When buying flowers in the first pot, if you see that there is new soil in the pot and the stem moves as soon as it is pulled up, then the pot flower must have not grown new roots soon after it is put into the pot. Such flowers are easy to die when bought back.
When two or more of these flowers are planted together, the branches and leaves will gradually become thin and yellow, and the flowers will grow smaller and smaller. The reason lies in the lack of nutrition and the excessive root in the basin, which is easy to harden. Of course, special potted plants are not included.
Some individual traders go up in autumn and winter to dig wild vines and miscellaneous roots to sell as flowers and trees. It is difficult to identify them because they have no stems or leaves.
This kind of potted flower was good-looking at that time. As the plant grows, its shape will change. In addition, binding all the branches and leaves of the plant at the same time not only affects photosynthesis, but also easily produces diseases and insect pests.
The winter cactus is very easy to suffer slight frostbite. There are light green frozen spots smaller than rice grains on the stem or ball. It seems that there is no problem on the surface, but in fact, the internal tissue of the plant has been greatly damaged. If such flowers are bought back without taking measures, the spots will become larger and larger, and finally the whole plant will be necrotic.
