Is it illegal for the property to unplug the plants planted by the community owners?

It depends on what you are and where you are.

If you plant non-green plants such as vegetables, whether you plant them in your own garden or in the * * * area of the community, the property can be handled, because you have violated the relevant regulations on community greening. However, if it is planted in your own garden, the property cannot be pulled out by yourself, because it is planted in your own place and belongs to private goods, so the property cannot be enforced, but the property can be pulled out by relevant departments, for example.

If your plants are in the use area of * * *, no matter what you plant, the property has the right to pull them out.
