Please tell me what I should do.. Should I till & put topsoil or just areate and put top soil... There is currently no topsoil ground is hard.That's why I would like to put TopSoil.

Hi,
Do you have an Agricultural Agent in your local area? Or a Farm Extension Service of any kind?
If so, contact them. You can give them soil samples (or clay samples), have them analyzed, and they can tell you what you need to add.
Best of luck.
