Best Time of Year for Landscaping Services in the Merrimack Valley

Timing matters when it comes to landscaping in New England. Homeowners across Lowell, Chelmsford, Tewksbury, and the rest of the Merrimack Valley get the best results by matching services to the right season. Here's a season-by-season breakdown.

Early Spring (March – April): Cleanup & Prep

As soon as the ground thaws, it's time for a spring cleanup — removing winter debris, dead growth, and salt damage along driveways. This is also the ideal window for dethatching and aerating your lawn before the growing season kicks in.

Late Spring (May – June): Planting Season

Once the risk of frost has passed, late spring is the best time to plant shrubs, perennials, and trees. It's also a great window to start a new patio or hardscaping project before summer heat arrives — see our patio design guide for ideas.

Summer (July – August): Maintenance Mode

Summer in the Merrimack Valley is about consistent mowing, watering, and weed control. It's not the best time for major planting due to heat stress, but it is a good window for mulching to help retain soil moisture.

Early Fall (September – October): The Second Planting Window

Many landscapers consider early fall the best time to plant in New England — cooler air temperatures paired with still-warm soil help roots establish before winter. This is also prime time for lawn aeration, overseeding, and fertilizing.

Late Fall (November): Final Cleanup

Before the ground freezes, a final fall cleanup — leaf removal, bed clearing, and winterizing irrigation — sets your property up for an easier spring. This is also when Lowell and Nashua homeowners should be locking in their seasonal snow removal contracts.

Pro tip: Booking your spring cleanup and seasonal snow contract at the same time each fall means one less thing to remember before winter hits.

Winter (December – February): Planning Season

While your yard rests, winter is the best time to plan next year's landscaping projects — patio builds, garden redesigns, or a new maintenance plan — so you're ready to book the moment spring arrives.
