August through September is when you can actually set your yard up for long-term success.

Minnesota Garden Preparation for a Successful Spring

In Minnesota, the window between summer heat and the first frost is short, but it’s the perfect time to give your lawn and garden a boost that will pay off next year. Many homeowners focus on mowing and watering in the summer, but late August through September is when you can actually set your yard up for long-term success.

Aerate Your Lawn

Compacted soil from summer foot traffic can make it harder for grass roots to get the water and nutrients they need. Aerating now allows oxygen and moisture to penetrate deeper, encouraging stronger growth before winter dormancy.

Overseed Bare Spots

Cool-season grasses (like Kentucky bluegrass and fescue) thrive when seeded in late summer and early fall in Minnesota. Overseeding now means the seedlings have time to establish before the first frost, leading to a thicker, healthier lawn come spring.

Tidy Up and Mulch Garden Beds

Remove any dead or dying plants, then add a layer of mulch to help retain soil warmth as temperatures drop. This not only protects perennial roots but also reduces weed growth in the early spring.

Bonus Tip: Fertilize for the Future

A slow-release fall fertilizer feeds your lawn throughout autumn, storing nutrients in the roots so your grass bounces back faster after winter.

A little yard work in late summer can save you time and frustration next spring—and give you more weekends to enjoy Minnesota’s short but sweet fall season.
