How deep should I put topsoil down for a new lawn in Keene?

For establishing a new lawn in Keene, a minimum of 4 inches of quality topsoil over the glacial till base gives grass roots enough loose, nutrient-rich material to establish before hitting the compacted layer below. Six inches is even better on properties with slopes or areas prone to frost heave, which is common in Zone 5b through the winter and early spring.

When should I do my soil work in Keene to be ready for planting season?

The best window for major soil projects in Keene is mid to late May, after the ground is fully thawed and dried out from spring rains, and just before the May 27 last frost date passes. This gives you time to spread, grade, and let the soil settle slightly before you seed or plant, and the warm late-May temperatures help new plantings establish quickly once they go in.

My Keene backyard has low spots that flood after heavy rain. Will topsoil help?

Low spots on Keene properties are common because glacial till's poor drainage creates depressions that collect water after rain events. Filling with quality topsoil and grading the area to direct water away from the low point is an effective solution. Pairing new topsoil with a stone drainage channel or dry creek bed can handle the flow during Keene's heavier rain events without eroding the filled area.

What is the difference between topsoil and garden soil for Keene raised beds?

Topsoil is a general-purpose growing medium good for lawns, grading, and filling. Garden soil is a blended product with higher organic matter content, better aeration, and often added compost, making it better suited for vegetable and flower production in raised beds. Given that Keene's native glacial till is already low in organic matter, raised beds filled with a quality garden soil blend give vegetables and perennials the nutrient-rich, well-drained environment they need to thrive through a Zone 5b growing season.

How much topsoil do I need for a 10 by 20 foot garden bed in Keene?

A 10 by 20 foot bed at 6 inches deep requires about 3.7 cubic yards of soil. Our calculator on this page will walk you through the exact math for any dimensions and depth. For raised beds in Keene where you are building up above the glacial till rather than tilling into it, the full depth of the bed needs to be filled with quality material since you cannot rely on the native soil below.

Is bulk delivered topsoil screened and ready to use, or will it have rocks in it like Keene's native soil?

Our screened topsoil is processed to remove large rocks and debris before delivery, which is especially important in the Keene area where native soils are notoriously rocky due to the glacial till parent material. You may find occasional small stones in any natural topsoil product, but it will not have the large embedded rocks that make working with native Keene soil so frustrating.
