Sustainable landscaping yields many benefits
There are many ways to make your landscape more sustainable, such as rain-barrels, planting in vertical layers, and mulching the soil. Sustainable landscaping can be beautiful, lower maintenance, and keep our waters healthier for people, fish, and other critters.
Pollution from common yard care products such as fertilizers and pesticides makes its way to our lakes, streams and other water ways.
Sustainable landscaping practices reduce common sources of pollution and restore soil health. Healthier soils not only help your landscape plants thrive, but they also help to keep our waters clean by absorbing and filtering rainwater.

The Magic of Soil
With simple practices, you can build and protect healthy topsoil that supports healthy plants and helps keep waterways clean.

Woody mulch helps to build healthy soils, saves water, and also keeps weeds at bay. To learn more about the benefits of woody mulch read:

Rain barrels and rain gardens can help keep polluting runoff from roofs & driveways out of our lakes and streams.

Vertical canopy layers such those created by trees and shrubs can be beautiful landscape features that also create great bird habitat.

Many sustainable landscaping practices can actually reduce your garden chores.
For example, you can nourish healthy soils by:
Leaving the leaves – decomposed leaf litter nourishes the soil,
Applying mulch – a 4” deep layer of woody mulch not only enhances soil health, it saves water and also suppresses weeds, and
Grass-cycling – instead of bagging and disposing of grass clippings, you can leave clippings on the lawn where they will supply some of your lawn’s nitrogen needs for free!
Note that if you live in the Lake Whatcom watershed, you’ll want to be extra careful to avoid adding nutrient pollution to the lake. For guidance on sustainable landscaping in the Lake Whatcom watershed and a great list of low-phosphorus mulch, compost, and soil products for your yard, look here: https://www.lakewhatcom.whatcomcounty.org/get-involved/at-home/gardening
And, with a little research, you can choose plants that are naturally pest resistant, plants that will thrive where you put them – in shade, or sun, or in lousy soils, drought-tolerant plants that will look good with less watering, plants that are the right size for your space and won’t need ongoing pruning work, and you can avoid noxious weeds and other invasive plants that might try to take over your garden.
