Onion maggots - part II

It's funny. Part of the problem is so human. We want to arrange the plants together so that they fit in place, in a row, in a square. It there were more artistry, if the leeks were scattered in a thicket of marigolds and radishes, if they weren't so gathered together so they are ready to 'catch' something, like wildfire, they would have survived. If my garden were a Jackson Pollack, I would be eating leek confit right now.
