I put some low nitrogen water soluble plant food on mine about six weeks before they bloom and then once agaom when bloom time is finished. For the rebloomers I sometimes do this again in the fall. Is this a good thing to do Mary Ann, Tom and Arlyn? I don't use alfalfa as I am afraid to add to much nitrogen to my soil. ??? I have never had a borer in my life. Are borers becoming more prevalent or are they more inclined to be in one region? Now saying that I will probably have a million this year because I have never treated for them.
