How do ground-planted roses survive the winter in the north?

There are many varieties of ground-grown roses in the north, and some varieties can withstand temperatures as low as minus 15 degrees Celsius or even lower. However, as the temperature rises in winter, growers need to take reasonable cold-proof measures and wintering management to greatly improve the winter survival rate of roses. So how do roses planted in the north survive the winter? Let’s take a look with the editor below.

1. Pruning branches

When the temperature begins to drop in winter, prune the roses, remove yellow branches and leaves, weak branches and crossed branches to keep the plants well ventilated and exposed to light. When pruning, leave a healthy main trunk and outward-growing buds so that the plant will grow better next year.

2. Temperature control

The suitable temperature for rose growth is 15℃-25℃. In northern regions, make sure the plants are within this temperature range. Heating equipment such as geothermal wires can be used to increase the soil temperature, but care should also be taken to prevent burns caused by excessive temperatures.

3. Branch protection

For roses with relatively high branches, they need to be pruned as a whole after winter begins, and then covered after pruning. After pruning the branches, you can gather them with a rope, and then wrap them with sponge or cloth to keep them warm.

4. Pest and disease control

Winter is a good time for pest control. Lime sulfur and other agents can be used for spraying to kill pathogens and pests. Pay attention to check whether the plants have signs of diseases and insect pests, and take timely preventive measures if found.

5. Water and fertilizer management

Roses grow slowly in winter, so the number of watering should be reduced, and the principle of not watering unless the soil is dry and watering thoroughly when watering should be adhered to. The plant will temporarily dormant in winter and it does not need nutrients during this period, so stop fertilizing during the winter.

6. Soil Cover

Gently cover the roots of the roses with a good covering material such as sand or straw to keep them warm and prevent cold air from directly contacting the roots. Add soil to the roots of the roses and cover them with straw, sawdust, etc. to keep them warm.

7. Wind protection

Roses in the cold northern regions are afraid of cold winds, so it is very necessary to protect them from wind, for example, by covering them with thick kraft paper. You can also dig the soil on one side of the rose deeper, lay the rose down, bury it in the soil, and then dig it out in the spring.

The above is an introduction to how roses planted in the north can survive the winter. Roses themselves have a certain degree of cold resistance. Generally speaking, through reasonable care and management, roses planted in the north can survive the winter safely.
