Big sigh of relief. Thank you so much Dr. This is the first year I have paid this much attention to my semps. I may have had them before and never noticed it. However when I have harvested plants for trading I have always checked them closely and have not seen signs of pest before. I have isolated these two new plants that have the aphids and will treat them in hopes of not spreading the little pest.
I will use Jacki's recipe above on both of them. Will report my results.
Thank you so much Dr. Houseleeks. I will sleep well tonight knowing all is well.
