How to grow Brussel Sprouts Groninger Seeds
Brussel Sprouts Groninger is a frost-tolerant variety, and the flavor of the sprouts is said to improve with cooler weather.
Planting Brussel Sprout Seeds
Sow seeds indoors 4–6 weeks before the last frost date in spring, or direct sow outdoors in late spring or early summer once the danger of frost has passed.
Sowing & Germination
Use well-draining seed trays or pots filled with seed starting mix. Sow seeds about 0.5 cm deep. Expect seedlings to emerge in 7–14 days.
Seedling Care
Provide seedlings with plenty of bright, indirect sunlight. Once they have 4–6 true leaves, thin them out to the strongest seedling per pot.
Plants should reach maturity after approximately 100 days.
Transplanting
Harden off seedlings gradually before transplanting them outdoors 1–2 weeks after the last frost date.
General Care
Choose a sunny location with well-drained, fertile soil. Water regularly, especially during hot weather, keeping the soil consistently moist but not soggy.
Harvesting
Brussel Sprouts Groninger are ready to harvest when the individual sprouts reach a size of 2.5–5 cm in diameter and feel firm to the touch.
Harvest them from the bottom of the stalk upwards, starting with the largest and firmest ones. You can continue harvesting over several weeks as new sprouts mature.
Additional Tips
Consider planting companion plants like beans, carrots, or lettuce to attract beneficial insects and deter pests.
Keep an eye out for common pests like cabbage worms and aphids, and use organic methods like neem oil or handpicking to control them.
