How to Prepare Your Perennials for Winter
As the crisp fall air rolls in and the first frost threatens to turn your vibrant garden into a frosty wonderland, it’s time to think about preparing your perennials for the long Michigan winter. We know that Southeast Michigan’s unpredictable weather can take a toll on your plants, but with a few simple steps, you can help your perennials thrive and come back strong next spring.
Follow our expert tips to get your garden winter-ready—and if you need supplies, we’ve got you covered!
1. Wait for the First Hard Frost
Before you start cutting back or tidying up, it’s important to wait for the first hard frost—usually in late October to early November. This signals to your plants that it’s time to go into dormancy. Cutting back too early can encourage new growth that won’t survive the cold.
Once the frost arrives and turns those leaves crispy, it’s safe to begin your fall garden prep!
2. Cut Back with Care
Not all perennials should be cut down in the fall. For plants like peonies, phlox, and beebalm that are prone to disease, trimming them back to about 2–3 inches can help prevent pests from overwintering. But for plants like ornamental grasses, coneflowers, and sedum, consider leaving them standing. They not only provide beautiful winter interest but also offer food and shelter for birds.

3. Clear Debris and Weeds
Cleaning up weeds and fallen plant debris is an important step in preventing pests and disease from making your garden their winter home. Healthy plant material can go into the compost, but be sure to toss any disease-ridden parts.
4. Divide and Transplant (If Needed)
Fall is a great time to divide overgrown perennials like hostas, daylilies, and irises. This gives your plants a chance to establish their roots before the cold sets in. But be quick—if the ground has already started to freeze, it might be too late!
5. Protect with Mulch
Once the ground begins to freeze, it’s time to apply a 2–4 inch layer of mulch around your plants. This simple step helps prevent freeze-thaw cycles, keeps moisture consistent, and provides insulation for tender roots.
Looking for mulch or compost? We offer high-quality, locally sourced mulch to protect your plants and keep your garden healthy through the winter.
6. Water Well Before the Freeze
Dry fall weather can leave your perennials parched. Be sure to give them a deep watering before the ground freezes. Moist soil holds more heat and helps protect plant roots during the colder months.
7. Extra Protection for Tender Perennials
Some plants, like lavender or newly planted perennials, may need a little extra protection from the winter chill. Consider adding a thicker mulch layer or even covering them with evergreen boughs or burlap for added warmth.

8. Leave Some Plants for Wildlife
Did you know that many of your perennials, like echinacea and rudbeckia, can provide food and shelter for birds during the winter? By leaving some of these plants standing, you’re helping local wildlife survive the cold months. Plus, it looks beautiful when covered in snow!
9. Mark Your Plants for Spring
Winter in Michigan can be tough to navigate, but you don’t want to forget where your plants are! Use weatherproof markers or small garden stakes to mark key areas in your garden. This way, you won’t accidentally disturb your plants during spring cleanup.
