Hello Leila. I have only recently begun using this forum and I am already reconizing some familiar friends. Now then to your roses. Of course the rose season is long over for 2018 and we are soon to be seeing new buds on most plants. In your original post, you say that you planted these two roses a couple of weeks ago, that was then. I suspect they were container grown/supplied rather than bare rooted. You also mention that you feel you may have overdone it with watering. So in your area, the ground was very dry, so watering would not in my opinion affect them, as the water would have soaked away fast.
As a general rule of thumb, plants, trees & shrubs, container grown or bare root need a good soak prior to planting. This enables the body of the plant to quench it's thirst. In practice digging a hole and watering it is good but the water is alread soaking away from wtere the plant is going to sit. Enough about watering except, try and water in the cool of the day.
Most plants will undergo some set back when being planted. The leaves are usually the first indicators that there may be problems. Hence the yellowing etc. Sadly once the leaves pick up the signal that not is all well, the plant will automatically put up the shutters and prepare to close down. Don't waste money on chemical sprays etc.
Now on the brink of a new season. Give the plants a going over. Cut out Once new growth shows any weak, damage growth. Then prune to shape.
