Bartholomew's plans call for 4'x4' boxes with space for walkways around the edges. This makes the perfect size to reach the garden from all sides. Not having the luxury for space, we cut this down to 2'x4' boxes since we wouldn't be able to access the back of the box. So adjust your materials accordingly if you go full size.
MATERIALS we needed for 2 2'x4' boxes:
- 3 pieces of 1"x6"x10' lumber*
- screws (we used 2" decking since we had some laying around)
- covering for the bottom (we used old window screen, but plastic, fabric, plywood would work too)
- industrial screws
- compost, newspaper, potting soil of choice (See Bartholomew's site @ http://www.squarefootgardening.com
for his super mixture. This should probably vary depending on what you will be growing though.)
- Plants and/or seeds
- Saw (we used a jigsaw since we are masochistic...I mean live in a townhouse and don't have the room for a table saw)
- Industrial Stapler
- Electric Screw Driver
- bonus for reclaimed lumber, but sadly since the building slump hit our area pretty hard and we haven't had any hurricanes (knock on wood) recently, recycled/reclaimed lumber is hard to come by. Use poplar if you can afford it, some plants dislike pine and pressure treated could release chemicals into the soil (or so I heard).
