It's a wonderful article, filled with useful and very practical information. When are you going to write a book?
I need to practice more companion gardening, although I do already plant radishes and carrots together in wide rows. The radishes come up quickly and remind me to keep watering the carrot seeds. The carrots are shaded a bit by the radishes, and when I've harvested all of the radishes, the carrots have plenty of space to grow into the loosened soil. Also, the worms that like carrots like radishes better, so they are a trap crop. Growing long rooted radishes has a definite advantage, as the worms enter the root early and are usually only in the bottom 1/3 to 1/2 of the root, leaving most of it for us.
Wide rows? Why? More space for plants and not so much wasted on pathways between them.
