Tall plants become covered along the stem with numerous, tight, dark green sprouts, and in mild winters the plants can safely overwinter in the ground—the sprouts can then be harvested as needed until January.

Its strength lies in its uniformity: the sprouts are set densely and evenly along the entire height of the stem, well closed and compact, so they do not fall apart during cooking. The outer leaves are dark green and tightly attached, protecting the sprouts from damage.\u003c\/p\u003e\u003cp\u003eIts greatest advantage, however, is its frost resistance. Groninger withstands winter cold with little loss and, in mild winters, can remain in the bed until January, serving as a natural “storage unit” for fresh vegetables. Frost actually improves the flavour: starch changes into sugars, while the characteristic bitterness becomes milder.\u003c\/p\u003e\u003ch3 style=\"color: #5C3727; margin-top: 1.5em; margin-bottom: 0.5em;\"\u003eGrowing step by step\u003c\/h3\u003e\u003cp\u003e\u003cstrong style=\"color: #656B39;\"\u003eSowing (April, in a seedbed or under cover):\u003c\/strong\u003e sow the seeds in trays, plug trays or a seedbed at a depth of 1–1.5 cm, at a temperature of 15–20°C. Germination occurs after 5–8 days. Grow the seedlings in cool conditions (12–16°C) and in full light so they remain sturdy.\u003c\/p\u003e\u003cp\u003e\u003cstrong style=\"color: #656B39;\"\u003ePricking out:\u003c\/strong\u003e prick out seedlings from trays at the first true-leaf stage into 7–8 cm pots; seedlings from a seedbed can be transplanted directly to their final position. Seedlings are ready for planting out when they have 5–6 leaves and are approximately 5–6 weeks old.\u003c\/p\u003e\u003cp\u003e\u003cstrong style=\"color: #656B39;\"\u003ePlanting out (late May – early June):\u003c\/strong\u003e plant deeply, up to the first leaves, with spacing of 40–50 × 40–50 cm, in a sunny position and fertile, humus-rich soil with a neutral or slightly alkaline reaction (pH 6.5–7.5). Brussels sprouts need calcium and stability—firm the soil around the plants, as the tall stems can easily topple.\u003c\/p\u003e\u003cp\u003e\u003cstrong style=\"color: #656B39;\"\u003eCare:\u003c\/strong\u003e water regularly and fertilise with nitrogen until July, then use only potassium and phosphorus—nitrogen late in the season produces loose sprouts. Earth up the stems and support tall plants. Around late September or early October, you can pinch out the growing tip, which speeds up sprout development. Harvest from the bottom upwards, breaking off mature sprouts 2–4 cm in diameter.\u003c\/p\u003e\u003ch3 style=\"color: #5C3727; margin-top: 1.5em; margin-bottom: 0.5em;\"\u003eUses\u003c\/h3\u003e\u003cp\u003eGroninger Brussels sprouts are a \u003cstrong\u003ewinter kitchen\u003c\/strong\u003e vegetable: steam them, \u003cstrong\u003eroast\u003c\/strong\u003e them whole with olive oil and garlic, fry them in butter with bacon, or add them to soups and casseroles. Sprouts exposed to frost are sweeter and milder, so even sceptics enjoy them. They freeze very well after brief blanching. In the garden, they occupy a bed for a long time, but in return they produce a crop when most other vegetables have long since finished.\u003c\/p\u003e\u003ch3 style=\"color: #5C3727; margin-top: 1.5em; margin-bottom: 0.5em;\"\u003eGardener’s tip\u003c\/h3\u003e\u003cdiv style=\"background-color: #f5f3ee; border-left: 4px solid #656B39; padding: 12px 16px; margin: 1em 0;\"\u003e\u003cp style=\"margin: 0;\"\u003eDo not rush the harvest—the tastiest Groninger sprouts are harvested after the first light frosts of a few degrees, when the frost has “sweetened” the leaves. If severe winter weather is forecast, pull up the entire plants with their roots and place them in sand in a cool cellar—the sprouts will continue to mature and remain fresh for several more weeks.\u003c\/p\u003e\u003c\/div\u003e\u003ch3 style=\"color: #5C3727; margin-top: 1.5em; margin-bottom: 0.5em;\"\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\u003ctbody\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eLatin name\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003eBrassica oleracea var. gemmifera\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eVariety\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003eGroninger\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eSprout colour\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003edark green\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003ePosition\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003esunny, fertile soil rich in calcium\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eSeasonality\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003ebiennial plant (grown as an annual)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eSowing time\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003eApril (in a seedbed or under cover)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003ePlanting-out time\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003elate May – early June\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eHarvest time\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003eNovember – January\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eSpacing\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003e40–50 × 40–50 cm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eNet weight\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003e1.00 g (~300 seeds)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eSeries\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003eTraditional\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003cth style=\"background-color: #5C3727; color: #fff; text-align: left; padding: 8px 12px; width: 40%;\"\u003eProducer\u003c\/th\u003e \u003ctd style=\"padding: 8px 12px; border-bottom: 1px solid #e5e5e5;\"\u003eW.
