LOML has numerous flower beds scattered about and likes it when I save my sawdust from the DC for use in the bedding. I was just about to start doing a bunch of jointing/planing on some Walnut and she said I shouldn't put that in any of her gardens. Now, if memory serves me correctly, I believe Walnut is a no-no for animal stalls, but does the same apply to flower beds? BTW, these ARE just flower and plant beds, not edible type vegetation. Can someone clue me(us) in?
