You may be just about to dig out your very first garden. If so we are really excited for you and would encourage you to check out all the information we have for beginners on our Garden page. You probably feel a little behind when talking to experienced gardeners, but did you know there is actually a place you have an advantage over them? Even better, it's the answer to your question of "what do I do with all this grass when I dig it up?"
Try using the grass chunks you dig up to make a natural raised bed or compost pit. As you dig out each chunk, arrange them into a square or rectangle and then just keep piling more on top until you hit the desired height or dig up all the grass. At that point you can fill in the hole with new dirt and you have a beautiful raised bed, or you can toss in your compost and use it like a compost bin. I have used this method a number of times and it works out perfectly, with an added bonus of not having to haul off the grass chunks into the woods an acre away.
