Prune out all the dead beause dead wood is a good way for insects and disease to enter the plant

I was ready to shovel-prune my Red Wing this Spring, until I noticed that it finally bloomed! Wahoo! Not only that, but the blooms are lace-cap. Very pretty. I started this shrub from a little 4-inch pot baby and after 5 years ... voila! It looks very much like yours. Unfortunately though, I don't have a Viburnum in the area that flowers at the same time, however the berries are still beginning to form/swell. I have a young Cardinal Candy that will hopefully bloom next year and hopefully will bloom at the same time. Anyhow, about pruning. Once I could see where the blooms were, I pruned down some of the surrounding branches so that the flowers (and eventually the berries) will be more visible. Other than that, I'll try to complete any pruning (dead branches and some shaping (not much)) shortly after bloom-time so that I'm not cutting out next year's potential flowers/berries. Best of luck with your Red Wing!

Wow, 30', that's at least three times the normal size, you must be doing something right! I think you mean 30"? Why do you want to prune it at all? This shrub has a beautiful natural horizontal form, and you'll ruin it if you prune the ends of any of the branches. Just remove any dead or damaged branches completely, and remove any water sprouts that stick up inside the shrub.

If you don't have to, no I wouldn't. They're still pretty young, I'd just leave them alone. If there's any die-back or something of that nature, then yes, go ahead and cut that out. But otherwise, no I don't think it's necessary. It's probably trying to put out roots yet, so the stems are still slender. Give it some time, it'll grow. Terry
