How do I repair lawn damage caused by snow removal in NB spring?

Wait until mid-April or later to begin repairing snow removal damage to your New Brunswick lawn — the ground must be firm enough to walk on without sinking before any repair work will be effective. Working on soggy spring soil compacts it further, making recovery slower rather than faster. Once the ground is firm and you can see the full extent of damage from plowing, shoveling, and salt exposure, begin a systematic repair process.

Start with a thorough assessment of the damage types. Plow scrapes and gouges are the most common — these are areas where the plow blade dug into turf, tearing up grass and soil. Salt damage shows as brown, dead strips along driveway and walkway edges where de-icer runoff concentrated. Compaction damage appears as thin, struggling grass in areas where snow was piled all winter. Each type requires a slightly different repair approach, and most NB properties have all three after a typical 250-300 cm snow season.

For plow scrapes and gouges, the repair process is straightforward. Rake out loose debris and torn turf from the damaged area. If the soil has been scraped away, add topsoil to bring the area level with the surrounding lawn — you'll typically need 1-2 inches of soil for shallow scrapes and up to 4-6 inches for deep gouges. Firm the soil by tamping with your foot or a hand tamper, then overseed with a grass seed mix suited to NB's climate (Kentucky bluegrass and perennial ryegrass blends work well). Cover the seed lightly with a thin layer of topsoil or peat moss, and keep it consistently moist for 2-3 weeks.

For salt-damaged areas, soil treatment comes before reseeding. Flush the affected areas with generous amounts of clean water — apply 2 inches at a time, let it drain, and repeat 2-3 times over a week. This leaches sodium below the root zone. Follow with an application of gypsum (calcium sulfate) at 20-40 lbs per 1,000 square feet, which chemically displaces sodium from the soil. Wait 2-3 weeks after gypsum application before seeding, as the soil chemistry needs time to stabilize. NB's spring rains often help the flushing process along naturally.

For compaction under snow pile locations, core aeration is the best remedy. Rent a core aerator ($50-80 per day from NB equipment rental shops) and make two passes over the compacted areas in perpendicular directions. The plugs of soil pulled out create channels for air, water, and nutrients to reach the root zone. Follow aeration with a light topdressing of compost and overseeding.

Timing matters for seed success. Address structural repairs (filling gouges, flushing salt) as soon as the ground firms up in April, but save overseeding for the optimal mid-August to early September window when soil is warm and weed competition is low. Budget $100-300 for DIY repairs on a typical NB property, or $200-500 for professional spring lawn restoration.
