Q.Should I stake my wax myrtles?
I have several wax myrtles and two in particular I am growing for privacy and screening. However, they have a habit of flopping over with heavy rain. Last winter they flopped over all the way to the ground when we had a hard frost. I was able to reposition them after the ice melted and after heavy rain they do spring up but this habit is not providing us with a reliable privacy screen that we need.
Late last winter I pruned them both back hard in the hopes that they would be more robust but it doesn’t appear to have helped. They were both hanging over like weeping willows following a hard rain. So do you think I should stake them, and if so, how?
Thanks!

Yes - I would recommend staking your trees to prevent them from flopping over. Here is an article that will guide you on how to stake them:
