OK ... I am clueless on plants, gardening, etc., and have scanned the forums for my problem but don't see anything to match. My son and his friends have evidently been urinating (yes urinating) in my shrubs. They were turning yellow and silly me thought, oh the frost must have done it. Then I thought, wait ... they lived in the snow all winter and it didn't hurt them. Then suddenly it dawned on me ... urine. So I asked and he confessed. So is it fixable (the shrubs not the kid)? If so what do I do? They're boxwoods I believe, or just some sort of holly. We're in KY. Soil is very much clay based. I see all kinds of stuff elsewhere on cat/dog urine, but evidently most people have kids that know not to do this so there aren't any postings on that. Does anyone know of a way to reverse the damage? Someone mentioned lime. Please don't laugh.
