A longtime zone 6 gardening friend told me her 2012 gardening experiement is using this salad table.
The plans she followed are here. She is a DIY person and said this was easy.
She said it is really working out. One of her challenges was to grow salad in cool temperatures early in the season yet avoid the danger of a killing frost. Her second challenge was that her backyard didn't have a full sun spot all day long, so she liked that this salad table is portable. Lastly, it is a deer infested area and by moving it around she could put it in a safe place overnight.
Salad Tables and Salad Boxes I am saving these plans to consider using, if necessary, after we purchase a permanent home in Texas.
