Description

(Brassica oleracea). Groninger is an easy-to-grow, steady-producing variety. These medium to small sprouts are an ideal choice for first-time gardeners. Sprouts form a tight head and maintain a delicate flavor even in variable weather. Groninger Brussels sprouts can handle a light frost and will improve in flavor with the cold weather. This variety has received the RHS Award of Garden Merit.

Growing Tips: Groninger Brussels sprouts thrive in cooler weather and require consistent moisture for the best growth. They are known for their cold hardiness and produce compact, flavorful sprouts on sturdy stalks. Regular feeding and mulching will help the plants maintain healthy growth throughout the growing season.

When to Grow

Start seeds indoors 6-8 weeks before the last frost date in your area. Transplant outdoors when seedlings are 4-6 weeks old and after the danger of frost has passed. In milder climates, direct sowing in early spring is also possible. This variety is particularly suited for fall harvesting, as the cooler temperatures enhance the flavor of the sprouts.

How to Sow and Plant

Sow seeds 1/4 to 1/2 inch deep in seed-starting trays or pots filled with quality seed-starting mix. Maintain soil temperature between 50-75 F until germination, which typically takes 7-10 days. Once seedlings have developed two sets of true leaves, they can be transplanted into the garden, spaced about 24 inches apart in rows 24-36 inches apart.

How to Grow

Groninger Brussels sprouts require full sun and rich, well-drained soil with a pH of 6.5-7.5. Regular watering is crucial, especially during dry spells. Fertilize with a balanced fertilizer once every few weeks to encourage robust growth. As the plants mature, remove the lower leaves to help focus the plant’s energy on sprout production. Harvest the sprouts when they reach 1-2 inches in diameter, starting from the bottom of the stalk and working your way up.

How to Save Seeds

To save seeds, allow some plants to overwinter in the garden. Brussels sprouts are biennials, meaning they flower and produce seeds in their second year. In spring, they will produce yellow flowers followed by seed pods. Once the pods have matured and dried on the plant, harvest them and thresh the seeds. Store seeds in a cool, dry place.
