Step 1: Plan!

First, make a scale drawing of your garden - a 4"x4" box in a piece of paper. Grid it off every inch so you have 16 little squares inside of 1 big square. Once you decide what veggies you want to grow, use a search engine to find a website for your state/country and find the recommended time to plant and harvest and the spacing for planting your veggies. Leave some space to plant flowers like Dwarf Sunflowers and French Marigolds that keep away pests.

Step 2: Math time

Now, comes time to do the math. In Virginia, lettuce leaf should be planted 3-6" apart in rows and 12-18" between rows. That means you will only be able to plant two per box. Do the same for all of your veggies. I made two 4'x4' boxes, screwed them together, and grided them 3x6 - a bit harder, but it worked. You just want to make sure you can reach EVERYTHING in your garden.

Step 3: Materials

Now you need to get your supplies.
This is what you'll need.

- 4 1"x8"x4' wood beams
- wood screws
- screw driver
- string
- organic gardening soil w/peat
- carboard
- tape measure
- small nails
- veggies (I bought mine in decomposable pots)
- nice, level, sunny area

Step 4: Make Yo Box!

Screw the boards together so they make a 4'x4' box. Pretty self-explanitory! Then, lay the box where you want the garden to be.

Step 5: Lay the Carboard

With your square-foot garden, you don't want chemicals from any surface ir weeds and grass underneath the garden getting in your garden, so I laid carboard in the box so it totally lines the bottom of the area.

Step 6: Fill it

Put your gardening soil on top of the carboard so the top of the soil comes about 1/2" to the top of the wooden box.

Here is a link that takes you to a site offering a great & free garden planner that coincides with the square gardening approach.

This is a great link. Thanks for passing it along.

Nice quick SFG overview.  I always plant my lettuce tighter (salad mix anyhow), and always have a nice harvest from a couple s.f.  I have a 10' x 10' area and use the Fantastic Farm & Garden Calculator to plan it out.  It makes it really easy to figure out succession planting and intercropping, as well as let you know how many people you can feed.

I am getting ready to do this (South FL) and I want to know if you are happy with the size, I mean would you do anything different if you were to build it again? What about the height - are you sure the plants have enough root room with sides only that tall? Thank you for the tip about tall plants in the back, great job.

Pick a size that suits the area. With the height, you would need to have different heights for what you're growing. If its just herbs, 4". If you are doing tomatoes (tall plants), maybe 6-8".
