Well maybe it is the economy but I have to say Bonnie is now shipping vegetables in four pack cells for $1.79 instead of the standard six pack.  This is 'Bright Lights' Swiss Chard. There is more than 4 plants in the cell pack and I know you can plant several plants in once space. It is a leafy vegetable. Again, with a raised bed you can pack plants together.  Lots of loose soil beneath the plants allows you to do this.

At some point you have to decide if it is worth spending $2.00 for 4 plants. Seeds are cheaper and for instance lettuce is easy to grow. They had a lot of lettuce in four packs but I know I can buy three heads of romaine at Giant for $2.99. So maybe lettuce transplants aren't really worth it. I didn't buy any.

The first step was preparing the bed area for the chard, 'Red Romaine' lettuce and 'Flame' lettuce.

Once cleaned up and turned, I planted the 'Bright Lights' Swiss Chard closer than recommended and on the edge. I know from experience that is grows easily and last all Summer long. I will have easy access to it on the edge. Chard grows fine with 2-3 plants in a clump.
