What is a cheap way to get weeds out of gardens?

Spray vinegar directly on the weeds or you can use boiling water. You can read my Hometalk post about it here: http://www.hometalk.com/diy/outdoor/pest-repeller/save-your-garden-sprays-28593963

Hand pull them!! It's also the most effective.

Hand dig anything that grows from other roots, there is no way to get rid of them because they just keep coming from plants beyond the garden. Once you are rid of all the weeds you can get put down a weed preventative to control the regular leaves. This will not stop any seeds from trees as they are not a weed.

thanks i guess it's a never ending thing

It is never ending! Put heavy black plastic down in between your rows. It will suffocate the weeds. Vinegar works well as a spray, too. Or layers of newspaper helps to keep the weeds from growing also. Then in spring, the newspaper can be tilled right in.

i think i remember something about putting newspaper down.. i think it's in the ink. thank you for jogging my memory.
