Rose stem has 2 even rows (or 1 perfectly braided row) of light colored seed-looking things growing out of it, what are they?
I was doing my spring rose bush pruning and one of my rose bushes (not sure the exact type of rosebush it is) has a green stem has a woody scar about 1-2 inches long with two rows of these light colored seed looking things growing out of it. The two rows are perfectly side by side, sort of look like it could be 1 thicker braided row. The small "seed" thingys have hard outer shells, and when I crush one or slice it open with a razor blade, it has this yellow colored liquid inside.
I cannot find anything online about this, and I'm worried because I don't know if they are insect nests or if they are the product of a very bad infection. I just don't know whether I should be freaking out and cutting the plant down, if I'm supposed to be scrubbing my hands after touching this, etc. Please help!
