Generally speaking, most roses can withstand mild cold temperatures and frost, but severe winter conditions can cause some damage or even freeze to death.
Ways to protect roses from the cold
Coverage protection:
Before the harsh winter months set in, you can build a protective layer around your roses. Use hay, leaves, straw, or a specialized winter mulch material around your roses to retain warmth and prevent frost damage. The mulching material should cover the entire rose plant and be secured to prevent it from blowing away.
Reduce watering:
In winter, reduce the amount of watering on your roses to prevent moisture from accumulating in the soil and freezing, causing damage to the plants. Water moderately only when the soil dries out and maintain the proper moisture content of the soil.
Trimming and shaping:
Carry out moderate pruning and shaping before winter to remove diseased, dry or overly long branches. This can help the roses concentrate nutrients, enhance cold resistance, and reduce the parts that are exposed to frost.

Apply fertilizer by burial
The second point on how to grow potted roses in winter is to fertilize them. After the pruning is completed, the potted plants can be taken out of the pot, shake off part of the soil, cut off the rotten and dead roots, and replace them with fresh, fertile and loose roses. The cultivation soil should be well planted, and 50 to 100 grams of retting cake fertilizer should be buried in the middle and lower part of the flower pot to meet its growth and flowering needs in the second year.
Pay attention to cold protection
Generally speaking, the winter in northern areas is relatively cold, so the room temperature of potted rose plants placed indoors should not be higher than 4°C to 5°C so that they can fully dormant.
Tips: Precautions for growing potted roses in winter
1. Pruning must be done before wintering, which can reduce nutrient consumption and reduce indoor space occupied during wintering.
2. Apply fertilizer once before overwintering and water enough. When overwintering, flowers generally need to stop fertilizing.
3. Generally, it is necessary to keep the pot soil dry and water less. The watering time in December is preferably 3 to 4 hours before and after noon. The water temperature should be basically consistent with the air temperature and soil temperature to prevent potted flowers from drying due to excessive water temperature. Low levels cause adverse reactions.
4. Pay attention to ventilation regularly, preferably on a sunny day or at noon when the temperature is high. When ventilating, you must also be careful not to let cold wind blow directly on the plants to avoid adverse reactions.
5. Each kind of flower has its own low temperature tolerance limit. When raising roses in winter, you must prevent the pot soil from frostbiting the plant roots and place the flower pots in a place that does not freeze.
These three principles must be adhered to so that the roses will continue to be beautiful next spring.
Expand your knowledge:

Roses are somewhat tolerant of cold winters, but severe cold conditions can cause damage or even freeze to death. By taking appropriate protective measures, such as covering, reducing watering, pruning and shaping, etc., you can help roses survive the cold winter.
