Description

(Brassica oleracea). Groninger is a steady, easygoing Brussels sprout that performs beautifully in a wide range of conditions. Medium to small sprouts form tight heads and keep a delicate, refined flavor even when weather shifts around. It handles light frost with ease, and the flavor only gets better as the cold rolls in. An excellent choice for first-timers and seasoned growers alike, with the RHS Award of Garden Merit to prove its garden class.

Growing Guide

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. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

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.
