How does a sprinkler head get to your window? The ones I've seen only raise about an inch.
It's raised about three feet about the ground about six inches from a bay window. Normally Canna plants grow there, and it has to be raised or it wouldn't provide enough coverage for the bed.
It's pvc pipe and flexible enough to repeatedly batter the glass in the winds I'm expecting.
After trying the first solution, DUCT TAPE!, I decided that wasn't going to work. I didn't want to cut the sprinkler off, so I braced a very heavy concrete bench seat between it and the window. I'm good to go on that now. It's better than a plywood solution which is good since I have none, lol.
