- Hardy biennial harvested at the end of the first season.
- Enlarged buds at the base of leaves, called sprouts, are harvested during first season of growth.
- Medium height, 2- 3 ft.
- Spring plantings are usually not successful. This vegetable needs a long season of growth and cool weather as the buds mature.
- For fall harvest, start seeds in mid-June to transplant into the garden in late July-early August. Space 18-24” apart, with minimum row spacing of 24”. Spacing within a wide row is 18-24”. • First harvest is 85-100 days from transplanting, 130 days from seed. Lowest buds mature first. Harvest when they are 1-2” in diameter. Remove the leaves at the base of the buds you harvest.
Plant seeds 1/4”-1/2” deep. Germination is best at 70-80 °F and seedlings will appear in about 5 days. Grow the seedlings a bit cooler, at 60-70 °F. They will be ready for transplanting in 4-5 weeks. You may also be able to purchase transplants. If you try a spring planting, put transplants out early, in March or early April. Summer planting for fall harvest are more common. Have plants in the ground by early July in northern Indiana, by mid-August in southern Indiana. Practice crop rotation. Do not plant the same area with a cole crop two years running.
