Brussels Sprout Groninger

How to sow seed: Sow in spring to harvest in winter or in autumn for harvest in late spring to autumn Nearly all brassicas should be planted in a seedbed or in modules under glass and then transferred. Sow thinly, as this reduces the amount of future thinning necessary and potential risk from pests. Cover seeds to 1.25cm (¼ to ½ inch) deep and transplant the seedlings when they are about 7cm (3in) tall. Do not allow transplants to become stunted before transplanting. Water the day before moving, and keep well-watered until established. Space plants 60 to 90cm (24 to 36in) apart in the row, or 60cm (24in) in all directions in beds. Cultivation: Brassicas are affected by a wide range of pests and diseases. Make sure the soil is adequately limed and well drained. Rotate your crops annually to avoid disease. Don't grow brassicas on the same plot more often than one year in three, as moving the crop helps avoid the build up of soil pests and diseases. Apply one side-dress application of nitrogen fertilizer when the plants are 30cm (12in) tall and water to keep the crop growing vigorously during the heat of summer. Without ample soil moisture, the crop fails. Insect control is also very important to keep the plants growing vigorously. Cultivate shallowly around the plants to prevent root damage. As the plants get taller make sure you support them so that the strong winds in winter don’t blow them over - tie them to stakes. The sprouts form in the axis of the leaves (the space between the base of the leaf and the stem above it). The old practice of pinching out the growing tip to hasten maturity is often no longer recommended, but you can do so if you wish - about three weeks before harvest, the plants are topped (the growing point removed) to speed the completion
