What would you do differently?
Thank you!

I have a garden in the ground, and I also have two 4x4 foot gardening boxes on the side of my house where I couldn't dig due to gas lines and stuff.
I decided on 4x4 feet because it's not too big to reach around in the box. That size has worked very well for us.
The first year I used non-treated wood and just nailed it together into a frame. That didn't work, as the wood expanded and contracted (or something?) the nails just popped out. The next year my DH fixed them with metal braces on the corners and that has held up wonderfully.
The untreated boards rot very quickly. I have had to make my DH replace them every couple of years. If you want something long term check into other options.
The only downside of my boxes is that they could be deeper. I forgot what size boards we used, the next size up from 2x4...maybe 3x4?
