Chileheads a couple of links to container gardening. This is from a neighboring extension agent - http://www.ag.ndsu.edu/mg/week6/ContainerGardeningcomp.pdf This is a publication we put together this spring for gardeners- it has a section on container gardening. http://www.ag.ndsu.edu/pubs/plantsci/hortcrop/h1405.htm One of the biggest problems with container gardening is that nutrients get washed out when watering. A good liquid fertilizer works great. For organic container gardens, use a manure 'tea' to water and fertilize. Nels in ND
