Winter’s icy breath can be harsh, especially in the Land of 10,000 Lakes. As Minnesota’s gardeners know, protecting perennials from frost is vital to ensure these cherished plants return in full splendor come spring. Check out the tips we gathered to help your perennials brave the frosty months.
Select Hardy Perennials
Choosing cold-hardy perennials well-suited to Minnesota’s climate is the first line of defense. Options like coneflowers, black-eyed Susans, and asters are stalwart in the face of frost. Applewood Nursery & Landscaping can suggest a plethora of frost tolerance for your zone.
Know Your Frost Dates For Your Zone
Keep an eye on the frost dates in your region. The average last spring frost and first fall frost dates vary across Minnesota, from late April to mid-October. Plan your gardening schedule accordingly.
Late-Season Pruning
Prune your perennials in late autumn to remove any dead or diseased growth. This ensures healthy regrowth in the spring.
Mulching for Insulation
A blanket of mulch around the base of your perennials is a champion against frost. Apply it once the ground has frozen in late fall. A 2- to 4-inch layer will help maintain consistent soil temperatures and shield roots from severe cold.

Water Well Before The First Frost
A well-hydrated perennial is more resilient to frost. Deeply water your plants before the ground freezes to ensure they have adequate moisture to sustain them through the winter.
Wind Protection
Minnesota’s gusty winds can exacerbate frost damage. Install windbreaks or plant perennials near natural windbreaks to reduce the impact of icy winds.
Covering Up
For early and unexpected frosts, use frost cloth or old bedsheets to cover your perennials at night. Remove the covers during the day to allow sunlight and air circulation.
Indoor Overwintering
For especially delicate perennials or potted plants, consider overwintering them indoors. A cool, dark, and well-ventilated location can protect them from the worst of winter’s chill.
Minimize Fertilization
In late summer, halt fertilization to prevent tender new growth that can be susceptible to frost damage. This allows perennials to naturally prepare for winter, entering a state of readiness for the colder months.
Observe and Tend
Regularly check your perennials during the winter months. Remove any heavy snow accumulation that could weigh down and damage the plants. Remember to assess overall plant health, provide adequate moisture, and remove spent flowers and diseased foliage. Proper late summer care helps ensure the resilience of your perennials during the approaching frosty season.
