Spring lawn care in the Twin Cities: protecting an established lawn
An established lawn has deep roots and a dense canopy, but a Minnesota winter still leaves it stressed. Snow mould, salt damage along sidewalks and compacted patches from foot traffic are common by the time the snow melts. Spring care is less about starting over and more about protecting what is already growing so it can thicken before summer heat arrives.
Start gently once the ground firms up
Walking on soggy turf compacts soil and tears crowns, so wait until the ground is firm underfoot. Then lightly rake matted areas to lift grass blades and improve airflow, which helps grey or pink snow-mould patches recover on their own in most cases. Rinse salt-burned edges with water to help flush the soil.
Mow high and feed modestly
- Mowing height: cool-season grasses common in the region, such as Kentucky bluegrass and fine fescues, generally do best kept around three inches or a little taller. Taller grass shades out weed seedlings.
- Fertiliser timing: many university extension services suggest that cool-season lawns benefit most from autumn feeding, with only a light spring application, if any. Heavy spring nitrogen can push leaf growth at the expense of roots.
- Weed control: pre-emergent products for crabgrass work only if applied before seeds germicate, usually as soil warms. Always follow the label, and remember they also stop grass seed from sprouting.
Look after yourself while you work
Yard work is real exercise. Warm up before raking or aerating, lift bags with your legs, wear gloves and eye protection, and wash up after handling fertilisers or herbicides. Spring pollen can trigger allergies, so check local pollen forecasts. If you notice persistent back pain, breathing trouble or skin reactions, talk to your own doctor.
