Where should i put this rock at?

This is a random and odd question but oh well. I am taking these two bedrocks out from around two trees we are cutting down. I am going to either put it around my house where there is rock all around already or make a little bedrock behind our shed where there is the trash can and what not. Right now behind the shed, its just dirt and the rock would make it look nice. But itll be harder cause i will have to buy black tarp to put under it so the house is the easiest way to go even though we dont need anymore around the house. lol so what do you think?
