I am preparing a new garden bed on a hill side that has many weeds and recently had them all chopped down. Now I want to spray a weed killer on them then I am going to airiate the ground and add some better soil along with some fertilizers. How long do I need to wait after spraying the weed killer before I can start my process of airiating and fertilizing and planting new flowers so the spray does not effect the new plants? |
