Concrete in soil

I have a nice area along my house for flowers but it was used by builders to wash out the concrete tools. How can I make it usable again?

Doug says the easiest and best, fastest way is to simply dig out the chunks and replace the soil. Failing that, start adding copious amounts of peat moss to this area to start counterbalancing the lime. Sulphur can also be spread and dug into the soil to help. I'd want to take some soil tests (a simple kit from a garden center will do this job) and make sure the pH is back to just under 7.0 before I planted.

So - dig it out and replace or start adding more acidic material to help the natural microorganisms get the soil balanced. And test on this one.
