10. Make a Garden Bed over an Existing Lawn with Cardboard
No funds for a raised garden bed? You can lay down cardboard over the existing lawn to make a garden bed. The cardboard blocks grass and weeds from growing by excluding light and provides an initial carbon layer for the bed. And it would save countless hours of taking sod out and produce healthy soil also! Make sure the cardboard layer has no gaps so that weeds cannot grow up between the cardboard pieces and into your garden.
