I get cheap chop sticks, and glue 2 together to make one stake.
Then, drill a hole in the end to run jute string through.
Push down until they won't go any more, then carefully hammer down to below ground level.
The ones that go down easy - just keep moving dirt and pounding till they won't any more.
So far, so good.
