This is the first of 3 raised garden beds based on Ana's plan found here: raised garden beds. My and our twin 5 yr old daughters' job this weekend is to fill them. CAN'T WAIT!
He added a board to the top to make them a little higher. Our first set of boards came from Home Depot, and this box came to around $30. The boards are really rough, so we may sand them a bit as we have little kids and don't want TOO many splinters. Our next 2 boxes will be made from materials from another chain here in Minnesota, Menard's, and they are much smoother (and cheaper - on sale this week for $1.50 a board!)
We also had a really hard time finding outdoor 1" screws, so he used 1 1/4" ones and didn't countersink them.
I am also planning on putting in some landscape fabric inside to help keep weeds out and water/dirt in, since the seams are porous.
