Adding weight to hollow lawn decorations can keep them from blowing away. Weight can be added in the form of rocks, sand or water, depending on the type of decoration. One of the benefits of using added weight is that it is easy to remove if you want to relocate the lawn ornament.
Wood or plastic stakes can be used to fasten lawn decorations so they don't blow away. Stakes are particularly helpful for large inflatables, and multiple stakes can be used, if needed.
Securing lawn decorations so they don't blow away does more than preserve the look of your lawn. You won't have to repair home or auto damage caused by flying ornaments; you also won't have the expense of replacing the ornaments themselves.
