Climbing Rose Leaves Are Turning Yellow Then Brown With Brown Spots

Question From: NEW MEXICO
Q: Hello, My large climbing rose leaves are starting to turn yellow on the edges and then develop into the entire leaf that becomes somewhat brown with tiny brown spots. This seems to go up the entire bush which faces west and is about 15' tall. Any idea what and why this is occurring ? Thank you so much,

A: Your roses probably have a fungal disease called black spot. Take photos of the plant and samples of the leaves to an independent garden center for an accurate ID and method of control. Early treatment next year will keep the foliage clean. Best Nancy and Happy Yrdening
