How to Care for Chinese Rose in Winter to Ensure Safe Survival
Do you know these tips? Here are some small experiences on how to care for Chinese roses in winter to help them survive safely. Let's learn together.
How to Care for Chinese Rose in Winter to Ensure Safe Survival
Chinese roses are cold-resistant plants that can withstand temperatures as low as about -20 degrees Celsius, but young and weak seedlings have poorer cold resistance. Some gardening enthusiasts leave their plants outdoors during winter, such as in North China, where temperatures can reach about -15 degrees Celsius, and they can still manage.
If you are growing Chinese roses on the rooftop, generally, they can survive the winter. However, it must be in a south-facing, sunny, and wind-protected area with plenty of sunlight. But we need to note that when the temperature drops below 4°C, Chinese roses will stop growing. Therefore, in the north, cold protection measures should be taken, and the safest method is to move them indoors. So, how can potted Chinese roses be managed and cared for in winter to ensure safe survival?
Ensure Sufficient Light
In late autumn or when winter arrives, the temperature gradually drops, and some of the leaves of Chinese roses may turn yellow and fall off, which is normal. Whether the potted Chinese roses are placed indoors or outdoors, it is essential to ensure they get enough light.
Getting some sunlight in winter can help keep the plants warm and enable the leaves to perform normal photosynthesis. If the winter temperatures are relatively warm and there is plenty of sunlight and nutrients, the potted, flowering varieties of Chinese roses may still occasionally produce flower buds. Since winter temperatures are low, a single flower can bloom for a long time.
Control Watering
If the potted Chinese roses are kept indoors, be sure to open the windows for ventilation regularly. Whether kept outdoors or indoors, the winter watering of potted Chinese roses should be controlled, keeping the soil slightly dry. Because the temperature is low, the roses are generally in a semi-dormant state, so there's no need to water excessively.
Winter Pruning
Chinese roses not only enjoy fertilizer but also require occasional spraying of pesticides to prevent diseases and pests, as well as regular pruning. During the growing season, it's important to pinch the tips, remove extra flower buds, and cut off some faded flowers. Even in winter, some pruning is necessary, and it should be remembered that pruning can be done when the temperature is below 5 degrees.
Before moving them indoors, for one-year-old seedlings with new branches taller than 30 centimeters, cut off 2/3; for those shorter than 30 centimeters, cut off 1/2; and for very young ones, no pruning is needed.
For two-year-old or older seedlings, strong ones should be pruned by 1/2, and weaker ones by 2/3, leaving three to four strong main branches. The branches should also be shortened to concentrate nutrients, which will help them grow more branches and suckers in the spring.
No Fertilizing in Winter
Before spring arrives, you can prune the Chinese roses. Fertilize as needed, using chicken manure, sheep manure, or cake fertilizer, which can be applied to the bottom of the flower pot. Change the potting soil if necessary, allowing the plants to receive more nutrients. This will ensure a flourish of flowers in the spring, with large and beautiful flower buds on the branches.
The above is a detailed explanation of how to care for Chinese roses in winter to ensure safe survival. I hope this article can help you with green plant management!
