About this plant
Brussels sprouts grow small, leafy buds along an upright stalk. They suit all four zone groups (3-4, 5-6, 7-8, 9-10), as a cool-season annual and need full sun with a locally appropriate cool growing season.
Provide fertile, well-draining soil and enough space for their broad leaves. Keep steady moisture throughout the season to support stalk growth and developing sprouts.
Common beginner failures and fixes
- Loose sprouts in an unsuitable season: Follow local planting guidance and select a variety suited to your growing season.
- Crowded plants with weak growth: Space plants according to the variety's instructions and keep weeds under control.
- Caterpillars chewing leaves: Inspect plants regularly, hand-remove caterpillars, and cover young plants with insect mesh.
- Sprouts left until they open: Pick firm, compact sprouts, starting with those lower on the stalk as they become ready.
Beginner checklist
- Choose a variety that fits your local cool season.
- Give plants a full-sun position.
- Prepare fertile, well-draining soil.
- Maintain steady moisture throughout the season.
- Inspect the stalk and pick firm sprouts as they develop.
