Anne Phillips of Go Green Gardeners has come up with a great idea to grow vegetables vertically. She created a vertical salad garden, which is about 2.5 feet wide and nearly 5 feet tall. She used a French riddling rack, boards with slanted holes in which fermenting bottles of sparkling wine were perched nearly upside down, so yeast could collect in the neck and be removed. She wrapped the backside of each plant with coconut coir fiber, the kind typically used to line hanging baskets, and then packed dirt around the roots. The salad garden she created looks quite good to put it on a deck or patio. Even though not all plants work in this kind of setup it’s practical anyway. Besides, you can use the idea and make such vertical garden from wood boards.
