Wow! Thanks for the information. I looked it up as well but didn't find all of that info....I must of have had just a bit of time when I did. My son is the only kid in the neighborhood. She is elderly. I'm half tempted to ignore her, although they make sure they are around often. Just this past weekend the guy decided he need to re-mow our yard....my husband already had but he wanted to do it again.
So how do we get rid of the cowitch? Everything we have tried, makes it flourish. Thanks!
