Fall is the best time - specifically late August through mid-October. Lexington's cool-season grasses (bluegrass, fescue, ryegrass) recover most aggressively in fall when soil temperatures are still warm but air temperatures have dropped. Aerating in spring is a secondary option but less effective since grass must compete with weed germination for recovery nutrients.

A basic patio in Lexington typically runs $15,000-$25,000 installed, depending on size, material (concrete pavers vs. natural stone), and site prep. More complex projects - retaining walls, drainage, steps, or regrading - commonly reach $25,000-$50,000. Larger outdoor living spaces with multiple components, such as outdoor kitchens, typically fall in the $50,000-$100,000 range. These figures reflect 2026 Greater Boston labor and material costs.

Most Lexington landscapers begin spring cleanups and soil preparation in late March to early April, depending on frost depth and ground conditions. Planting typically starts mid-April through May. Popular companies fill their spring schedules quickly - it's best to book in February or early March to secure your spot.

Lexington falls in USDA Hardiness Zone 6b. Native plants that perform well here include mountain laurel, native azalea, switchgrass, coneflower, and New England aster. For trees, sugar maple, serviceberry, and American hornbeam handle Lexington's freeze-thaw cycles well. If you're near conservation land or wetlands, native and pollinator-friendly plantings are especially well-suited - several companies on this list specialize in that approach.

It depends on the scope. In Lexington, retaining walls over 4 feet typically require a building permit. Projects that alter drainage or are near wetlands may require Conservation Commission review under the Massachusetts Wetlands Protection Act - Lexington has significant conservation land, so this comes up often. If your property is near Lexington Center, Battle Green, or in a historic district, also check with the Historic Districts Commission before making exterior changes.

Landscape design fees in Lexington typically range from $1,500 to $5,000 for a residential design plan, depending on property size and project complexity. Design-build firms like Moodscapes often apply the design fee toward construction if you hire them for installation. Most offer a free initial consultation before proposing a design agreement.

A landscape designer creates a detailed plan for your outdoor space - assessing site conditions, specifying plants and materials, and producing drawings or renderings. A landscaper typically executes maintenance or installation work. Some companies do both (design-build). If you're starting from scratch or want a cohesive vision for your property, begin with a designer before hiring for installation.

Yes. Lexington has extensive protected conservation areas, and properties bordering wetlands or conservation land fall under the Massachusetts Wetlands Protection Act, which can require Conservation Commission review for grading, drainage changes, or construction near the buffer zone. Companies with ecological design experience - such as those specializing in native plantings, rain gardens, and stormwater management - are well-suited to navigate these requirements while creating a landscape that complements the natural surroundings.

Massachusetts requires a Home Improvement Contractor (HIC) registration for residential work over $1,000. You can verify a contractor's registration at mass.gov/hic. For pesticide application, look for a Massachusetts Commercial Pesticide Applicator license issued by the Department of Agricultural Resources. Always ask for proof of general liability and workers' compensation insurance before signing a contract.
