How cold can the Chinese rose withstand?
The knowledge about the cold resistance of Chinese roses down to how many degrees below zero is brought to you by the editor. Let's proceed with the introduction.
How cold can the Chinese rose withstand?
The Chinese rose can endure temperatures as low as -15 degrees Celsius and has certain cold resistance. When the temperature drops to 5 degrees, water once in winter, wait for the soil surface to be slightly dry, then pile up about 20 centimeters of soil to survive the winter. For smaller Chinese roses, you can prune them and bury the soil outdoors to prevent freezing. When potting Chinese roses, use slightly acidic sandy loam soil rich in humus and change the potting soil every spring.
The Chinese rose can withstand low temperatures of -15 degrees but is not heat-resistant. The most suitable growing temperature is between 22-25 degrees Celsius. Higher temperatures will affect the growth of flower buds and may cause flower deformation. When the temperature is below 5 degrees, the growth slows down and enters a dormant period.
Before the soil freezes at about 5 degrees, water the Chinese rose once in winter. When the soil surface is slightly dry, use dry soil to pile up about 20 centimeters high at the base of the plant. Smaller Chinese roses are not suitable for moving indoors and need to cut off the withered branches after cooling down and bury them in the soil to prevent freezing.
When potting Chinese roses, use humus-rich slightly acidic sandy loam soil spread in the flower pot, apply decomposed special fertilizer, mix well, plant the flowers, water sufficiently, and place them in a position with sufficient light for maintenance. Changing the potting soil every spring helps the plant grow and enhances its ornamental value.
After the flowering period of the Chinese rose, a comprehensive pruning is required. First, cut off the branches after flowering, as well as the intersecting and overlapping weak branches. Retain the outer branches of strong-growing branches, prune from about 1 centimeter above the leaves diagonally, shape the plant appropriately, which not only looks beautiful but can also extend the next flowering period.
That's a detailed explanation of how cold the Chinese rose can withstand. I hope this article can bring you help in green plant management!
