After studying companion planting for a while I decided on this guild in one of my raised beds. The only problem I can see is that the corn will get fairly high and I will need to cover them somehow to keep the critters off. It all seems to be growing well together, two rows of corn on a diagonal, potatoes here and there, and six zucchini plants intermingled with a trailing rosemary bush and 1 eggplant. As the potatoes grow I am just heaping up some soil and sugar cane mulch around them, leaving the zucchinis to get a little shade from that and the corn. So the level of the bed is uneven and I wasn't worried but then realised I haven't seen anyone else do it. Anyone tried this combo or an uneven bed?
