Hey, I have a small garden in my front yard, but through years of neglect is pretty much a lost cause. I plan on saving a few things, but pretty much need to re-soil it all. What do you do with the old soil? I imagine it has way too many weed seeds in it to be of any use to anyone. Was gonna spray with vinegar, but then nothing will ever grow in there, can I just use some lime after everything is dead to make the soil useful again, or would replacing the current soil be best?
