Organic Landscaping Services

We are Portland landscapers with a concern for the environment.

We recognize residential landscaping services as the original green industry. For us at Dennis’ 7 Dees, we know that sets the bar extremely high for protecting the environment. The entire community has a responsibility to keep our city and waterways clean and thriving. We strive to keep up to date on new and evolving technology and techniques to offer the best and most responsible choice of services and products.

As we work to be better stewards of the land we live on, Dennis’ 7 Dees is committed to continual improvements to reduce and recycle, while still providing our superior level of quality.

Responsible Landscaping Services

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.

Sustainable Landscape Maintenance
Mulching grass clippings back into the soil profile is an important aspect of environmental stewardship that requires special mulching decks and blades. Dennis’ 7 Dees has partnered with John Deere engineers to design improvements for maximum mulching in our challenging NW climate. Mulching creates a healthier lawn and reduces water and fertilizer use.


Recycling in the Portland Metro Area

Landscape Debris Recycling
Grass clippings and other landscape debris traditionally have been bagged and hauled to landfills or yard waste processing centers. For more than 20 years, we have been recycling all organic yard debris and are committed to continual improvements to reduce and recycle.

Recycling at Our Locations
All of our Portland metro landscaping locations recycle and re-use paper, plastic, metal, batteries, oil and other recyclables. We also reuse all of our containers, reducing the need to purchase more and preventing them from being sent to the landfill.


Energy Efficient Yard Maintenance Equipment

Choosing products that minimize our impact on the environment is extremely important to us. We use fuel-efficient equipment for all yard maintenance services, with proven low-emission engines that run cleaner than EPA standards for exhaust emissions.

We are beginning to connect our equipment to propane, which provides many benefits including more efficient and exceptionally safe fuel sourced from the USA that produces significantly lower amounts of some harmful emissions and increases energy security.


Landscapes Designed with an Environmental Focus

Landscapes Designed to Conserve Water in Portland, Oregon
Working with all major manufacturers, we provide the latest in products and technologies that use water efficiently, including water saving nozzles and Smart Controller technology by Rain Bird. Our commitment extends to the education and training of our crews.

We are using a new grass seed blend requiring 75% less water than normal turf. Its roots grow deeper, gathering water from a larger range, reducing its need for water.

Landscape Design Ideas to Reduce Runoff and Control Erosion
We’ve been controlling runoff for over 15 years by installing water gardens, bio-swales, wetlands and eco roofs into our landscape designs. This protects our waterways and helps prevent water from overwhelming municipal utilities.
