I've been reading/seeing a lot of bag gardening lately. People buy topsoil/potting soil/compost from the garden centre in bags, take it home, lay it out on the ground, cut holes in the bags, and plant right in them. Not a bad idea, really, if you're just starting or expanding your garden. The weight of the bags kills the grass underneath. The bags keep your new soil mostly weed free, and help retain moisture.
I, however, am cheap. I don't need to buy soil, I just need to get it relocated from the compost piles in the pasture to where I want my plants to grow.
Last I checked, there was only one pumpkin plant in the back field. The weeds/grass/natural vegetation was taking over the freshly plowed mass of clay. It'll be a lot of work before it starts to resemble a garden.
A bag garden is tempting. But the expense, and then the plastic clean up were turn offs.
Then it occurred to me that paper bags should work just as well.
Walking back, I picked a bunch of clover tops.
