With the arrival of fall in the northern Great Plains, gardeners are enjoying the season's beauty but must also prepare for the impending winter. Tender roses, such as hybrid teas, floribundas, and grandifloras, require special care to survive the cold as they are bred for milder climates.
One traditional method, the styrofoam cone, is falling out of favor due to its drawbacks. It can trap moisture, leading to rot, and fluctuate temperatures on sunny days, potentially waking the plants prematurely and increasing the risk of winter damage. Moreover, these cones are not visually appealing and can become dislodged by strong winds.
A more reliable approach involves using well-drained compost. By piling about 10 to 12 inches of compost over the rose's base after the plant has gone dormant from hard freezes, gardeners can provide effective insulation.
Once the compost has frozen, adding another layer of leaves or straw contained within a chicken wire cage can further protect the plant. Prior to this, applying a fungicide on the canes helps prevent rotting during the cold months.
Another highly effective technique is the Minnesota tip method, originating from Minnesota's rigorous winter conditions. This method includes tying the rose canes together, applying fungicide, and then carefully tipping the plant into a pre-dug trench beside it. This method ensures only the roots bend, minimizing plant stress.
After covering the trench with soil and allowing it to freeze, an additional protective layer of straw or leaves is added.
For those seeking a low-maintenance solution, planting hardy shrub roses like the Canadian Artist Series can be ideal. These roses are bred to withstand winter without the need for elaborate protection. Cultivars such as Campfire and Emily Carr not only survive cold climates but also add vibrant colors to the garden with minimal effort.
By choosing the right protection method or rose type, gardeners can ensure their beloved plants survive the winter and thrive in spring, keeping their gardens beautiful year-round.
