What do I do with Silver Mound for the winter months? Do I trim down or just leave as they are for the winter? Thank you!

You normally trim back the plant around the middle of summer to get rid of spent blooms and improve its appearance. This plant doesn't require any special care over winter as it will die back and regrow in spring. If it looks ragged, however, you can trim it back some.
