Q.Killing Lawn With Vinegar
I love the suggestion of using vinegar to kill grass. I would like to put native plants in (I live in the NW) when the grass has died and been cleared away. Will the soil support these plants? If so, what needs to be done to the area prior to planting?

Vinegar poses no ill effects to the soil. Therefore, there is no need to do anything other than prepare the area for planting, which should be amended with organic matter if at all possible. Also, research the plants that thrive in your area and choose these types of plants or at least those with similar growing requirements.
