Introduction to Brussels Sprouts Plants and Their Growth Cycle
Brussels sprouts plants (Brassica oleracea var. gemmifera) belong to the Brassicaceae family, which also includes cabbage, broccoli, and kale. These plants are biennial, but they are typically grown as annuals for their edible sprouts. Brussels sprouts are known for their small, compact leafy buds that resemble miniature cabbages.
Brussels sprouts are a delightful and nutritious vegetable that can be grown in your own garden. To ensure a successful harvest, it’s essential to understand the growth cycle of Brussels sprouts plants.
Understanding the growth cycle of Brussels sprouts plants is crucial for successful cultivation. By knowing the different stages of their growth and the factors that influence their production, you can optimize your gardening efforts and enjoy a bountiful harvest.
Understanding the Growth Cycle of Brussels Sprouts
Brussels sprouts plants are biennial, which means they complete their life cycle in two years. However, for practical purposes, most gardeners treat them as annuals and harvest the sprouts in their first year. Let’s take a closer look at the different stages of growth.
Stage 1: Seed Germination and Seedling Development
It all starts with the humble seed. Brussels sprouts seeds are typically sown indoors or in a greenhouse about six to eight weeks before the last expected frost date. They require a soil temperature of around 70°F (21°C) for successful germination.
Once the seeds germinate, they develop into seedlings within a couple of weeks. At this stage, they require ample light and a slightly cooler environment to prevent legginess. It’s essential to provide them with proper care, including adequate water and nutrient-rich soil, to ensure their healthy growth.
Stage 2: Transplanting and Vegetative Growth
When the seedlings have developed their second set of true leaves, they are ready for transplanting outdoors. This usually occurs around four to six weeks after germination. Before transplanting, it’s advisable to harden off the seedlings by gradually exposing them to outdoor conditions over a period of 7 to 10 days.
Once transplanted, the Brussels sprouts plants enter a phase of vegetative growth. During this stage, they focus on developing a strong root system and lush foliage. Providing them with sufficient water, regular weeding, and occasional fertilization will promote healthy growth and vigor.
Stage 3: Sprout Formation and Maturation
As the plants continue to grow, small sprouts or buds begin to form in the leaf axils of the stem. These buds gradually enlarge and develop into the Brussels sprouts we love to harvest. The sprout formation typically starts from the bottom of the plant and progresses upward.
The time it takes for the sprouts to mature depends on various factors such as the variety, weather conditions, and cultural practices. On average, it takes about 90 to 180 days from transplanting for Brussels sprouts plants to reach full maturity. However, some early-maturing varieties can produce harvestable sprouts in as little as 80 days.
Stage 4: Harvesting and Post-Harvest Care
Harvesting Brussels sprouts is a gradual process, allowing you to pick the sprouts as they reach their desired size. Start harvesting from the bottom of the plant, gently twisting or cutting off the sprouts with a sharp knife. The sprouts at the top will continue to develop as you harvest the lower ones.
It’s important to note that cold weather enhances the flavor of Brussels sprouts. Many gardeners prefer to leave the plants in the ground even after the first frost, as long as the ground is not frozen. However, if you anticipate severe freezing or want to store the sprouts for an extended period, you can harvest the entire plant and store the sprouts in a cool, dark place for several weeks.
When Do Brussel Sprouts Plants Start and Stop Producing?
Brussels sprouts are a cool-weather crop that requires cool weather to grow. They can be planted in early spring or mid- to late summer for a crop that matures in the fall. The small heads mature best in cool and even lightly frosty weather.
Brussels sprouts grow tall first and don’t start producing sprouts until they reach almost full height. Each sprout grows in the leaf axil, or joint. Sprouts begin maturing from the bottom of the plant upward.
Brussels sprout formation will begin about 50 days after planting, and sprouts will begin to ripen from the ground up after 80-90 days.
Sprouts are ready to harvest when the tiny heads are firm, green, and 1 to 2 inches in diameter. Remove sprouts by twisting them until they break away from the plant. As you remove the lower sprouts, you can also remove the yellowing leaves; the plant continues to grow upward, producing more leaves and sprouts.
Full-grown sprouts keep well on the plant in cold weather, and the plant will withstand frost and can be harvested until a hard freeze strikes
