When I had a large plastic g/h I lashed it to the concrete fence post with rope. It meant I had to crawl in, but the exercise was good for me and it didn't blow away. I did dismantle it every winter, dried it out and stored it well and it lasted until I could afford a proper glass one. I then gave it to some friends, who didn't tie it up to anything and it blew away.
