The previous owner of my house had a 1 ft. wide strip of mulch next to the walkway. I'd like to just have grass grow up to the edge of the walkway instead.
However, the ground is extremely sandy. Under the mulch woodchips, there's about 1/2 an inch of dark soil that is probably remnants of the mulch material, and then sand underneath. To my novice eye it basically just looks like pure sand. I'm sure that's not actually true, but it definitely does not bear any resemblance to anything that could be called 'soil'.
The good news is that I can get as much compost as I'd like from the town dump for free. Will mixing the sand and compost at some ratio produce reasonable soil? What ratio would that be? And how deep of a trench should I dig and replace?
Are there any other options that people would recommend?
