Understanding Carrot Growing Seasons

Carrots are a cool-season crop, and the timing of their planting in Minnesota is crucial for a successful harvest. Here are some key factors to consider:

  • Last Spring Frost: The last spring frost in Minnesota usually occurs in mid May. It’s essential to plant carrots after this date to avoid frost damage to young plants.
  • First Fall Frost: The first fall frost in Minnesota typically happens in late September to early October. This marks the end of the growing season for many plants, including carrots.
  • Ideal Growing Temperature: Carrots thrive in cooler temperatures and are often grown as a spring or fall crop. Their ideal soil temperature for germination is between 50°F and 85°F (10°C to 30°C).

Using Grow Bags for Carrot Cultivation

Grow bags provide an innovative solution to the challenges of carrot cultivation in Minnesota. These bags offer several advantages:

  • Mobility: Grow bags are portable, allowing you to move them to find the best sun exposure or to protect your carrots from adverse weather conditions.
  • Temperature Control: The soil in grow bags warms up more quickly in the spring, enabling earlier planting, and can be moved indoors to extend the growing season in the fall.
  • Soil Quality: You have control over the soil quality in grow bags, ensuring optimal conditions for seed germination and carrot growth.
  • Space Efficiency: Grow bags are ideal for small spaces, such as balconies, patios, or small gardens, making them suitable for urban gardeners.

When to Plant Carrots in Grow Bags

Using grow bags gives you greater control over your carrot planting schedule. Here’s a month-by-month guide on when to plant carrot seeds in Minnesota using grow bags:

1. April: Early Spring Planting

  • As soon as the last spring frost has passed (usually late April to early May), you can start planting carrot seeds in grow bags. The warmer soil inside the bags allows for an earlier start compared to planting directly in the ground.
  • Select carrot varieties that mature quickly, such as ‘Nantes’ or ‘Parisienne.’ These varieties are perfect for early spring planting.

2. May: Late Spring Sowing

  • Continue sowing carrot seeds in grow bags throughout May. This staggered planting ensures a continuous harvest through the summer and into the fall.

3. July: Preparing for Fall Harvest

  • In early July, consider sowing another round of carrot seeds in grow bags. These carrots will be ready for harvest in the fall, extending your carrot season.

4. August: Preparing for Winter Storage

  • For those interested in overwintering carrots, early August is the time to sow seeds in grow bags. These carrots can be left in the bags and harvested throughout the winter.

Tips for Successful Carrot Planting in Grow Bags

To maximize the success of your carrot planting in grow bags, consider the following tips:

  • Soil Preparation: Use a high-quality potting mix that is well-draining. Carrots prefer loose, sandy soil. Mixing sand or perlite into your potting mix can improve drainage.
  • Proper Watering: Keep the soil in grow bags consistently moist but not waterlogged. Carrots require even moisture for good root development.
  • Thinning: After your carrot seedlings emerge, thin them to ensure proper spacing. Crowded carrots may produce misshapen roots. Thin to about 2-3 inches apart.
  • Mulching: Adding a layer of mulch over the soil in your grow bags helps conserve moisture and regulates soil temperature. Mulch also helps prevent soil from drying out too quickly.
  • Pest and Disease Control: Regularly inspect your carrot plants for signs of pests or diseases. Common pests for carrots include carrot fly and aphids. Keep your garden clean and practice crop rotation to reduce the risk of disease.
  • Companion Planting: Planting carrots alongside companion plants like onions or chives can help deter pests.
  • Protection: In late summer or early fall, cover your carrot plants in grow bags with row covers to protect them from cold temperatures and frost. This allows you to continue harvesting into the fall and even early winter.

Harvesting and Storing Carrots

Carrots are typically ready for harvest 60 to 80 days after planting, depending on the variety. Here’s how to harvest and store your homegrown carrots:

  • Harvest: Gently pull the carrots from the soil. Use a trowel or fork if they are difficult to remove. Be careful not to damage the roots.
  • Cleaning: Remove excess soil by gently brushing or shaking the carrots. Do not wash them until you’re ready to use them. Washing can promote spoilage during storage.
  • Storage: Store your harvested carrots in a cool, humid place. A root cellar or a refrigerator’s crisper drawer works well. Carrots can be stored for several months under the right conditions.
  • Preservation: Carrots can also be preserved by blanching and freezing, canning, or pickling.


Growing carrots in Minnesota can be a rewarding experience with the use of grow bags, which provide versatility and control over planting dates. By understanding the state’s growing seasons and the benefits of grow bags, you can enjoy a continuous harvest of these crisp and nutritious root vegetables. Whether you’re looking to savor the early spring sweetness or extend your harvest into the fall and winter, grow bags provide a practical solution for cultivating delicious homegrown carrots in the Land of 10,000 Lakes.
