Good Morning Mary,
Thank you for contacting the U of M Extension Service.
Please click on the following link from the U of M Extension Yard and Garden website:

Control is generally not suggested. Please read through the information. As you scroll down, you can expand the sections that discuss protecting your plants.
The above information states:
- Can be a problem when galls are numerous on very young plants.
- Damage may occur if there are many galls on branches or present for several years in a row.
- In most cases, galls are not numerous enough to harm the plant.
Good Luck!
