When a cold wind blows, do your roses shiver? Although they bloom radiantly and flamboyantly on weekdays, they are actually quite fragile in winter. Whether you grow noble grafted roses or relatively hardy self-rooted roses, they are likely to be seriously injured by cold wind, frost and the kind of hot and cold weather. So how can you make them survive the winter safely? Here is a complete guide to keeping roses warm in winter – a simple but very practical “heartwarming plan”.
1. Why do roses need winter protection?
Roses may look strong on the surface, but they can’t stand the cold wind and frozen soil, especially in places with large temperature differences between day and night. The roots may be frozen overnight. The key is to keep the temperature of the roots stable, protect the grafting points from being frozen, and prevent them from drying out and branches being broken by the wind. In simple terms, it means to help them wear “thick clothes” to keep them from freezing.
2. Preparation before winter: Key points for autumn management
When autumn comes, many people think about pruning and cleaning, but for roses, autumn care requires “holding back” and “letting it grow naturally”:
Stop pruning the branches and picking the buds. Let it slowly form pods and enter a resting state.
Stop fertilizing – otherwise it will think spring has come and new buds will sprout, but they will all be ruined by the freeze.
The surrounding fallen leaves and debris should be cleared away to prevent pests and diseases from overwintering safely.
Give it another deep watering, and before the ground freezes completely, apply a layer of “freeze-resistant primer” to the roots.
3. Winter protection strategies for different types of roses
1. Shrub and climbing roses (Zones 1-6)
In places where the temperature can easily drop to minus ten degrees Celsius, how can roses not shiver? At this time, you can consider the following methods:
Soil pile protection method : Pile up a 30 cm high “small soil hill” at the roots, and then cover it with some straw or pine branches to keep it warm and breathable.
Flower bulb protection : Use a special “rose cover” to cover the entire top, and remember to leave a small hole for ventilation to avoid it getting suffocated.
Bending method (exclusive for vines) : Gently press the long branches to the ground, cover them with straw or soil, or wrap them up completely.
2. Tree Rose
This type is most afraid of cold, after all, its “neck” (grafting point) is high off the ground, and it will be frozen first when the wind blows:
The roots can also be piled with soil or wrapped with straw to keep them warm.
Build a small frame, cover it with linen or old clothes, and stuff dry leaves or straw inside to prevent wind from getting in.
3. Potted Roses
Don’t underestimate it in a pot, in fact, its frost resistance is much worse than that of ground planting:
Move anything that can be moved indoors , such as into a garage, greenhouse or south-facing wall, to at least block some of the wind.
if you can’t move it – cover the pot with a cardboard box, stuff it with newspapers and dry leaves, and pile some hay outside. It will at least last for a while.
4. Wintering measures in the mild climate zone (Zone 7-13)
If you live in the South or somewhere where winter doesn’t freeze very often, you’re in luck – roses don’t have to suffer that much overwintering:
Simply spread a 2-3 inch thick layer of organic mulch, such as compost, branches, straw or other natural materials, over the roots to not only keep the plants warm but also suppress weeds, killing two birds with one stone.
5. Recommended rose varieties suitable for cold regions
Sometimes, choosing the right variety is more convenient than any protective measures. After all, some roses are naturally “afraid of cold”, and no matter how you take care of them, they are not as worry-free as those “freeze-resistant kings”.
Cold-resistant varieties : such as “Distant Drum”, “Polar Express” and “Modern Centennial Rose”, are all tough guys that can still sprout flower buds in the snow.
Buck Rose : This type is “tailor-made” for the cold Midwest. It is hardy and frost-resistant, so you don’t have to worry about it in winter.
Self-rooted roses : Without grafting, they are naturally more frost-resistant. Even if they are frozen, they can still sprout new buds on their own. They are especially suitable for beginners or people who don’t want to bother much.
6. Spring recovery: timely removal of protection
When spring comes, don’t rush to remove all your protection all at once, as this will make it easier for you to get “cold again” – spring is also a season when things change quickly.
The protective layer can be removed slowly, for example a little at a time every day or two.
If there are frozen dead branches, cut them off decisively so that they can concentrate their strength on new buds.
At this time, it is also time to add some fertilizer and water appropriately to encourage it to “resume work”.
7. Summary: Give roses a warm “winter blanket”
In general, it is not that roses cannot survive the winter, but you need to be a little careful. Roses are actually quite strong, just a little “afraid of the cold”. If you follow these tips, whether you live in the bitterly cold north or the sunny south in winter, you will definitely see them bloom again in spring.
