Damaged roses

Asked March 28, 2017, 2:54 PM EDT

The snow two weeks ago damaged my roses and my double knock-out roses which had started to bud during the early Spring weather. I was away and found the damage when I returned 8 days later. Should I cut them way back at this time to allow new growth? When should I fertilize them? In the past I have used the 2 in 1 systemic Rose and Flower care every 8 weeks. I have not had much success with the tea roses. Maybe I should just replace them!!! I am enclosing three pictures taken today (3/28) The double knock-out roses have been great the last three years. I think they will come back! Thanks.

At this point, do not prune just wait and see what grows. Roses are pretty hardy and they should be fine. You may need to do some pruning later.
In general hybrid tea roses can be high maintenance as they are susceptible to insect (rose slugs and Japanese beetles) and disease issues like black spot. It is up to you if you want to care for them.

Look at the attached link regarding knockout roses. They like a soil well amended with organic matter when planting. They do not demand a lot of fertilizer. Make sure mulch is no thicker than several inches and keep away from the stems. Water during dry periods. Periodic fertilizing, following soil test recommendations, will give the best flowering and growth. http://extension.umd.edu/hgic/rose-rosenot-always-look-%E2%80%98knock-out%E2%80%99-landscape-roses
