"We couldn't be happier with the work. From start to finish, the entire team was professional, responsive, and incredibly efficient. It was obvious from day one that he had years of experience—the quality of his work really speaks for itself. We actually hired them for three separate landscaping projects, each project was completed with great attention to detail. Communication was quick throughout the entire process, and they showed up when they said they would. If you're looking for a knowledgeable, reliable, and hardworking landscaping company, I would highly recommend them."

"Emerson saved my life and yard. I hired another Landscaper and he worked for me about a year and a half. One day on his own he decided to rip out my shrubs without asking and left gaping holes in my yard. Emerson came to my rescue and helped to get my yard back in shape. He is efficient, responsible and gave me a fair price. I would recommend Emerson Landscaping."

Landscaping FAQs, answered by experts

It is possible to DIY complete hardscaping projects, but in most cases, hiring a professional is best to get the job done correctly. Hardscaping—including installing patios, decks, retaining walls, walkways, and water features—is challenging and time-consuming, so the money you spend on a professional is typically worth it. Not only will the quality be better, but you could avoid problems that come along with a lack of hardscaping experience, like drainage issues that can lead to costly foundation damage and leaks in your home.

A full backyard renovation can cost between $15,000 and $50,000, depending on the scope of the project. Excavation, materials, and labor costs all contribute to the final cost of updating your outdoor spaces, and expensive features like a pool, a fence, or hardscaping carry a high price tag.

You should use mulch because it protects garden soil in a few key ways. This extra layer between the ground and the elements protects against erosion, helps your soil maintain moisture, regulates changes in temperature, adds nutrients as it decomposes, and keeps weeds at bay.

Landscape design can be a simple service that includes a drawing or visual representation of how your yard can be set up and optimized for your intended purposes. But it can also include all of the manual labor to make your vision a reality. When you speak with your landscape designer, ensure everyone understands the specific services you want. Some add-on services may include the following:

  • Sourcing and delivery of raw materials

  • Professional installation of features, including pergolas, decks, and pathways

  • Drainage system design

  • Recommendations for specific plants and trees

The best type of rock for landscaping depends on your specific project and needs, as different rocks are suited for different applications. For covering large areas or creating an affordable driveway, consider gravel, but note that it can wash away in flowing water. For water features, river rocks are a good option. Flagstone and cobblestone are ideal for aesthetically pleasing patios and walkways. If you are building a stone wall, fieldstone or small boulders are up to the task. Large boulders and landscape rocks work well as statement pieces, to fill empty space, or to indicate boundaries, but be mindful that they can overwhelm smaller gardens. The best approach is to first define your landscaping project and then select the rock type that best fits that purpose.
