We strive to be your one stop landscaper - from initial design to project completion. We specialize in building custom landscapes that integrate every aspect of your outdoor environment and incorporate the unique characteristics of your home or building. We custom design every landscape to fit the needs of each individual customer and treat each project as an opportunity to achieve greatness. Nothing compliments a beautiful home like colorful planting beds, custom hardscapes, and soothing water features.

» Tree & Shrub Installation

We work with the best local nurseries to insure that our clients receive the highest quality plantings available. We custom design all planting jobs to incorporate balance, color, shape, and layout to make sure all landscapes are aesthetically pleasing yet completely functional. All plantings are hand chosen by Petersen landscaping and professionally installed with the necessary fertilizers, soils, and mulches.

» Tree & Shrub Care

Seasonal maintenance is imperative to ensure your plantings are healthy. We offer pruning services, fertilization, and mulching to keep your trees and shrubs healthy for years to come.

» Annuals & Perennials

The proper planting of annuals and perennials provides color, balance, and function throughout the entire growing season. We custom design each garden and planting bed to provide unique planting designs to ensure lush color in Spring, Summer, and Autumn. We work with our professional local nurseries to provide our customers the plantings available in the Keene area.

» Organic Fertilization

We offer our customers organic fertilization services to ensure our customers have a healthy environment in their landscape. Chemicals and pesticides are harmful for our customers, landscape plantings, and our environment in general.

» Privacy Plantings

Privacy trees and shrubs offer our customers a natural barrier from road sides, neighbors, or public areas. With the proper plant selections, privacy plantings offer an aesthetic value that is not achievable with artifical fencing materials.

» Mulching & Edging

Proper mulching both enhances the health of your plantings and adds color detail to the landscape. We spread all mulches with the proper fertilizers and edge details on every landscape project.

» Specialty Gardens

Custom plantings can set the mood in every landscape. We custom design every project to catch the mood of each individual property.
