Some of my favorite interplantings: Onion sets with any type of greens (lettuce, spinnach, and similar) Radish as row markers. I love French breakfast. Slice them vertically, and spread the slices with peanut butter. YUMMY!! Cabbage among the asparagus. Potatoes between rows of corn planted 1' o.c. (I plant 2 rows of corn, 1 foot apart, then a row of potatoes, 2' from the corn, then an other 2 rows of corn. Potatoes LOVE corn. I mulch the whole thing heavily with hay. Wide row: all of the greens, onions, beets, carrots. Lots of nasturtium, calendula, marigold. Sounds like you're starting out well, Buggseye.
