Plantagenet is a deciduous tree, so it will lose its leaves in winter. So when does the broom lose its leaves in winter? It depends on the local environment. The defoliation of broom is related to temperature. I am in Guiyang, where the broom leaves its leaves until the ginkgo leaves are bare, so it gradually leaves its leaves after 65438+mid-February, and the defoliation temperature is between 5- 10 degrees. In Guangdong and Guangxi, defoliation is estimated to be a little late, so it can't be said when defoliation will take place, which is mainly related to the regional temperature.

After the broom leaves fall, there are many things to do, which shows that the wintering activity has begun. At this time, what we need to do is to trim and supplement the overwintering fertilizer, clear the garden in winter to prevent and control pests and diseases, reduce the overwintering base, and trim the branches we don't need, ensure a certain ratio of crown to width, and keep the shape. Then bury the overwintering fertilizer in the flowerpot, and finally spray fungicides and pesticides once to kill the overwintering eggs and germs.

Second, how to raise potted pyracantha

Pyracantha is called "saving the mother" here. It used to be eaten as a meal. It can be said that people in their sixties have special feelings for pyracantha. Pyracantha fortuneana has strong adaptability to the environment and is particularly cold-resistant. It can overwinter in Guizhou, with no special requirements for soil environment and no pests and diseases. Its resistance is extremely strong. I don't think there is anything special to emphasize about the protection of pyracantha. If it is a bonsai, I think it is mainly nutrition and pruning.

1, basking in the sun

Pyracantha is not afraid of the sun. The more sun you get, the better you will grow. You should bask in the sun all year round. It is suggested that the curing environment of pyracantha fortuneana should have sufficient light. The environment is too cloudy to grow well.

Step 2: Trim

For pyracantha bonsai, it should be trimmed frequently and bent reasonably to ensure the shape. Cut hard in the early stage, and the harder you trim, the better. We just need to leave branches in the shape we need. After a period of germination, new branches will soon burst into pots. There are many shapes of pyracantha bonsai. I mainly like cliff shape and pagoda shape, which are more imposing. Of course, I suggest playing with modeling according to the trend of the pile head.

Through our introduction, I believe that we have a deeper understanding of what should be paid attention to when changing pots of pyracantha in autumn, and which is better for brome and pyracantha.
