I’ve been told by my nursery that my Otto Lyuken Laurels have a huge infestation of White Prunicola Scale. I was also told that I needed a professional to spray them. However I also found out that there is a certain time to spray to be effective. I live in Asheville,NC. Have I missed the deadline to spray? If so, what is the least expensive way to get rid of them; professional spraying or having them dug up and replacing them?

Thanks,

Joan
