Brussel sprouts are a cool-season vegetable that can withstand cold temperatures, making them a great option for gardeners who want to extend their growing season. But can brussel sprouts overwinter? The answer is yes, with proper care and protection, brussel sprouts can survive the winter months and produce a bountiful harvest the following spring.
Understanding Brussel Sprout Hardiness
Brussel sprouts are classified as a hardy vegetable, meaning they can tolerate temperatures as low as 20°F (-6.7°C). However, young plants are more susceptible to frost damage, so it’s important to take steps to protect them during the early stages of growth.
Preparing Brussel Sprouts for Winter
To prepare your brussel sprouts for winter, follow these steps:
1. Choose Cold-Hardy Varieties: Select varieties that are known for their hardiness, such as ‘Long Island Improved’ or ‘Jade Cross‘.
2. Plant Early: Start your brussel sprouts seeds indoors 6-8 weeks before the last spring frost. Transplant seedlings outdoors when they have developed their first set of true leaves.
3. Provide Adequate Spacing: Plant brussel sprouts with enough space between plants to allow for proper air circulation and reduce the risk of disease.
4. Fertilize Regularly: Feed your brussel sprouts every 4-6 weeks with a balanced fertilizer to promote healthy growth and development.
5. Water Deeply: Water your brussel sprouts regularly, especially during dry spells. Deep watering encourages deep root growth, which helps plants withstand cold temperatures.
Protecting Brussel Sprouts from Frost
As temperatures begin to drop in the fall, take steps to protect your brussel sprouts from frost:
1. Row Covers: Cover your brussel sprouts with row covers or floating row covers to protect them from frost and wind.
2. Mulching: Apply a layer of mulch around your brussel sprouts to insulate the soil and protect the roots from freezing.
3. Cold Frames: If you live in a particularly cold climate, consider using cold frames to provide additional protection for your brussel sprouts.
Overwintering Brussel Sprouts in the Ground
In milder climates, brussel sprouts can be overwintered in the ground. To do this:
1. Choose a Protected Location: Select a spot in your garden that is sheltered from the wind and receives full sun.
2. Prepare the Soil: Amend the soil with compost or manure to improve drainage and fertility.
3. Plant Deeply: Plant your brussel sprouts seedlings deeply, about 2-3 inches below the soil surface.
4. Mulch Heavily: Apply a thick layer of mulch around your brussel sprouts to protect the roots from freezing.
5. Water Regularly: Water your brussel sprouts regularly, especially during dry spells.
Overwintering Brussel Sprouts in a Greenhouse or Cold Frame
If you live in a cold climate, you can overwinter your brussel sprouts in a greenhouse or cold frame:
1. Choose a Suitable Structure: Select a greenhouse or cold frame that is large enough to accommodate your brussel sprouts plants.
2. Prepare the Soil: Fill the greenhouse or cold frame with a well-draining potting mix.
3. Plant Your Brussel Sprouts: Transplant your brussel sprouts seedlings into the potting mix, spacing them according to the recommended spacing for your variety.
4. Water and Fertilize: Water your brussel sprouts regularly and fertilize them every 4-6 weeks with a balanced fertilizer.
5. Maintain Proper Temperature: Keep the temperature in the greenhouse or cold frame between 35°F and 50°F (1.7°C and 10°C).
Harvesting Overwintered Brussel Sprouts
Overwintered brussel sprouts can be harvested in the spring when the sprouts are firm and have a deep green color. To harvest, simply twist or cut the sprouts off the stem.
In a nutshell: Reap the Rewards of Overwintering Brussel Sprouts
With proper care and protection, brussel sprouts can successfully overwinter and produce a bountiful harvest the following spring. By following the steps outlined in this guide, you can extend your growing season and enjoy fresh, delicious brussel sprouts throughout the year.
