Square foot gardening

Well we have been working on getting the square foot garden boxes ready for planting. We just finished putting the boxes together, complete with legs. We are painting the outsides and doing some decorative things. Think stencils. (Photos to follow soon) We are not doing ours on the ground. It will take several more days before they are actually ready for planting.

If you are not familiar with square foot here is the basic premise as found on Wikipedia.
Layout. Don't think in rows, think in squares. Start with a 4 foot by 4 foot box.
Boxes. Create boxes to hold new soil above the ground.
Aisles. Leave at least 3 feet between boxes for walking aisles.
Soil. Use 1/3 good, diverse compost, 1/3 peat moss, 1/3 coarse vermiculite. (Coarse vermiculite may be hard to obtain, especially in UK).
Grid. Make a grid for the top of each box in 1 foot by 1 foot squares.
Care. Never walk on or compress the soil.
Select. Plant a different crop, herb, or flower in each square foot. Depending on the spacing indicated on the seed packet, plant 1, 4, 9 or 16 per grid square.
Plant. Don't waste seeds. Plant only 1-3 seeds per hole.
Water. Don't waste water - water by hand directly to the base of the plant.
Harvest. Add a trowel full of a good, diverse compost after each harvest.
