As I have not used my raised vegetable garden for say 3 seasons, it is now pretty well grown over in grass.
((we are talking about a 8 ft by say 6 ft area here.)) last fall I added what leaves I could get, to it to help smother out said grass and it did do some good. however as we have no trees to speak of yet, I was only able to cover a portion of the area.
Now it is time to plant my
potatoes, and I would like some advice as to how to proceed.
I have found several
weed killer recipes online--
gin/cider vinegar/dish soap/water
vinegar/salt/dish soap--etc,
but as I really want to plant this year is there a simple, effective, yet safe way to rid myself of this grass?? none of these online recipes have any advice as to when the area would be safe to use again.

Please keep in mind me using a shovel and digging out all the grass is a last resort---I dont think my back would be too happy if I used a shovel for that length of time.

Thanks in advance
