An “eco-friendly” garden or landscape is really just about working with nature, not against it! In fact, you may already incorporate eco-friendly practices into your garden without even knowing it. Read on and see, then consider these ten ways to create an eco-friendly garden.

The term “eco-“ in the phrase “eco-friendly garden” refers to “ecology”—the interactions between organisms and their environment. Such a garden or landscape is one that is designed with nature and the environment in mind. You may also know the practice as “environmentally friendly” or “sustainable gardening.”

1. Choose the proper plants.

The eco-friendly rule of thumb is to go native! Plants that already fit your climate will thrive with less care and stress. They’ll support the health of your entire yard, too, attracting pollinators and beneficial bugs. Non-native, invasive plants often wipe out native species which harms the entire ecosystem.

In general, group plants that have similar needs: Put shade lovers together, heavy drinkers together, pH partners together, and sandy vs. loamy soil seekers together. Match plants and conditions and think of your property as having different zones. The results will save you time, effort, and replacement expense.

For example, lavender enjoys dry, sandy soil and full sun; avoid planting lavender next to elephant’s ear which loves moist soil and shade!

Read “Why Native Plants Matter” with a list of common native plants.


2.  Welcome pollinators and friendly bugs that eat pests 

Pollinators—from bees to butterflies—are vital to our flowers and food. In fact, about one-third of every bite of food comes from pollinators!

  • Having native plants and reducing pesticides are two big ways to encourage pollinators in the garden. See plants that attract butterflies.
  • Bees are the most important pollinators in most ecosystems. Are you familiar with native bees? They are small, solitary bees such as Mason bees which are responsible for most pollination. (Honeybees are not native.) Native bees support sustainable native plant and pollinator communities. Read more about native bees, the best pollinators around


Other insects—wasps, flies, ladybugs, and beetles—are beneficial to plants for pest elimination. For example, lacewings and ladybugs eat aphids which destroy crops.

Note: You don’t need (or want) to “buy” native bees or these “good” bugs. It’s better that they are local.  By providing native plants and the right habitat, they will come to you!

A garden with diversified sources of nectar (e.g., shrubs, trees, and flowers—ideally, natives) that bloom from early spring through late fall can attract insects and ultimately benefit the entire garden. For example, bright flowers such as sunflowers, candytuft, and marigolds create places where ladybugs nd lacewings can shelter and lay eggs.

Read “Beneficial Insects in the Garden” and see a list of the good bugs with pictures!


3. Encourage birds.

A healthy ecosystem invites a wide variety of wildlife into it. Many of your feathered friends will snatch up slugs, snails, grubs, caterpillars and other pests that destroy plants.

  • Select native plants that attract the kind of insects, berries, and seeds that birds eat. Learn more about creating a bird-friendly backyard.
  • Put up bird feeders and nesting boxes (including those you have made) to encourage more to visit. See how to choose a bird feeder.
  • Birds also need water. Install or make a birdbath for them! It should be shallow (1 to 1.5 inches deep) and contain a few small stones or pebbles for birds to rest on.


4. Be water-wise

Using water thoughtfully is a very important part of an eco-friendly landscape—and makes garden and yard so much easier to manage! Here are tips:

  • As advised above, select your plants with care! If you have a dry area, consider plants that are more naturally drought-tolerant such as lavender, sedum, Dianthus (“pinks”), and speedwell (Veronica). If you have a wet area, consider water-tolerant plants (that don’t mind wet feet) such as perennial iris, canna, and elephant’s ear and cinnamon, marsh, and holly ferns.
  • In terms of irrigation, sprinklers waste quite a bit of water; at minimum, use sprinklers that have timers. Of course, vegetable and flowers gardens should not be sprayed from overhead; this is an easy way to encourage disease. Use a watering hose and water directly at the soil level. Even better: For gardens, flower beds, trees, and other non-lawn areas, installing a drip irrigation system which puts the water right into the soil, right where you want it.
  • Harvest your rain water! A rain garden is a shallow, depressed area in your landscape with highly permeable (not hard) soil. This spot collects rain water from a roof, driveway or street and allows it to soak into the ground. Planted with grasses and flowering perennials, rain gardens can be a cost effective and beautiful way to reduce runoff from your property. Rain gardens can also help filter out pollutants in runoff and provide food and shelter for butterflies, song birds and other wildlife. See a “sun” and a “shade” rain garden plot plan.

  • Alternatively, install a rain barrel to catch water and use it on your plants. See our post about rain barrels.
  • Mulch it!  Mulch such as compost slows water down, so that more moisture goes into the soil instead of running off. Water does not evaporate from the soil surface as quickly. Mulch provides nutrients to the soil and helps suppress weeds. Mulch can be applied three inches thick in existing ornamental beds, but don’t pile it to close to tree trunks or the base of plants. Read more about the “Benefits of Mulch.”
  • Finally, consider reducing the size of the lawn. Can some of your lawn be converted to a wildflower meadow. Look into the newer low-water use grasses to see if they will flourish in your climate.

5. Plant companions

With companion planting, certain plants are grown near each other improve each other’s health and yields. Usually, companion plants help ward off pests. For example, dill and basil planted among tomatoes can protect from tomato hornworms.

Also, mix flowers and vegetables together! You don’t have to choose between ornamentals and edibles. Many types of flowers confuse the “bad” pests and help you grow a healthier garden.

Learn more about companion planting.


6. Avoid harmful chemicals

All gardens have some pests, but deter them in ways that won’t harm the food you are growing!

For example, slugs and snails can really chow down on lettuce. However, instead of spraying with chemicals, create barriers such as crushed eggshells which these soft-bodies pests will avoid. Put a band of petroleum jelly around containers because these pests won’t be able to climb up. Another favorite tactic: Put tuna tins filled with beer into the ground; slugs love beer! See our Slug pest page.

From Diatomaceous Earth to Neem Oil, there are many less toxic methods now that really work. Remember that chemical fertilizers run into rivers, oceans and wetlands. Pesticides and herbicides tend to kill many more creatures than the one or two bugs, as annoying as they might be.

7. Try composting

Do you have room in the corner of your yard? Instead of throwing out kitchen-based scraps and yard trimmings, dispose of them in a compost pile You’ll encourage compost-making worms and bugs which will help create a rich, fertile soil for your garden within months. It’s a great way to use fallen leaves, too! 

  • We have the perfect compost recipe to get things cooking. See how to compost!
  • There’s also in-garden or in-situ composting which when you are composting directly where you’re going to grow. See more about in-garden composting.
  • Ever heard of vermicomposting? Just have worms eat your garbage! It’s an easy way to recycle food waste indoors year round. See how to vermipost.
  • If you have roses or ornamental gardens, consider “compost tea” which is a natural fertilizer to help plants thrive. See how to make compost tea.


8. Avoid being wasteful

In general, caring about yourself and nature means being less wasteful with Earth’s resources. For example:

Buy in bulk when you know you’ll need a lot of topsoil, mulch, compost, or other materials. Ths cuts down on plastic bags. Many garden centers will even deliver right to your yard.

Reuse, recycle, or return old plastic pots and trays. See six ways to reuse pots and containers.

In fact, you could even make your own plant pots! See how to make biodegradable plant pots.


9. Give grass a chance.

If you’re going to grow grass, eliminate the chemical pesticides you spread on lawns in favor of alternatives that are healthier—healthier for you, for the lawn, and for the environment.

  • Start by checking your lawn’s pH (acidity) with a test kit available at most nursery and garden supply stores. Soil pH affects the ability of plants to absorb nutrients. Spread limestone to raise the pH level; spread aluminum sulfate to decrease the pH level.
  • Grow grass that is suitable to your needs, not just in terms of climate and soil, but also purpose. Ask your nursery to recommend seed for grass that suits your site.
  • Don’t shave the lawn; mow it to be 2.5 to 3.5 inches tall all season. Cut it to about 2 inches in autumn.
  • Water about 1 inch per week and always in the morning; place a measuring cup among the blades to gauge the amount of water used.
  • And, if at all possible, use a hand mower, instead of an electric or gas model. You’ll appreciate the freedom from fumes and noise and perhaps sleep more soundly after walking your property.

10. Buy good garden tools

We’re frugal at The Old Farmer’s Almanac but let’s not be penny-wise and pound-foolish. For example, forget about the $1 garden hose. It’s probably going to break quickly and just become another item to throw out. Vinyl hoses are generally the least expensive but have the shortest lifespan. Rubber hoses are more expensive, but tougher, more flexible, and last longer. Also, get a brass coupling, not plastic, to cut down on leaks!


Go for quality over quantity. Do you really need to purchase every tool for every landscape use? If you use a tiller once a year, consider borrowing a neighbor’s tiller. If you have your own set of tools, lend the weed-eater out twice a year.

Also, if you have time, stop at garage sales and thrift stores. It’s amazing how many garden tools are just sitting in someone’s garage and usually the older tools are better crafted than the new ones! If you have your own tools just sitting around and unused, donate them to a neighbor or thrift shop!

We hope these eco-friendly ideas help you create a more natural, low-maintenance garden and landscape. We welcome your comments, too.

Slugs and eggshells

Great article regarding "10 Tips for an Eco-Friendly Garden". However egg shells do not deter slugs. This seems to be more of a myth that a fact. gardenmyths.com/eggshells-control-slugs/
