Brussels sprouts grow best in cooler weather between 45°F-80°F. They do great in containers and small gardens. Bank on Seeds recommends transplanting.
If Direct Seeding
- Direct seed outside after last frost date; or
- Direct seed into a container 8-12 inches deep and wide anytime of the year. It can be placed outside when the temperature is between 45°F-80°F; or
Start the brussels sprout seeds indoors 4 weeks before the last frost date in biodegradable pods that will let the roots grow through; clingwrap the top of the container to seal in the warmth. Germination is best and fastest between 70°F-80°F. It can be transplanted outside 6 weeks later.
Sow two to three seeds ¼ inch deep, 20-24 inches apart with rows spaced 28-36 inches apart. Germination will take 8-12 days.
Brussels sprouts like well-draining soil. They also love full sun and regular watering. Water thoroughly and often to keep the soil cool and evenly moist to slow bolting. When watering, do not water the foliage as to deter rot or disease. Check the top 2-3 inches, and of dry, then water it.
Adding a layer of mulch helps in retaining moisture, regulating temperature, and preventing weed growth. Use 5-10-10 fertilizer or aged compost at bloom time for a boost as they are heavy feeders.
Days to maturity take 95-100 days. You can pick the sprouts when they are firm starting at the bottom of the stem. As you harvest from the bottom, the top will continue to develop and get bigger.
