I just made a window box and it’s depth is about 9-1/2” I want to mount it on a shelf as my brackets are not deep enough so I am think of putting the window box on a shelf that will be affixed to my deck fence but I’m wonder should I do a butt joint with glue and screws or do some kind of joint other than that!!!

I butt-jointed together a window box made of cypress ten years ago. I used urethane (Gorilla) glue with stainless steel screws and painted it with white exterior paint. One thing I did that I think helped: I made short brackets from aluminum angle, screwed them into the sides and hung the bottom on them. That left and 1/8” gap all the way around the perimeter of the box for water to escape. I also sized the box to hold rectangular plastic flower pots from the BORG. The soil and plants go in the pots, so there is no direct soil-to-wood contact. The plastic pots make it easy for my wife to change out the plants with the seasons. She just lifts out the pot, does whatever gardening she needs to do in the pot and replaces it when she’s done. The window box is still going strong after ten years.
