Well that didn’t take long so pour a drink and pull your chair real close to the screen.. The poles are 1/2 inch conduit supporting large tomato cages for our 50 Dahlias. I drink a 2 or 3 bottles of water a week sitting in my Swank Garden office and I was just tossing those bottles willy nilly and when Lady Bender would come out she would rant and rave about them and stick one or two on those stakes until they all had one. Now fast forward several weeks and I notice the moles are digging in the lawn but not near the Dahlias and so I assume the bottle rattle enough in a slight breeze to disturb those rodents....
I do the same to keep from poking my eye out on a stake when I bend over. Recycling can be useful!
Mr Bender, I still think the trees in your backyard are fantastic.
