Hello,


These Robinia pseudoacacia trees are located in italy, I don't know if all of them are joined by a single root system or if there are some different plants

Robinia pseudoacacia is considered an invasive plant in many regions. Our advice is restricted because we do not know your local legal restrictions on pesticides, etc.
