I inherited 2 mature wisteria at my new house which is heavily infected by what looks like crown gall.

Should I try and treat the plant by cutting the galls off and sealing the wound with a sealant, or would the best course of action be to remove the plants entirely.

2 other items related to this

1. I want to plant a tree (African Sumac) approximately 5 ft away from the infected wisteria. Is this dangerous given that the bacteria infects the soil or should it be ok since I am planing in a different location?

2. If I do end up removing the wisteria I wanted to plant bougainvillea in its place. Is this a bad idea due to the bacteria in the soil?

Pictures of the galls on the wisteria attached. As you can see the galls are pretty thick at the base of the plant. Thanks in advance for your feedback.
