Your Local, Family Owned, & Sustainable Portland Landscaping Business

Dennis’ 7 Dees is a local, family-owned and operated business with over 60 years in the industry. 

In addition to providing the best customer service to our clients, it’s important to us to be the best stewards of our environment that we can. A local leader aware of the responsibility we have, we take numerous steps to protect the welfare of our community so you can feel good about choosing us for sustainable Portland metro area landscaping:

  • We recycle all organic yard debris, reuse all of our containers, and recycle/reuse metal, paper, batteries, plastic, oil, and other materials. 

  • Crews use a premium fertilizer which is all-season and made from natural and organic ingredients and each of our garden centers favors organic fertilizers. 

  • Our products are chosen to have minimal environmental impact. We aim to reduce chemical use on plants and flowers partly through measures like hand weeding and weed control through mulching. 

  • Dennis’ 7 Dees uses energy-efficient equipment for yard maintenance services – in fact, our low-emission engines run cleaner than EPA exhaust emissions standards. 

  • To control runoff, protect waterways, and prevent overwhelming municipal utilities, we incorporate and install bioswales, water gardens, wetlands, and eco roofs into our landscape designs. 

  • In the same vein, we care about water conservation and utilize the latest technologies to ensure water is used efficiently, such as with water-saving nozzles and a grass seed blend which requires 75% less water than normal turf.
