The soil (or dirt) is a little dark then sand and remarkably grainy, but too sturdy to even dig near a shovel. we rented an aerator, but that didnt seem to do anything, should we till it adjectives up and lay grass seed and straw? please facilitate! we have the ugliest patio on the block
Answers:    Yes, till the soil. If you till in rather peat moss it will help keep hold of the ground from getting hard.
It sounds approaching you have not easy pan clay. You can till surrounded by compost, peat moss, or perlite/vermiculite to aerate and help it hold hose. Old leaves or straw will take a bit longer to decay and will require adding a bit of nitrogen but will also facilitate condition the soil.
