Is Rosa davurica hardy? What is the lowest temperature that can be tolerated? Can it be planted in Chifeng, Inner Mongolia? Is there no heat preservation measure to use in winter?

Rosa davurica is cold-tolerant, and the most suitable temperature for the growth of Rosa davurica is 10 ~ 25℃, the night temperature is 10 ~ 15℃, and the daytime temperature is 15 ~ 25℃. Roses are cold-tolerant, and can withstand the low temperature of 0℃ after dormancy in winter. It is necessary to ensure a certain temperature difference between day and night when the rose buds are bred. It is difficult to grow in Inner Mongolia and Chifeng.

It is good to thicken the soil layer in winter. It can overwinter in the open field in most parts of northern China. Therefore, when maintaining wild rose, we need to give it deep and fertile soil to grow. Just before planting, we need to apply some organic fertilizer.

This will be beneficial to the growth and flowering of wild rose. Because the temperature in winter is relatively low, it is necessary to apply fertilizer once before winter, and the basin soil should be kept slightly wet.

Extended data:

Soil in Rosa davurica;

The winter planting of Rosa davurica has low requirements on soil, and is drought-resistant and barren-resistant, but it is best to plant it in a fertile, humid and well-drained place. Pay attention to the application of decomposed organic fertilizer at the beginning of planting, ditching after one or two years, and applying base fertilizer before winter.

Wild rose watering:

When breeding wild roses, we should water them according to the actual weather conditions from early spring to early summer to keep the soil moist and avoid drought. In summer, especially in drought, we should increase the amount and frequency of watering, and pay attention to drainage in rainy season. As long as it stays wet, there is no shortage of water in autumn and winter. Pay attention to prevent water accumulation in the roots of plants when watering all the year round.

Pruning of Rosa davurica:

Pruning of Rosa davurica should be moderate, especially in winter, pruning diseased branches and weak branches, leaving main branches and removing some side branches to promote new bud germination and healthy plant growth. For potted flowers, attention should be paid to pruning and shaping, and weak branches and buds should be removed at flowering stage.

Fertilization of Rosa davurica;

In the bud stage of Rosa multiflora, pancake fertilizer should be applied to ensure good color and lasting flowering period. Plants grow bigger and bigger, bloom more and more, and need more nutrients, so they need more fertilization, especially at least once in winter and twice a week in flowering.
