How cold can tree-shaped roses tolerate?
Tree-shaped roses can tolerate temperatures as low as -7°C. When the temperature drops to 5°C or below, they enter a dormant period, and if the temperature falls below -7°C, the plants may freeze and get injured. Therefore, before winter, it is necessary to water the soil once with a freezing water and apply soil around the roots. The height of the soil pile should be between 30-40 centimeters to provide insulation and keep the plants warm, allowing them to bloom more beautifully the following year.
Tree-shaped roses can tolerate temperatures as low as -7°C. When the temperature drops to 5°C or below, they enter a dormant period, and if the temperature falls below -7°C, the plants may freeze and get injured. Therefore, during winter cultivation, the indoor temperature should be maintained above 10°C to prevent frost damage.
To ensure that tree-shaped roses survive the winter, it is necessary to water the soil with a freezing water and apply soil around the roots before winter. The height of the soil pile should be about 30-40 centimeters to provide insulation and keep the plants warm, allowing them to bloom more beautiful and vibrant flowers the following year.
After entering winter, the growth rate of tree-shaped roses will slow down, and their demand for nutrients and water will also decrease. At this time, watering should only be done when the soil is completely dry, keeping the soil slightly moist, and fertilizing should be stopped to avoid fertilizer damage.
In low temperatures, tree-shaped roses are prone to leaf drop. Therefore, pruning should be done before the leaves fall, removing残 flowers, diseased branches, dead branches, and weak branches. Long branches should also be pruned to reduce nutrient consumption.
