Entering November, the temperature difference between day and night gradually increases, and at the same time, the cold air is also coming in waves, garden plants begin to enter dormancy, most pests and diseases are also decreasing, and the harm is weakened, but there are still some pests and diseases still occurring, don't be careless. Especially in the warm winter areas south of the Yangtze River on the mainland, the prevention and control of pests and diseases still cannot be sloppy. In addition, the transpiration in November is already relatively low for most areas of the country, which is more suitable for the implementation of tree transplanting, pruning, cold and frost protection, and pruning.
1. Tree transplanting
Entering November, it is a good time for deciduous trees to transplant, at this time, the temperature drops quickly, the transpiration is small, and the low temperature is still high, which is suitable for root development and root wound healing, and is also suitable for wound healing of canopy pruning, which is conducive to improving the survival rate of transplanting. Of course, the colder areas in the northeast and northwest should be carried out as appropriate. For transplanting in this season, we can hand over the rooting water and freezing water after planting, and then cultivate soil for 5-10 cm on the tree tray to reduce the frost damage to the root system in winter. If there are conditions to lay cold-proof materials, it is necessary to focus on the root cold-proof treatment of newly transplanted or transplanted trees within 3 years.
2. Watering:
Entering November, most parts of the mainland have entered the season of little rain, especially in the north and plateau regions, drought has become the mainstream, and reasonable watering is necessary at this time. Watering shallow-rooted plants and areas such as slopes and sandy soils should focus on drought conditions. Watering this month, due to the relatively low temperature, it is recommended to do it at noon.
3. Fertilization:
Fertilization is applied in November, with the aim of storing nutrients and improving the plant's resistance to cold and stress. At this time, fertilization is mainly phosphorus and potassium fertilizer and organic fertilizer, and it is not recommended to apply a large amount of nitrogen fertilizer.
4. Pruning:
The pruning in November is divided into dormant pruning, which is what we often call autumn and winter pruning. This pruning is not only to prune dead branches, diseased branches, but more importantly, to carry out all-round plastic pruning of the tree. The pruned wound should be closed with a wound healing agent.

5. Qingyuan:
Clearing the garden is a critical period for clearing the garden in the green areas such as nurseries, parks, and green streets in autumn and winter. At this time, the garden is cleared, mainly to clean up fallen leaves, plough the land, prune pests and diseases, spray stone sulfur mixture, etc.
6. Cold protection:
Entering November, the cold and frost prevention measures will enter an important implementation period, especially in the cold areas of the north. Cold-proof measures include applying whitening agent, filling frozen water in cold areas (daytime and night-freezing areas), covering soil and cultivating soil to prevent cold, winding straw ropes, thermal insulation cotton and other physical cold-proof. Antifreeze is sprayed in areas with temperatures around 15 degrees in the north and south.
