Some vegetables, like lettuce and asparagus, are grown for the thrill of an early harvest of fresh tasting produce for the table. Brussels sprouts are a late thrill. The ultimate cool weather crop, their flavor is actually improved by a touch of frost. Hence, plantings are timed to mature just when days are still warm and sunny but night frosts are just beginning. The plant is slow growing but makes up for it by being frost hardy. Picking continues well into fall and even winter. The mature plant looks like a palm tree with big floppy leaves on top and little round sprouts growing tightly all up and down the trunk. Each plant yields about a quart of sprouts; they freeze well.
Well, to grow Brussels sprouts in a sunny, well drained plot. Thus, it takes a long time to mature reserve it a spot for the whole season. You can interplant small and or early crops between the rows. If there is a way to shield it from the wind without shielding it from the sun, do so. The tall mature plants can blow over.
