So all, except Coronation Gold, of my yarrow is lying on the ground and the new growth is growing upward putting a nasty bend in the stem. Since I sell cut flowers it is a real pain. My question is, if I can get it tied up and trimmed back to below the bent stems, will it give me another flush of blossoms or will that be it? I don't want to do it unless I may get more flowers this summer yet but next year I will put rings on all of it. I'm talking a 50' row of yarrow.
