Knockout Roses – Is It Safe To Prune Now?
Q: With such nice weather recently, is it safe to prune Knockout roses?
A: It is safe only if you can confidently predict there will be no more cold weather this winter. Otherwise, pruning now may stimulate buds to swell and these could be damaged in freezing weather later. I recommend pruning in late February when the buds are easy to see and the chance for a deep freeze is remote.
