Protecting Your Roses: Everything You Need to Know About Winter Mounding

Taking care of your roses can sometimes feel overwhelming, with all the pruning, deadheading, pest control, and disease prevention that goes into it. But fear not, our guide on winter mounding for roses is here to make things a little easier for you. Whether you’re a seasoned gardener or just starting out, this practice is important, especially in areas where the winters can be harsh on your precious blooms.

Why Mound Your Roses

Before we get into the nitty-gritty of how and when to mound your roses, let’s talk about why this practice is essential. As the temperatures drop in the fall, roses go through a process that preps them for the cold months ahead. The production of abscisic acid in response to cooler temperatures helps the plant prepare for winter.

Mounding isn’t about keeping your plant warm throughout the winter, but rather protecting the roots from temperature fluctuations between freezing and thawing. This practice is particularly beneficial for hybrid teas, English roses, floribundas, and old roses, as well as grafted varieties.

Not all roses require mounding, with modern types such as Knock Outs, Drifts, and Oso Easy advertised as easy-to-grow options typically not needing winter protection. However, it’s always a good idea to mound your roses in the first year of growth and if the plant has been stressed during the summer months.

When to Mound Your Roses

Timing is crucial when it comes to mounding your roses. Wait until after the first freeze in areas with harsh winters before creating a protective mound around your plants. The ground should be slightly frozen, which typically occurs as the temperatures drop in USDA Hardiness Zones 5 and below.

After you’ve completed your fall pruning, mounding should be the next step. While you shouldn’t perform any major pruning in the fall, cutting back tall bushes to prevent wind damage is recommended. Keep your shrubs around five feet in height, unless you’re dealing with a climber.

Choosing the Right Materials

Selecting the right materials for mounding is equally important. Avoid using materials that can hold water against the soil and stems, as this can lead to root rot or other issues. Grass clippings, whole leaves, and manure should be avoided for this reason.

Instead, opt for loose and well-draining materials such as potting soil, well-rotted compost, straw, finely shredded pine bark, or well-shredded leaves. These materials provide excellent insulation for your roses without trapping moisture that can harm the plant.

How to Properly Mound Your Roses

When you’re ready to mound your roses, start by cleaning up the planting bed thoroughly. Ensuring that no pathogens or pests are trapped under the mound is crucial for the health of your plants. Avoid scooping up soil from the garden to create the mound, as this can damage the roots and remove a layer of protection that the plant needs.

In colder regions (Zone 5 and below), heap about 12 inches of your chosen material around the base of the stem. Less material can be used in milder climates (Zones 6 and 7), with a thin layer of straw added to hold looser mediums like compost in place.

Some gardeners opt to create wire cones to hold the mound in place, while others use evergreen boughs for added support. These cones can be reused year after year, providing ongoing protection for your roses.

Exploring Rose Cones as an Alternative

If you prefer not to mound your roses using traditional materials, rose cones can be a convenient alternative. These cones, typically made of styrofoam, are designed to be placed over pruned plants for the winter. It’s important to ensure that the cones have plenty of holes for air circulation to prevent mold and encourage healthy growth.

Rose cones can be filled with straw for additional insulation, which is particularly useful in extremely cold regions or for young or sick plants. While traditional rose cones can be fragile and challenging to store, newer options like the Rose Cozy offer a more durable and user-friendly solution.

Whether you choose traditional mounding or opt for rose cones, protecting your roses during the winter is essential for their long-term health and vibrancy.

Conclusion

As you prepare for the winter months, don’t forget to prioritize the protection of your beloved roses. Whether you choose to mound them with traditional materials or opt for rose cones, ensuring that your plants are insulated from the cold is crucial. By following the tips outlined in this guide, you can provide your roses with the care they need to thrive year-round.
