As far as companion plants, corn and potatoes do fine, although corn is a heavy feeder, while potatoes are medium feeders and do better without as much nitrogen (which encourages foliage rather than tuber formation). However, the other thing to keep in mind is the height of the corn. Plant them on the north side of the garden, so that they don’t shade the shorter potato plants too much. Also, corn, which is wind pollinated, does nicely in the garden when planted in blocks rather than rows.
