Question

Golf ball size growth   QUESTION: 2 months ago I noticed the leaves on my roses were turning brown. I live in Phx. AZ where the summers are hot and temperatures reaches 110 plus. I thought maybe it wasn't getting enough water so increased it.  Since then I have seen balls about just smaller then the size of a golf ball where the blooms were. I've never seen these before and when I asked at Lowe's garden center they didn't know what I was talking about. The best they came up with was some type of insect. The leaves are turning brown and new ones are starting to growing but dry and curl in. 4-5 months ago this bush had very pretty bright shiny leaves and was blooming. There's also 2 other rose bushes within 8-10 ft from this one.

ANSWER: Roses hate high temperatures and will shut down, not bloom anymore and get ready to go into dormancy like it was winter. Roses make a flower and this is where the seeds will come so the rose can reproduce itself. At the base of the flower is the ovary where the seeds are kept. After the flower has fallen off, the ovary looks like a large marble. Finally this marble, or rose hip, falls to the ground and the seeds start to grow and make a new rose. Often birds will eat the seeds and they help to  scatter the seeds around the garden. However when a rose makes a hip, it will not flower again on that cane so I would cut the hips off and when the weather gets a little cooler, the rose will start to make blooms again for you.

New leaves   QUESTION: I am concerned about the leaves turning brown and the new ones folding in and not growing. Tt looks like they're drying up. In the picture you can still some of the original shiney leaves behind. Also the stems have brown spots and I don't know if that was there before. Is this part of the plant going dormant. The rose bush growing closest to this one dosen't seem to have this look. It is a white one and blooms all year long. My yard is rock which I'm sure reflects the heat a lot.

Answer
The leaves in your picture have the same look as when a rose has been hit with a herbicide such as RoundUp. RoundUp drifts a long way even when the spray came from next door. When a rose leaf dies, it don't go thin and curl the way yours are doing. It stays like an healthy rose but turns yellow then brown and finally dopes off. Your rose has had something done to it. The other problem, and I really hope I am wrong, could be that it is suffering from Rose Rosette disease.
Here are some pics of herbicide damage.
