White waxy lumps on stems.
I have white waxy lumps on the stems of a hedge in my backyard. When small (2-3mm) they look like a little Mr Wippy icecreams, a conical shape. As they get larger they are more like a blob. When removed they have a pinkish mouth shape on their underside. I pick the large ones off but squash the smaller ones against the stem. Just wondering what they are and weather squashing them is OK or if I'm actually spreading the problem.
