Using insecticide during high temps
Something is eating the leaves of my young zinnias, is it safe to spray during high temps of 85+? Normally I wouldn't worry too much about a few eaten leaves but these particular zinnias are special to me because of their colors. New to me this year and I hate to see them with ragged foliage. Would dusting with Seven be better than spraying with insecticide (can't remember the brand right now).
