Hello, We have an ornamental apple tree (at least 20 years old) that has apple scab. I've treated it for the past 2 years with lime sulphur around the beginning of May. Due to the early warm weather we had this year, the leaves are already close to an inch out and the buds are showing. Any ideas on alternative treatments? Based on info. I've been able to find so far, it's too late to apply the lime sulphur. Thanks, Karen
