Greene,
Actually, I've seen a similar suggestion via a Facebook post using a pool noodle. I may try that next year. It will frost here in 2-3 weeks and water hyacinths will die. The pond will be covered with netting to keep leaves out. Sqirrels won't be an issue.
In all the years we've had water hyacinths, this is the first year sqirrels have been a problem. Quite a curiosity!
Thanks so much for the suggestions.
