"THE BEST LANDSCAPE SERVICES IN THE PORTLAND AREA. Iâ ve used Nelson Mendoza on all of my landscaping projects since I discovered him. Most recently , Nelson solved all of the yard problems at my Portland residential remodel. This was a big project - Removed huge areas of eroded, weed covered soil; re-graded large areas for drainage and erosion control; prepped for mulch and ground cover; planted 125â of hedge shrubs. He also dug out stubborn old hedge stumps, and offered ideas and solutions for landscape and hardscape areas i need to address in the near future. Nelson was a pleasure to work with! Heâ s extremely professional, reliable, and hardworking. Has a wonderful â can-doâ attitude. Very fair rates and quick responses. I also know that Nelson Mendoza provides the highest quality yard maintenance services. If youâ re looking for the best, you should call Nelson Mendoza Landscaping."
