Dallas - I have a couple of hostas I just bought that are sitting in morning sun afternoon shade, waiting to be planted. Since I brought them home, a number of leaves have developed "thin" spots - where the upper layer of leaf is left, so it is not a complete hole like a slug would make, but like a layer of leaf tissue is removed. The spots are not on the edge, and aren't large, but distracting. I have had one knowledgeable person comment that this is sunburn, but thought I would throw it out here in case there was another option I could actually treat. Anyone had this happen, due to sun or otherwise?

thanks,

terry
