What Causes Rose Bush Leaves To Turn Brown Starting From Outside Of Leaves

Question From: Laguna Niguel, California, United States
Q: What causes my rose bush leaves to turn brown all around the edges? the brown slowly envelopes the leaf and it falls off.

A: Your roses are probably going dormant. I live in Michigan and am not familiar with the techniques of growing roses in California. I suggest you check out the rose growing books at your local library. Also check out the America Rose Society website for information where you can find classes in your area.
