How do Chinese roses survive the winter outdoors in the north
Keep warm: To keep Chinese roses outdoors during the winter in the north, cover the plants with a plastic film to keep warm. Stop fertilizing: As the plants enter a dormant period, their growth slows down and fertilizing is not needed. Reduce watering: Avoid excessive watering when overwintering outdoors, and spray the leaves with a mist instead. Prune branches: Remove diseased and weak branches.
1. -- Keep warm --
Chinese roses have good cold resistance. When the temperature drops below 5 degrees Celsius, the plants enter dormancy. When the temperature drops below minus 7 degrees, frost damage occurs, and some varieties can even tolerate temperatures as low as minus 15 degrees. To keep Chinese roses outdoors during the winter in the north, warming measures must be taken. Use transparent plastic film to cover the plants, tie the bottom with a string, and make a few small holes to maintain ventilation.
2. -- Stop fertilizing --
In the north, the temperature is relatively low during winter. At this time, stop fertilizing the Chinese roses. The plants enter a dormant period with slow growth and almost stop absorbing nutrients from the outside. Fertilizing at this time can easily lead to fertilizer buildup, causing the plants to develop root burns. Chinese roses only need to be fertilized once with organic fertilizer before winter.
3. -- Reduce watering --
If you want Chinese roses to survive outdoors during the winter in the north, do not water excessively. When the temperature is low, excessive moisture in the soil can cause the soil to freeze, affecting the plant's health. It's sufficient to maintain the soil slightly dry, and you can use a mist to spray the leaves to supplement water.
4. -- Prune branches --
In winter, it is also necessary to prune the branches of Chinese roses appropriately. Remove withered flowers, as well as diseased, weak, and yellowed leaves. Overly dense branches should also be thinned for better ventilation. After pruning, disinfect the pruning wounds and then cover the plant with a layer of insulating soil to keep warm.
