Any guesses what's wrong with this rhodie? There are two in front of the house we just bought and both look like this. Spotted, dull, and dry leaves. Watering doesn't change much. Any thoughts or are they a lost cause?

Whoa - those aren't happy. There's no hope of saving the leaves that are currently on the plants. I'm not seeing any new leaf growth although I can see that they did bloom at one time. Could be any of several issues. Can you give more details about how they're situated? full sun, under the eaves with no rainfall, weed killer spray nearby? Might help pin down the problem.

They're both in full morning sun until probably 2pm, situated close to but not touching the front of the house. There does appear to be a ring of dead grass around one of the plants, almost like someone sprinkled something in a circle around the plant. I'll try to get a picture this evening.

Here's an image of the grass around both plants. There's discoloration in a ring below the leaves on each plant

Shannon are there any other dead grass trails in the yard?

Yes, mainly in high trafficked areas but now that you mention it I see one around our rose bush as well. It had some issues when we first moved in but I deadheaded it and got rid of some dead leaves and it's blooming again

Looking at the Rhodo on the other side of the fence, that looks in good shape, maybe ask that neighbor if they have any insight into what the previous owner may or may not have done...maybe herbicide?

Have to agree with Rj's suggestion. Even though the rose is blooming, it doesn't have many leaves.
