Chariot magnolia with white lumps in branches #873356
Asked June 16, 2024, 6:50 PM EDT
I noticed these white hard crusted lumps on my branches of the chariot magnolia tree. These presented this spring, I don't believe these were here in the fall.
1. What are these? (someone said could be white scale?)
2. Is it harmful to my tree?
3. Can this be treated/do I need to treat it?
4. Can/will it spread to other trees/plants if not treated?
5. If untreatable, do I need to have the tree removed, any precautions to take when removing to not spread etc? Time frame for removal?
Thank you for your help and guidance.

HI Tracie,
Looks like magnolia scale. Here is a link to detailed info from the Morton Arboretum. The side tabs have all the information you are seeking. I hope this is helpful.
