Compare hundreds of trusted topsoil, mulch, and landscape-supply companies — from Manchester and Nashua to Concord, Portsmouth, and the Lakes Region — all in one place.
New Hampshire’s ground was shaped by glaciers, so it changes quickly from valley to mountain — and the right topsoil genuinely depends on where you are. Working with a nearby supplier who knows the local ground makes all the difference.
Most of the state’s native soil is acidic, stony glacial till over granite, with sandier loams in the river valleys and thin, rocky ground climbing into the White Mountains. The seacoast around Portsmouth mixes in sandier, better-drained soils.
Because winters are long and rainfall is steady, gardeners lean on screened topsoil and compost to build workable beds — and thick mulch and loam to establish lawns in a short growing season.
The products you’ll hear about most when you call New Hampshire suppliers.
Run through a screen to remove rocks and debris — the workhorse for grading and new lawns.
Topsoil cut with compost — the go-to for enriching beds and loosening tough native soil.
Layered on top to retain moisture and suppress weeds — essential during dry spells.
Sandy-to-loamy river-valley soils over glacial till are common. Screened topsoil and compost blends lead orders across the state’s most populated corridor.
Sandier, better-drained coastal soils define the region. Loam and compost-rich garden mixes are most-requested from Portsmouth to Dover and Rochester.
Stony glacial till and acidic loams surround the lakes. Screened topsoil and mulch are common from Concord to Laconia and Meredith.
Thin, rocky, acidic mountain soils are the norm. Imported topsoil and compost build plantable beds from Conway to Berlin and Littleton.
Bulk topsoil in New Hampshire runs toward the higher Northeast range, and prices climb in the rural north where hauling distances grow. Most suppliers sell by the cubic yard — one yard covers roughly 100 square feet at 3 inches deep — and many discount larger loads.
Everything you need to know about buying topsoil in New Hampshire
That’s typical for bulk screened topsoil; compost-rich garden blends run higher. Prices rise in the rural north, and many suppliers discount larger loads.
Glaciers left behind stony, compacted till across much of the state, so many projects start with imported screened topsoil. Compare local suppliers for clean, rock-free loam.
Working lime and compost into acidic ground helps most lawns and gardens. Many suppliers carry pre-blended topsoil sweetened for the region.
Demand peaks in spring and early summer once the ground thaws; the buying window is shorter than in warmer states.
Many deliver free within that range, then charge by the mile. North Country and mountain addresses may pay more for the longer haul.
