How to Grow Brussels Sprouts in Virginia

Climate and Growing Conditions

Brussels sprouts are cool-weather vegetables that thrive in regions with moderate temperatures. Virginia’s climate, with its distinct seasons, provides a good growing environment for Brussels sprouts, especially in the fall when temperatures cool down. Brussels sprouts prefer temperatures between 60-70°F, making the end of summer into fall the ideal time to grow them in Virginia.

Best Time to Plant:
In Virginia, Brussels sprouts are best planted in mid-to-late summer (July to August), giving them enough time to mature during the cooler fall months. Brussels sprouts need a long growing season, typically around 80 to 100 days, so starting them early enough ensures they will be ready before winter frosts.

Soil Preparation

Brussels sprouts require rich, well-drained soil. Before planting, it’s essential to prepare the soil to meet these conditions:

  • Soil pH: Aim for a slightly acidic to neutral soil with a pH between 6.0 and 7.5.
  • Soil Amendments: Incorporate organic matter like compost or well-rotted manure into the soil. This enriches the soil with nutrients, particularly nitrogen, which Brussels sprouts need for optimal growth.
  • Mulching: After planting, applying mulch around the base of the plants helps retain moisture and regulate soil temperature.

Planting

You can either sow Brussels sprouts seeds directly into the garden or start them indoors 6 to 8 weeks before planting out. Once seedlings are about 4-6 weeks old and have grown sturdy, they can be transplanted.

Spacing:
Plant Brussels sprouts about 18-24 inches apart in rows, with rows spaced 30 inches apart to ensure they have ample room to grow. The plants grow tall (2-3 feet), so leaving enough space between them promotes airflow and reduces disease risk.

Watering and Care

  • Watering: Brussels sprouts need consistent moisture, especially during hot spells in late summer. Aim for about 1-2 inches of water per week. Be careful not to overwater, as soggy soil can lead to root rot.
  • Fertilization: Brussels sprouts are heavy feeders. Once the plants are established, use a balanced fertilizer (such as 10-10-10) every 3-4 weeks. A nitrogen-rich fertilizer can also help encourage leafy growth early on.
  • Pest Control: Common pests in Virginia that affect Brussels sprouts include aphids, cabbage worms, and flea beetles. Regularly inspect your plants for signs of pests and use insecticidal soap or neem oil as necessary.
  • Staking: As the plants grow taller, they may need staking for support, especially in windy areas.

Harvesting

Brussels sprouts mature from the bottom of the plant upward, so you can begin harvesting the lower sprouts first. They are ready to be picked when they are about 1-2 inches in diameter and firm to the touch.

Tip: A light frost can improve the flavor of Brussels sprouts, making them sweeter, so don’t be afraid to leave them in the garden a bit longer if frosts are forecast in late fall.

Conclusion

Growing Brussels sprouts in Virginia is a rewarding process that, with proper care and timing, can yield a healthy fall crop. By planting in late summer and paying attention to soil quality, watering, and pest control, you can enjoy homegrown Brussels sprouts through the cool autumn months.
