Q.Winter care of a dusty miller
I didn’t realize how big the dusty miller would grow. I have 4 of them planted together and want to move 3 of them. Do I need to trim them down for winter and then replant in spring? I live in Oregon, in the suburbs of Portland..
Dusty Miller should be hardy in zones 8 - 10.
It could be a tender perennial in your zone 8 area.
I would add some winter mulch protection and wait until spring to lift and divide the plants.
