How to Protect Roses for Winter
Roses can be surprisingly tough, but winter conditions in many colder climates can still challenge even the hardiest varieties. Cold snaps, drying winds, freeze–thaw cycles, and inconsistent snow cover can all take a toll. A little extra protection in fall can make a big difference in how well your roses return the following spring.
This is especially important for David Austin roses, English roses, hybrid teas, and other less-hardy or grafted varieties. While many roses can survive colder climates, protecting the crown, roots, and graft union greatly improves their chances of making it through winter in good condition.
Here’s how to prepare your roses for winter in colder growing regions.
1. Stop Fertilizing by Mid to Late Summer
By late summer, your goal shifts from encouraging new growth to helping your roses prepare for dormancy.
Stop fertilizing around mid to late summer so the plant isn’t pushed to produce tender new growth right before freezing temperatures arrive.
You want existing canes to begin hardening off naturally as days shorten and temperatures cool.
2. Keep Watering Into Fall
Don’t stop watering just because the growing season is winding down.
Continue watering your roses as needed through fall, especially during dry periods, until the ground begins to freeze or winter rains take over.
Going into winter with adequate soil moisture helps protect roots from stress. Aim for deep, infrequent watering rather than light, frequent sprinkling.
3. Avoid Heavy Fall Pruning
It can be tempting to clean everything up before winter, but major pruning should be saved for spring.
In fall, focus only on:
- Removing diseased leaves and plant debris
- Cutting out dead or clearly damaged growth
- Cleaning up fallen leaves that may harbor disease
If your rose has long canes that may whip in strong winter winds, you can shorten them slightly to make the plant more manageable. Otherwise, leave most of the structure intact until spring, when you can clearly see what has survived.
4. Mound the Base of the Rose
One of the most important winter protection steps for roses in colder climates is mounding.
Wait until the rose has gone fully dormant and you’ve had several hard frosts. You don’t want to insulate the plant while the soil is still warm.
Once conditions are right, mound approximately 8–12 inches (20–30 cm) of clean soil, compost, or a soil–compost mix around the base of the plant.
The goal is to protect the crown and lower canes.
If Your Rose Is Grafted
Pay special attention to the graft union, the swollen area where the rose variety is joined to the rootstock.
Make sure it is completely covered by the mound.
In colder regions, grafted roses benefit if the graft union was planted slightly below soil level. Even if upper canes suffer winter dieback, the protected base has a better chance of surviving and regrowing.
5. Add a Thick Layer of Insulation
After mounding, add 6–12 inches of loose insulating material over and around the base.
Good options include:
- Dry shredded leaves
- Dry leaves
- Straw
Leaves are especially effective because the air pockets between them help trap heat and insulate the plant.
The key is to keep the material loose and airy, not compacted or sealed.
6. Build a Protective Cage for Tender Roses
For David Austin roses, English roses, or other less-hardy varieties, consider adding an extra layer of protection.
Create a cylinder around the plant using:
- Chicken wire
- Wire garden fencing
- A rose collar
Then loosely fill the structure with dry leaves.
This creates a deeper insulating zone around the lower canes while still allowing airflow.
For valuable roses in colder climates, this method is often more effective than wrapping with burlap alone.
7. Use Snow as Natural Insulation
Snow is one of the best natural insulators available.
Once consistent snow cover arrives, you can gently shovel or pile additional snow around your protected roses.
A deep snow layer helps stabilize temperatures and protects the crown and lower canes from extreme cold.
Don’t Wrap Roses Tightly in Plastic
Avoid wrapping roses tightly in plastic for winter protection.
Plastic can trap moisture, encourage condensation, and increase the risk of rot and temperature stress.
Instead, focus on breathable insulation methods like soil, leaves, straw, and snow.
8. Uncover Roses Gradually in Spring
When spring arrives, resist the urge to uncover everything at once.
Weather can shift quickly, and warm spells are often followed by late frosts.
Instead, remove winter protection gradually as temperatures stabilize and the ground begins to thaw.
Start by removing some insulation to allow airflow, then slowly uncover the base as conditions improve. Finish by gently pulling back the soil mound once the risk of hard freezes has passed.
Avoid leaving wet, heavy organic material packed around the crown for too long in spring.
What I Would Do for David Austin Roses in Cold Climates
For less-hardy roses like David Austin varieties, I would not rely on mulch alone.
Instead, I would combine:
Soil or compost mound + wire cage filled with dry leaves + natural snow cover
This layered approach protects the crown, graft union, and lower canes from multiple winter stresses.
Some cane dieback is still possible after harsh winters, but protecting the base ensures the plant can regrow strongly in spring.
For Extra-Special Roses: The Minnesota Tip Method
For especially valuable or tender roses, there is a more advanced option known as the Minnesota Tip.
This method involves carefully loosening the plant, bending it toward the ground, securing it, and covering it with soil for winter.
It provides excellent protection because the entire plant is insulated by the earth.
However, it is more labor-intensive and is usually reserved for roses that are particularly prized or not reliably hardy in your region.
A Little Fall Work Goes a Long Way
Growing beautiful roses in colder climates often requires a bit of extra effort, but it’s well worth it.
The most important step is protecting the base of the plant.
Allow roses to enter dormancy naturally, mound the crown and graft union, add insulating layers, and use snow when available to your advantage.
In spring, uncover gradually, assess winter damage, and prune back to healthy growth.
With the right preparation, your roses can return each year strong, healthy, and ready to bloom beautifully again.
