How to Prepare Roses for Winter in Michigan
Michigan’s winters can be brutal on roses, especially the more delicate varieties like hybrid teas and floribundas. But with a bit of fall preparation, your roses can emerge in spring healthy and ready to bloom. Here’s a step-by-step guide tailored for Michigan gardeners to help your roses survive and thrive through the cold months.
1. Stop Fertilizing Early
Cease fertilizing by Labor Day. Fertilizing too late in the season encourages tender new growth that won’t survive the frost. Instead, focus on strengthening existing canes by watering and mulching well.
2. Deep Water Before the Freeze
Roses need hydration to endure winter. Water deeply until the ground freezes, especially during dry autumns. Aim for about 2 gallons per plant per week, watering at the base to avoid fungal issues.
3. Prune Lightly
Avoid heavy pruning in fall. Trim only excessively long canes to prevent wind damage. Cut just above an outward-facing bud. Save major pruning for early spring when winter damage is visible.
4. Mulch and Mound
After the first hard frost:
Mound 8–12 inches of soil or compost around the base of each bush, especially over the graft union (the knobby part near the base).
Cover the mound with shredded leaves or bark mulch to insulate against freeze-thaw cycles.
5. Protect Tender Varieties
Hybrid teas, floribundas, and grandifloras need extra care:
Use rose cones (vented for airflow) or
Surround the plant with a wire cage and fill it with dry leaves. This shields against wind, sunburn, and animal damage.
6. Handle Climbing Roses Differently
Climbing roses are more exposed and need special treatment:
Detach canes from supports after the first frost.
Lay them gently on the ground and secure with stakes.
Cover with soil, burlap, and leaves to insulate them from sub-zero temperatures.
7. Clean Up the Area
Remove fallen leaves and debris to prevent overwintering pests and diseases. A tidy rose bed is a healthier one come spring.
Looking Ahead
Come spring, remove the mulch and soil gradually as temperatures warm. Prune away any dead canes (brown and brittle) and shape your roses for the growing season.
With these steps, your roses will be well-equipped to weather Michigan’s winter and burst back to life with vigor. Happy gardening!
