Up to 100 days. Brussels Sprouts can be grown in colder climates, and the crop is very tolerant of frost. While the sprouts can take up to one hundred days to reach maturity, they make great crops to grow during the winter and colder months of the year. Brussels Sprouts have been cultivated since as early as the 1500’s, and have a strong and bitter taste, similar to that of cabbage.

Brussels Sprouts do best in cold climates, and in moist soil. Organic matter can help the seeds to grow, and this crop will find the most success in full sun, or as much as possible. Sow the seeds half an inch deep, with eighteen to twenty four inches between plants, and thirty inches between rows. As the Brussels Sprouts are growing, the soil will need to remain moist, and will need one inch of water each week. The sprouts can be harvested when they are firm and one to two inches in diameter. To harvest, twist the sprouts until they become separated from the plant. If you would like to harvest all the sprouts at the same time, you can force them to mature simultaneously by cutting off the top of the plant three weeks before you want to harvest.
