Apple tree question

Asked May 14, 2017, 12:25 PM EDT

We have a winter banana apple tree that has developed odd growths on several of the branches. See pictures of one area. The growths look like a mass of pine needles stuck to the branch. They were not there last fall- a lot of growth in just a few months? The tree seems to be otherwise healthy and flowering as usual. Could this be contagious? There is a Braeburn apple tree right next to is, as well as regular forest vegetation (douglas fir, indian plums, ferns, etc). I don't see any growths on any of the other trees, yet. Both apple trees are maybe 7-8 years old and each had a small crop last fall. Neither tree has been sprayed in over a year. Thank you for any information you can share. DeAnna Russelle

You have adventitious roots growing on the branch of your tree, commonly known as burr knot. Unfortunately, there may not be a lot that you can do about this problem as I do not believe Gallex is available to homeowners. The good news is that it is not contagious and will not affect your other trees.
