Lorax, I love that book! I have all of her Lasagna books, just full of excellent information.
As for raised beds, been doing those for over 20 years, and use wide rows with that. We don't put sides on the beds, I'm too cheap to waste the wood, besides it's more flexible not to add stationary forms. We have a Troybult Horse, so tilling is a snap. We just till in add compost and other amendments, give it another go and shovel the dirt up to about 6-8 inches and start planting. Once we start getting plants in I mulch with grass clippings, leaves or whatever is handy and free
I also use radishes as a marker between my wide rows, helps me keep track of where I left off planting. My beds are normally about 25 foot long and 3 foot wide. With a pathway inbetween, which I normally overseed with annual rye grass. Germinates fast, easy to mow, dies off in the winter and can become the base of a new raised bed for next spring, since it gives a slight nitrogen boost to the soil. I do use white clover as a cover crop under my fruit trees to attract more bees.
Frankly, this method is so much easier to use and your get much better production of both flowers and veggies.
