2011, I spaced my garlic about 4" apart. I was unhappy with the bulb size at harvest July 2012. I'm thinking it was not only planting to close together, but low fertility. If you fudge the spacing, fertility needs to be there.
Fall 2012, This year I went back to 8" spacing in all directions. I planted 5 cloves across and about 20ft long. 150 cloves to the bed.
I added more horse bedding mulch to the bed today.
I planted this bed of beets and carrots early Sept. I'll have to admit I'm not very good at thinning and I sow to thickly too.

So it been over two months and I have only pulled a few carrots.
I just went out and pulled some to show. The carrots are looking pretty good, but the beets are mostly tops. I eat the tops same as chard.

The next two pictures are Spring planted beets. If I spent the time to thin properly they would be much bigger. Still tasty
