Brussels sprouts are among the most interesting vegetables you can grow. With rows of tiny 1- to 2-inch cabbage-like heads growing along a 2- to 4-foot stalk, Brussels sprouts are a must-have brassica for your garden.
Brussels sprouts like cool weather and can handle a mild frost, but cover them if you anticipate a hard freeze. Plant in full-sun, sandy loam with good drainage. Don’t be in a rush to harvest your sprouts in fall—a light autumn frost actually improves their flavor. Start your seeds indoors 1/4- to 1/2-inch deep, then transplant seedlings outdoors. Place your plants 18 to 24 inches apart, in rows 30 to 36 inches apart.
Brussels sprouts require patience: They are ready to harvest approximately 20 weeks after sowing. They need to be started indoors for several weeks to jumpstart their growth before transplanting outdoors for an additional 60 to 100 days of outdoor cultivation.
