Rose Winter Maintenance
Article Abstract: This article covers the planting of roses, rose winter maintenance, some great tips and knowledge, recommended for collection!
For rose enthusiasts who are planting roses for the first time, understanding rose winter maintenance is also necessary. Although roses are cold-resistant, it is important to keep them warm and fertilized after entering winter, especially for potted roses. The potting soil should be kept moist, especially when cold fronts arrive, be careful not to lose water (avoid waterlogging). For ground-planted roses, you can wrap稻草 around the base to keep warm, and for climbing roses, you can lay them flat on the ground and cover them with soil, and set up windbreaks at the windy spots.
In the north, planting roses should take into account the regional climatic conditions, the cold resistance of different varieties, and the "microclimate" conditions of the planting site, and adopt a series of cold protection measures. Generally, shrub roses can withstand temperatures as low as -15°C, and some small-flowered varieties can withstand temperatures as low as -20°C. In the north, the winter and early spring are often hit by fierce northwest winds. Under dry conditions, strong winds can quickly dry out the upper branches of the plants, causing them to wither from top to bottom, and eventually leading to the death of the entire plant.
The reason for the death of roses in winter is not due to the absolute low temperature, but because of the attack of the cold wind. Therefore, while keeping warm, it is even more important to prevent the wind. Cold protection measures are generally carried out in mid-to-late November, and the methods include:
① For mature plants, you can use covering materials or straw to wrap the base for warmth (before covering, remove the withered branches and leaves to reduce the occurrence of diseases and pests in the following year).
② For larger rose plants, after a light pruning (avoid heavy pruning, which can be done before sprouting in the following spring), set up windbreaks on the northwest side to prevent wind and keep warm.
③ For young plants with small root systems and weak growth, you can bury the whole plant in soil.
④ For potted plants, you can bury the pot in a windless and sunny place, and set up a plastic arch shed outside to keep the potting soil from freezing. If the potting soil is frozen for a long time, it will affect the growth and flowering of roses the following year. For plants placed indoors, the greenhouse temperature should not be higher than 5°C to allow them to have sufficient dormancy.
The above information on rose winter maintenance is provided for green plant enthusiasts as a reference, hoping to solve your problems in green plant and flower management.
