Super-hard garden soil?!?

[Bungalocity]

I bought 2 dumptrucks full of Premium Composted garden mix last autumn, and after tilling bits here and there, I noticed after rain or watering,
the stuff gets so hard it almost can't be crumble by hand. It was very fluffy when I was shoveling it into my pit.
Are plants/veggies/flowers/herbs just so tough that they can take through this stuff or should I be mixing something else
into it or putting on top for a more graceful looking appearance??

That doesn't sound right.  I did get one mix that was just terrible.  I had to let it set for 3-5 days from delivery til use, and after a light rain it was just too hard to work.  I bought huge bags of perlite (they call it crum or krum) from Vaughn's in Western Springs.  It lightened up the soil but I've never bought from Tammerling's again.

I think it's good compost soil , I found an old "Hula-Hoe" in my garage that was left there that works
wonders on renewing the appearance of, shallow tilling, loosening fresh-weeds, or simply spreading out
high-points.  It looks like a wooden stick with a metal-handle on the end of it.  It's the simplest tool I have
and the most effective. Any garden center has a version of it!
