We work to be better stewards of our environment.

As a local leader in the landscaping industry, we have a critical responsibility to keep our city and waterways clean to protect the health, safety, and welfare of our communities, clients, and staff. It is our duty to ensure future generations have a habitat in which to live happily and prosper. For over 60 years, we have strived to stay up to date on evolving technology and techniques so we can offer efficient, environmentally responsible services and products, while still providing superior quality.


Our landscaping and maintenance crews use a premium, all-season fertilizer formulated from natural and organic ingredients that is OMRI Listed® for organic use. This fertilizer, along with other OMRI® options for plant health and disease control, can be used on operations that are certified organic under the USDA National Organic Program. Our garden centers also favor organic fertilizers by stocking and promoting them at each location.


Grass clippings and other yard debris have traditionally been bagged and hauled to landfills or yard waste processing centers. For more than 20 years, we have been recycling all organic yard debris. We also recycle and/or reuse paper, plastic, metal, batteries, oil, and other materials. We reuse all of our containers, reducing the need to purchase more and preventing them from being sent to the landfill.


Mulching grass clippings back into the soil profile is an essential aspect of environmental stewardship that requires special mulching decks and blades. Dennis’ 7 Dees is proud to partner with John Deere engineers to design improvements for maximum mulching in our sometimes challenging Pacific Northwest climate. Mulching creates a healthier, fuller lawn while reducing water and fertilizer use.


Choosing products that minimize our impact on the environment is very important to us. At Dennis’ 7 Dees, we maintain landscapes with the goal of reducing chemical use on plants and flowers. This includes integrated pest management, which takes advantage of all appropriate pest management options, including hand weeding and weed control through mulching.


We control runoff by installing water gardens, bioswales, wetlands, and eco roofs into our landscape designs. This protects our waterways and helps prevent water from overwhelming municipal utilities.


Working with major manufacturers, we provide the latest in products and technologies that use water efficiently, including water-saving nozzles, Rain Bird Smart Controller technology, and a grass seed blend requiring 75% less water than normal turf. Our commitment extends to the education and training of our crews.


We use fuel-efficient equipment for yard maintenance services with low-emission engines that prove to run cleaner than EPA standards for exhaust emissions.
