fence and invade the nearest nature preserve. The garden center industry is becoming aware of problems posed by invasive species – some outlets faster than others – and making healthy changes.
In the past, species were restricted to certain areas by such barriers as oceans, deserts and mountain ranges. Now virtually all such obstacles have been breached and people are joined in our transcontinental travels by all sorts of species – both intentionally and not. This worldwide shake-up has exposed vulnerable ecosystems everywhere to a handful of botanical bullies that displace natives and upend ecological processes.
Traditional landscapes do not give our native birds and butterflies what they need in the way of food. The typical plants we choose for our yards like grass, hostas, daylilies, boxwoods, roses, vinca and most of the traditional favorites are foreign plants to our wildlife. Our native wildlife needs the berries and bugs that thrive on native plants. The native plants of our region have evolved in this area for over 10,000 years. The bugs and berries that grow on native plants are the day to day food source that sustains our bird population. All the birds of our region rely on bugs for protein. The bugs live in and on the native plantings. The ecosystem in our region is based on plant life. All the creatures here need the native plants, insects, moles/voles as a base for their diet. All birds in our region, including those above as well as cardinals, blue jays, wrens and warblers, need insects and berries every day to survive. By changing our landscape to plants that will host beneficial insects we encourage these beautiful birds to come feast in our yards. If you don’t see these birds often – it may be that you have nothing of interest for them…
A butterfly garden is an easy way to attract the many species of butterflies common to the Chicagoland area. These colorful gardens are full of native, nectar-rich plants that provide food for butterfly larvae and adults. They can be large or small, and adapted to almost any soil conditions, so get planting, and watch the beautiful critters appear!
Butterfly gardens are easy to construct, require little water once established, and need no fertilizers. Here are some tips to keep in mind:

When it rains outside or the spring thaw arrives, the resulting water needs to go somewhere, and in days gone by, most of it soaked into the ground. But today that option is frequently cut off by buildings, parking lots, streets and even heavily compacted lawns. So the water gets channeled – quickly – into streets, sewers and pipes where it’s whisked off to the nearest wetland, lake or stream. The streams can hold only so much before spilling their banks, which is a part of why we see more flooding these days.
Up for a little adventure? Literally follow your water. Wait for a good storm, and then pull on your rain boots and go. Bring some kids along!
Ironically, in many parts of the world, rainwater would be viewed as a precious gift rather than something to be rid of. It would be collected and used. And indeed, many Americans are starting to take this view. Rain barrels and cisterns placed at the base of downspouts provide free water – free! – for watering gardens, washing cars and cleaning tools. Check out TLC’s rain barrel sale.
As rainwater leaves your property and flows toward the nearest lake or creek, you may wonder how it fared while on your watch. Did it pick up any fertilizers or other lawn chemicals along the way? Did it cross any bare soil where it became muddy? Fertilizers lead to algae and weed problems. Other lawn products bathe fish eggs, frog eggs and other aquatic life in a toxic solution of unhealthy chemicals. And muddy water lowers oxygen levels, smothers eggs and makes it difficult for turtles, frogs and larger fish to hunt their prey.
Given the national surge of interest in healthy living and sustainability, it’s no wonder people are re-thinking their lawns. Lawns consume enormous quantities of time, money, water and chemicals. We hear from many people who are concerned about the health risks posed to children and pets from lawn care chemicals that are commonly used in the U.S. but banned in much of Canada. People also have a growing awareness about the impact of lawn chemicals on clean water and healthy lakes and streams. Every week during the growing season, Americans have been mowing, watering, fertilizing and raking the equivalent of Wisconsin! What’s a suburban homeowner to do? Here are some ideas to consider.
The first question worth pondering is, how large of a lawn do you need? Many people are surprised when then realize how much of their lawn is decorative – and an expensive decoration at that. You might prefer to replace some turf grass with beds of native groundcovers, shrubs, trees, or perennials. Studies show that residential properties with well-designed beds of native trees and shrubs add significantly to the property value. After making the initial investment, you’ll save time and money on lawn care while supporting clean water, rich soil and resilient ecosystems. Be sure to choose something that works for you – if you’re not a gardener, trees and shrubs set within mulched beds can make a beautiful statement while providing songbirds and butterflies with much-needed habitat. Their autumn leaves serve as great mulch and fertilizer.
Is the guy in the radio ad making you feel obligated to apply chemicals to your lawn every few weeks? Weed-and-feed programs are expensive, short-lived approaches to lawn care, and present health concerns for children and pets. One easy step everyone can take is to reduce the number of treatments or the application rate. You’ll probably be pleasantly surprised at the results. Another good trick is to leave the lowest one-third of the property untreated – rain will wash the chemicals from the treated area into the untreated area as it flows off your property. Another idea is to create a bed of native plants (trees, shrubs or perennials) at the lowest portion of your property – where the rainwater exits. This bed will capture and infiltrate many impurities before the water leaves on its way to the local pond or stream.
Raise your mower to three or more inches and you’ll grow healthier grass with longer roots. Thus it will better survive droughts and shade out many weeds, too. Leave your clippings on the lawn where they can break down and return nutrients to the soil. A sharp mower blade delivers a clean cut, which creates healthier grass. And when the peak of summer arrives, it’s easier on your lawn to let it go dormant rather than trying to keep it green with frequent watering. A dormant lawn doesn’t have to be mowed, so it saves you time and energy. Lastly, if you do water, do it in the morning – not evening – to prevent fungus issues.
A more holistic approach to lawn care is to create a lawn that’s able to deliver its own nutrients and pest control. It’s not hard – the answer lies in healthy soil. Aerate your lawn intensely in summer with a core aerator – the kind that pulls up plugs of dirt. Then spread a quarter-inch layer of compost. Beneficial micro-organisms will return and within several years they will flourish in what was formerly dead soil. Also, your grass will be able to grow stronger roots in the formerly hard and compacted soil.
If you use chemicals, it’s less expensive, more effective and healthier all around to treat a specific weed rather than the whole lawn. Also, dandelion tools have come a long way since we were all kids.
See the section on compost, above.
Would you prefer to mow once a month rather than once a week? You’ll save both time and money. If renovation or construction requires you to seed a new area altogether – and you’ve decided lawn is a better solution for this particular spot than beds of low-maintenance native plants – then consider low-mow fescue grass or no-mow buffalo grass. Because these are slow growing, you need a weed-free soil to start with and/or serious weed control while your new turf is getting established. Also understand that in spring, buffalo grass won’t turn from brown to green until warm weather is fairly constant, unlike most lawns that green-up in early spring.
Another option is to simply embrace a lawn that is a collection of myriad short green plants that includes grass as well as uninvited species. Mow high and call it a day. If you take this approach, please consider an occasional aeration to keep your soil from becoming compacted. Compaction leads to dense, lifeless soil that does not easily absorb rainwater. Also, if you embrace the dandelions and other species making their home in your lawn – but your neighbors do not – explore the idea of hedges or shrub beds on the property line to prevent weed seeds from blowing next door and provide a visual barrier. It’s nice to get along with the neighbors even if approaches to lawn care aren’t quite the same.
