Looks sunburnt to me. We had that heat wave right when everything had pushed out a lot of tender new foliage--the plants couldn't take it. I think your plant will be okay there, but I'd rig up some temporary shade to get it through our next heat wave due Tues-Friday.

It's hard to tell from your photo, but if the growth is gnawed off at a 45 degree angle, almost as if you pruned it, a rodent (squirrel, rabbit, rat, etc.) ate it. If it's ripped off, not at a clean, 45 degree cut, it was something like a cow, horse or deer. It all has to do with how their teeth meet. All rodents gnaw at a 45 degree angle, making their handiwork very easy to diagnose. The loss of all the foliage could be from either deer or rodents, but squirrels, rats and rabbits will strip all the foliage off before gnawing the canes back to the bud union. My suggestion would be to put a chicken wire cage over it so the varmint can't get in to eat it. Make it large and enclosed on top, then bury the bottom edge in the soil and secure it with wooden or metal stakes driven into the ground through the holes in the wire. If it's people messing with your rose, they may, or may not, remove the cage to molest it. You can try Henry's suggestion with silica. You could also try the commercial deer repellants which can be made from chemicals, rotten eggs or peppers. There are also vermin repellants made from predator urine which might help. You are probably going to also smell those products because they are made to smell badly to repel what's eating your plant. Kim

Right, don't fertilize until they have recovered and have put out plenty of leaves. Bloom Buster is the wrong kind of fertilizer--regular Miracle Gro or Miracle Gro for Roses is fine, or any reasonably balanced fertilizer such as 10-10-10 or 18-6-12. Watering correctly is the most important thing. Keep a 2" mulch of leaves or bark around the roses. When the soil under the mulch feels dry-ish, water thoroughly with 2-3 gallons for small plants or 5 gallons for larger, plus or minus for extremely hot or very mild, cloudy weather. Usually once a week is fine. For new plants, I divide the ration in half and water twice a week.

That's what all my roses look like when I start spring pruning, so I almost always cut my Hybrid Teas and floribundas basically back to the ground, or in this case back to where the growth is coming from at the base. Odds are this rose is only hardy to zone 7 (and wouldn't survive in my zone) so most of last year's canes were killed off in your winters. The cane to the far left is definitely alive and looks fine, so prune it back to just above where you see leaves starting. Most of the rest of the canes need to be either cut back severely or taken out. It looks like at least one of the other silvery brown canes to the right is showing some growth, so you could cut those back to growth points. In my experience, roses trimmed back this far can come back just fine from the pruning even if cut to the ground, and you have a fair bit of surviving cane to the left that I'd be celebrating in my zone. Later in the season you could do some shaping pruning of that most preserved cane to even out the shape, but I wouldn't do that till you see how the rose regrows from this point. It's surprising how well the rose can fill in the gaps with growth when it has room to expand. Cynthia
