My mother came to visit a week and 1/2 ago...oh sorry, mom...what a bum thing that when we ran into town we just plain forgot to buy weed spray. I don't believe in chemicals as previously stated. Little things like that, I don't have time to worry about. And there wer ornge/red marigold seedlings in bloom popping up right in my new old sidewalk and all along the crack rof the cemente right under my front door. Well, my mother became obcessed or bored and pulled them ll while my dad and I were doing electrical wiring. I thought, wha do they hurt? I remember reading in magazines and books, non-chemical things to use...things right out of your own kitchen. Problem is, I can't remember what have read when I need to. My mind is just blank, and all my books are still packed up. I seem to remember vinegar, hot water...hey, these are too industrious for the bleach water from wall washing before painting that I through on them...I truly appreciate how very everyone on this site is. Thank you.
