Classes in organic vegetable growing

I have been running a series of classes for gardeners interested in organic vegetable growing. Rather than print out reams of notes I promised to publish my note for the course here. So to see the notes either click on the title above or follow this link:

to find the notes. For those on the course below this page are the pictures of raised beds as used in the Bio Dynamic Care Community in Botton.
