It is now finally time to address the issue of your lawn ornaments not being secure enough to handle medium to high winds. If your decorations are mostly flat, then you should be able to get away with securing them with garden stakes (either made out of plastic, metal or wood). Yet, things can be a little differently if the inside of the ornament is hollow. In this case, if there is a bottom with a plugged hole, you can fill it up with water to stabilize it. Without a bottom, just simply use gravel or sand instead of water. If there are no holes present, you can go ahead and drill some manually.
