How do I choose the right topsoil for a NB landscaping project?

Choose a screened, loam-based topsoil with a balanced texture of sand, silt, and clay, ideally with 3-5% organic matter content, and always buy from a reputable NB supplier who can tell you the soil's origin and composition. At $35 to $60 per cubic yard delivered in the Fredericton and Moncton areas, topsoil is a significant investment for any landscaping project, and quality varies enormously between suppliers — cheap topsoil often comes loaded with weed seeds, clay clumps, rocks, or construction debris.

Screened topsoil has been passed through a mesh to remove rocks, roots, and large debris, producing a uniform, workable material. Ask for topsoil screened through a 1/2-inch or 3/4-inch screen — anything coarser may contain chunks that interfere with seeding and planting. The best NB topsoil suppliers offer a "garden blend" or "lawn mix" that combines screened loam with compost, typically at a 70/30 or 60/40 ratio. This blended product costs slightly more ($45-70 per yard) but saves you the trouble of mixing in amendments separately and provides a ready-to-plant growing medium.

When ordering topsoil in New Brunswick, consider the pH of the material. NB's native soils are acidic (pH 4.5-6.0), and topsoil sourced from local fields will likely share this acidity. If you are establishing a new lawn, request a soil test on the topsoil before spreading it, or ask the supplier for their test results. You may need to incorporate dolomitic lime at the time of spreading to bring the pH up to the 6.0-6.5 range that turf grass prefers. A soil test costs just $30-60 and can save you from spreading 6 inches of soil that needs heavy correction.

For lawn establishment, apply 4-6 inches of quality topsoil over graded subsoil, which requires approximately 5-10 cubic yards per 1,000 square feet. For garden beds, you may want 8-12 inches of depth, especially if the underlying soil is heavy Fredericton clay or rocky northern NB ground. For tree and shrub planting, use topsoil to backfill around root balls mixed with the native soil at a 50/50 ratio — using 100% imported topsoil in the planting hole can create a "bathtub effect" where water pools in the amended hole and drowns roots.

Order topsoil in spring or early fall for the best availability and pricing. Late spring and early summer are peak demand season in NB, and suppliers sometimes run low on quality screened material. Have the delivery dumped on a tarp or driveway rather than directly on existing lawn, as a pile of topsoil will kill grass underneath within days. Budget for delivery charges of $50-100 per load on top of the material cost, with most NB suppliers offering free delivery for orders over 10 cubic yards.
