can I prune lavender, dusty miller plants?
we had an unusual minus 9 degree night this winter (zone 7/5200 ft.) & the lavender & rosemary look like they died back. Can I prune back the lavender & rosemary (upright & prostrate varieties)?
Some 50 yr. old roses survived just fine but some younger (+7 yr.)ones have a lot of dead wood. Would like to cut them back to maybe a foot off the ground (above the graft)?
Also the dusty miller plant is as big as a bushel basket with long branches... can/should it be pruned back? It survived the minus 9 just fine but it is SO big & wonder if it would do even better (bushier, more flowers)if pruned a bit. We lost a lot of things to the freeze but hope some may come up again from the roots.
