Close. Slight modification on the instructions from years of personal use and observation:
First of all, if you have any plants there that you want to keep, you must remove them first or very carefully cover. Also, if you spray you have to wait at least two weeks before turning the soil and planting, or you will harm the new plants. 10 days is just cutting it two close.
Personally, I would avoid the chemicals and go with the newspaper, it is very effective and the preferred method DW uses for her garden clients. In this case she would lay down the newspapers, cover with the compost, and then plant directly thru it. Won't harm the plant at all, adds to the compost and betters the soil, and no chemicals to run off into the ground water.
