I mentioned "double dug" in the first post & this is a technique I see touted around. As the name implies, the garden is dug twice the normal depth. (18" to 24" or so) The next principle of the technique is to plant with closer spacing than normal; they say on a hexagonal pattern.
So I have this little plot I used this on, layed out in a Goleden Rectangle (a little magic never hurts, right?). I haveplanted veggies in it 2 years now & veggies is what grew. I can't say if this technique is more productive than the normal techniques as this is my first veggie garden.
I can't find pea seeds in the regular stores yet so nothing more to tell for now. Happy gardening.
