|It's difficult to diagnose the problem because it is unusual for rose leaves to drop without any sign of disease problems. But there are a couple of environmental or cultural problems can stress roses and cause the leaves to drop. Weather can play a part in putting a rose under stress. If the weather turns hot quickly, the rose will often drop its leaves because of the stress. Anything that affects a rose's ability to survive will cause it to drop its leaves so it doesn't have to support them. Water stress can also cause leaf drop. Although you are probably regularly watering your rose the water may not be getting down deep enough and this will make the rose drop it's leaves. You can check by digging along side of the rose to see how deep the water is penetrating. It should go deep enough to wet the entire rootmass. The third reason is that a spray was used, such as an insecticide or fungicide and the rose is reacting to to the spray. I'm sure you know that roses require about 8 hours of sunshine each day in order to perform well and that the spent flowers should be removed as soon as they begin to wilt or drop their petals. Prune the flower and its stem down to a 5-leaflet leaf to encourage healthy new stems and lots of new flowers. Hope this information helps you determine just what's going on with your rose bush!
