Tips for Growing Kale and Other Greens in Zone 3

by

Growing kale and other greens in Zone 3 can be a rewarding experience, even with the short growing season and harsh winters. With proper planning and care, you can enjoy fresh, nutritious greens throughout the year.

Understanding Zone 3 Challenges

Zone 3 is characterized by cold temperatures, often dropping below -30°F (-34°C). This limits the types of greens that can survive outdoors during winter. Short summers mean you need to maximize your growing window and choose hardy varieties.

Choosing the Right Greens

  • Kale: A cold-hardy green that can withstand frost and even snow.
  • Spinach: Prefers cooler temperatures and can be grown early or late in the season.
  • Swiss Chard: Tolerates cold and can be harvested multiple times.
  • Mustard Greens: Fast-growing and hardy in cooler weather.
  • Arugula: Prefers cooler temperatures and matures quickly.

Planting Tips for Zone 3

Timing is crucial. Start seeds indoors 4-6 weeks before the last expected frost date. Transplant seedlings outdoors once the soil warms and the danger of heavy frost has passed. Use cold frames or row covers to extend the growing season into fall and winter.

Soil Preparation

Greens thrive in well-draining, fertile soil rich in organic matter. Amend your soil with compost before planting. Maintain a pH between 6.0 and 7.5 for optimal growth.

Caring for Your Greens

  • Watering: Keep soil consistently moist but not waterlogged.
  • Fertilizing: Use a balanced fertilizer every few weeks during the growing season.
  • Pest Control: Watch for aphids and cabbage worms; use organic controls as needed.
  • Mulching: Apply mulch to retain moisture and suppress weeds.

Extending the Growing Season

Use cold frames, hoop houses, or row covers to protect your greens from frost and extend harvest into late fall or early winter. Consider planting cold-tolerant varieties for better winter resilience.

Harvesting Tips

Harvest greens regularly to encourage new growth. Use scissors or sharp knives to pick leaves, leaving the central plant intact. For kale, harvest the outer leaves first, allowing the inner leaves to continue growing.

Final Tips for Success

Patience and proper planning are key. Start early indoors, protect your plants during cold snaps, and choose hardy varieties. With these tips, you’ll enjoy fresh greens even in Zone 3’s challenging climate.
