Weeping pussy willow
I have two weeping pussy willow trees in my yard. We just bought this property last year and so this is my first spring here. I noticed these bulbs (not the blossoms) on the branches and wondered what they are and what I should do, if anything. Thank you!

The growth on the stem is a gall caused by a midge (small flying insect), in this case, probably a willow beaked-gall midge (Rabdophaga rigidae). These galls usually do not affect the health of the plant so no control is needed.
