Filling your yard with junk is just asking for trouble, especially where your lawn is concerned. Leaving lawn furniture in one place for the entire season can create bare spots in the lawn that you will need to fill in later, so move those patio chairs and tables around.
Be careful about tarps, garden covers and other items as well. Leaving them down too long can kill the grass and give your lawn a patchy and uneven appearance. If you want your lawn to look great all summer long, give it a head start by picking up after yourself – and your kids.
