Here is what I talked about on the radio show. Using a bag of miracle grow dirt for a salad growing table.

It's a simple, weed-free way to grow lettuce, spinach and even radishes. Take a 2 cubic feet bag of potting soil ( used Miracle Grow), rumple it around quite a bit to loose the soil, poke quite a few holes in the back side for drainage, then lay the bag on a smooth surface that will allow drainage and not get too hot, and cut out the top, leaving about a 4 or 5 inch border all around. Lightly rake through the soil to even it out and loosen it even more, then carefully, and evenly sprinkle the seeds around.  Put the salad green seeds in an old spice bottle with large shaker holes, added some cornmeal, shook it all up to mix well and sprinkled them out of it. You can put the cornmeal in there to allow  to see that you had covered the soil evenly. If doing radish seeds or spinach, just make lines the depth mentioned on the seed pack, plant the seeds and cover appropriately. For salad greens you can sprinkled a lite covering of soil over the cornmeal and seeds and then spray-misted to water them in. It is suggested to  put your bags on metal sawhorses and grates to make them waist level. This kept the bags off the hot concrete or cold wet ground and then you  didn't have to bend over when cutting your salad. When harvesting, just use a pair of scissors and cut what you need - don't pull the plants out. Same goes for spinach.   I will be planting this in the greenhouse this week.  So I will post pictures on how I did it.  Then post pictures of it growing.  HOPE you enjoy.  Spring is coming I promise.
