Many gardeners enjoy the beauty and fragrance of roses in their gardens. However, as winter approaches and the temperatures drop, it becomes necessary to take steps to protect these delicate flowering plants. Overwintering roses in pots or beds is a common practice for gardeners who want to ensure the survival of their roses during the colder months.
There are several reasons why overwintering roses is important. Just like humans, roses can suffer from the effects of extreme cold. Freezing temperatures can cause the plant to die back, resulting in a loss of blooms for the following growing season. Overwintering helps prevent this by providing a protected environment for the rose bush to weather the winter.
One method of overwintering roses involves starting with the rose bush itself. Before the first frost, the rose bush should be pruned and any dead leaves or flowers should be removed. This helps to prevent disease and pest problems that can occur during the winter months. Once pruned, the rose bush can be covered with a cage or wrapped in burlap to provide additional protection from the cold.
If you have roses in pots, overwintering them is a bit simpler. Potted roses can be moved to a protected spot, such as a garage or shed, where they are shielded from the wind and extreme temperatures. The pots can also be wrapped in jute or placed inside larger bags to provide additional insulation. Watering the potted roses thoroughly before the first freeze helps to ensure that the roots stay well-watered throughout the winter.
Regardless of whether your roses are in pots or planted in beds, overwintering them is a crucial part of rose care. By taking the time to protect your roses during the colder months, you are ensuring that they will be healthy and ready to bloom once spring arrives. So, don’t wait too long – start overwintering your roses as soon as they enter dormancy to give them the best chance of survival. With proper protection and care, your roses will thrive year after year.

How to Prepare Roses for Winter
Preparing your roses for winter is essential to ensure their survival during the cold months. By taking proper care and following expert tips, you can help your roses thrive and bloom again in the spring.
Here are some important steps to follow:
- Pruning: Prune your roses in late winter or early spring before new growth begins. Remove any dead or damaged canes, and prune back the remaining canes to about 18 inches. This helps promote new growth and improves airflow, reducing the risk of fungal diseases.
- Watering: Water your roses deeply before the first frost hits. This will help hydrate the roots and prevent them from drying out during the winter. After the first frost, reduce watering to once every few weeks to avoid overwatering, which can cause root rot.
- Mulch: Apply a layer of mulch around the base of your rose bushes to protect the roots from extreme temperatures. Use organic materials like straw, wood chips, or shredded bark to provide insulation and cushioning.
- Protective Coverings: For added protection, consider covering your rose bushes with a protective cage or wrapping them in burlap. This helps shield them from harsh winds and frost damage.
- Overwintering in Pots: If you have roses in pots, move them to a sheltered location, such as a basement or garage, where the temperature remains above freezing. Keep them well-watered but not soaked. Prune the bushes to about 12 inches and remove any open blooms.
- Grafting: Grafted roses are more susceptible to winter damage. If you have grafted roses, consider an additional layer of protection by mounding soil over the graft union or by wrapping it with burlap.
- Frost Protection: When frost is expected, cover your roses with a frost-hardy material, such as a bed sheet or frost cloth, to protect the delicate blooms and foliage from freezing temperatures.
- Care During Winter: Throughout the winter, check on your roses occasionally to ensure they are not experiencing any problems. If the weather is mild, you may need to water them if the soil is dry. However, be cautious not to overwater.
- Spring Care: In early spring, remove any protective coverings and gently remove the mulch from around the base of your roses. Prune them further if needed, removing any dead or crossing canes. Feed them with a balanced rose fertilizer to encourage new growth.
By following these tips and providing the necessary care, you can help your roses survive the winter and emerge strong and beautiful in the spring. For more information on overwintering roses, consult reliable gardening sources and experts in the field.
Coax Them Into Dormancy
For roses to survive the cold winter temperatures, it is important to coax them into dormancy. This means preparing the roses for the winter so they can withstand the freezing temperatures without damage.
One important factor to consider is watering. As the temperatures drop, gradually reduce the amount of water you give to your roses. This will signal to the plant that it is time to start slowing down its growth and prepare for the cold weather ahead.
There are several methods of overwintering roses, but one of the easiest and most effective is covering them. By providing a protective layer over the roses, such as a mound of soil or a cage covered in burlap, you can help insulate the plants from the harsh winter conditions. Wrapping the canes and bud union of grafted roses in burlap can also provide additional protection.
In areas where the winter temperatures get extremely low, it may be necessary to mulch the roses. Adding a layer of mulch around the base of the plant will help insulate the roots and protect them from freezing. This is especially important for hybrid tea roses and other tender varieties.
Pruning is another important step in preparing roses for winter. Remove any dead or damaged wood, as well as any excessive growth that can catch the wind and cause the plant to break. By pruning the roses back to about one-third of their original height, you encourage the plant to go into dormancy and prevent the top-heavy growth that can be damaged by winter winds.
One common reason for rose plants failing to survive winter is because they continue to grow during periods of warm weather in late fall or early spring. These new growths are often tender and can be damaged by frost or freezes. To help prevent this, be sure to stop fertilizing in late summer or early fall. This will signal to the plant that it is time to start preparing for dormancy.
In colder regions, you may also want to consider adding a plate or collar around the base of the rose to protect the graft union. This can be as simple as a plastic plate or a small ring of wire mesh. This added protection helps keep the bud union and roots safe from extreme cold temperatures.
By following these expert tips for overwintering roses, you can ensure that your plants make it through the winter and come back strong in the spring. With a little extra care and preparation, your roses will be well protected from the cold and ready to bloom again when the warmer weather arrives.

Keep the Bushes Well-Watered
Watering is an important aspect of overwintering roses, especially when they are grown in pots or beds. During the colder months, it is crucial to provide adequate moisture to prevent dehydration and frost damage.
If you’re keeping your roses potted, make sure there is proper drainage so they don’t sit in water. Water them deeply to ensure the roots get a good drink, but be careful not to overwater as this can lead to root rot. It’s best to water them when the top inch of soil feels dry.
For roses planted in beds, it’s essential to water them thoroughly before the first hard frost. This will help the plants continue to grow and flower during the winter months. In areas where winters are particularly dry, you may need to water them periodically throughout the season.
One tip for watering roses in winter is to mulch around the base of the plants. This helps retain moisture in the soil and provides insulation to the roots. Apply a layer of mulch that is about 3-4 inches deep, taking care not to cover the base of the rose bush.
Another way to protect your roses from drying out is to surround them with a cage or protective barrier. This can be made from wire or even a plate placed above the rose bush. The cage or barrier acts as a windbreak, preventing cold, drying winds from damaging the plant.
When it comes to watering, keep in mind that roses go into dormancy during the winter months. This means that their water needs are reduced compared to the growing season. However, they still need some moisture to survive. The goal is to keep the soil slightly moist, not wet.
In colder climates, it is best to stop watering roses about two weeks before the first expected frost. This allows the plant to prepare for dormancy and reduces the risk of frost damage. Remember to resume watering in the spring when the weather starts to warm up and the roses come out of dormancy.
If you notice any dead or damaged branches on your rose bushes, be sure to remove them. Pruning can be done in late winter or early spring, before the new growth starts. Prune back any weak or crossing branches to promote better airflow and prevent disease.
In conclusion, proper watering is crucial for overwintering roses. Keep your roses well-watered, but not overly saturated. Mulch and protective barriers can provide added protection against harsh weather conditions. By following these expert tips, your roses will be well-prepared to thrive during the winter months and bloom beautifully in the spring.
