Some of the leaves on this rose bush are turning yellow. The leaves at the tip are green, so I don't think it is dying. It has recently been put in this spot next to an established rose bush. The other bush does not have any yellow leaves.

There's nothing wrong. The bush is just shedding some of it's leaves. This happens as days get hotter and there's a lack of rain. The bush will shed some leaves to have less to feed. The flip side is when watered well, then it can produce too many leaves which requires more food for the plant to keep all the leaves healthy. The plant will shed some leaves to have less to feed.

This in the picture is something to worry about but yellow is OK.

The appearance of acute injury is seen as interveinal necrosis on the lower four leaflets (left), while the chronic injury is seen as interveinal chlorosis on the three apical leaflets (right; source: Legge et al., 1998).
