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.
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. Best And Happy Yardening, Nancy.
