Hello! I have a beautiful Magnolia-type tree in my from yard. It has large white and pink waxy flowers, and leaves that drop each winter and come back in the spring. However, there are these strange dark reddish bumps on the branches. They look almost like small warts or growths, and you can scratrch them off with your finger. Some branches are fine, others are covered in these strange red things. Does anyone have any idea what this is? I hate to have to lose this tree.
Thank you!

Hellow Hoyden287! Welcome to the forum! Hopefully we can help you!
Sounds to me like you have an insect called scales invading your tree. There are more than 200 species of scales, so you will probably never know which one you have. They are basically a small, waxy, stationary insect. The female is what you are seeing on your tree. The male is a minute flying insect. They have larvae that are soft, tiny and crawl.
At all stages of growth, these insects suck the plant sap, weakening it, and if left with a major infestation, killing the plant.
Prune out any majorly infested plant parts. Destroy these by burning them. Then scrub the scales gently from the branches and twigs with a soft brush and soapy water, then rinse, and spray with neem oil. You should probably spray with Neem Oil every week for about three weeks to ensure that you got any lingering larvae.
If growth has not started on the tree yet for this year, spray your tree with dormant oil spray.
Try and encourage your natural biological controls like ladybugs, birds, etc., although this more of a longterm solution.
I hope you have good luck with your tree, let us know how it goes! Feel free to return with any questions or concerns, or just to chat!

Thank you so much for your help! And thank you too for such a great, warm welcome.
I always thought they looked like insects, but the fact that they weren't moving at all made me think I was wrong. Now I know better. I don't think I would have ever been able to find the answer to my mystery without you!
I'll start working on the tree right away. It has already started to get it's new growth (I live in California, so it's already warming up). I see that it was stated that the Neem and dormant oils are interchangeable. Can I still use the Neem oil while there is such tender growth starting on my tree?
You are so wonderful, thank you for your replies!

You are more than welcome Christina! That's what we're here for! I would use Neem oil if there is already new growth on the tree. Spray it once a week for three or four weeks.
Let us know how it goes, and what happens with your tree! Best of luck!
