Magnolia Scale

Asked July 6, 2017, 6:06 PM EDT

I have a new Magnolia tree that was planted last July. I noticed yesterday that it had white spots all over the branches. The garden company that put it in said that it looked like Magnolia Scale. I saw on your website information about it but wanted more specifics of what to do or if you could recommend an arborist to help me.

Scale unfortunately is not that uncommon on magnolias. Early spring and fall are the prime time to treat them. Here is a link to our publication on scale. A section is devoted to magnolia scale. You may prefer to have a certified arborist treat your tree. You can find one by visiting this site and clicking on Find An Arborist. You can put in your zip code:
