Early March: What to Sow Directly into the Ground in Zone 3

by

As winter begins to fade in Zone 3, gardeners start preparing for the upcoming planting season. Early March is a crucial time to sow certain crops directly into the ground to ensure a bountiful harvest later in the year. Knowing which plants thrive when sown directly can make all the difference in your garden’s success.

Understanding Zone 3

Zone 3 is characterized by its cold climate, with average minimum temperatures ranging from -30°F to -40°F. Short growing seasons and late frosts mean that timing is essential for successful planting. Selecting hardy crops that can withstand these conditions is vital for early spring planting.

What to Sow Directly into the Ground in Early March

  • Peas: Varieties like sugar snap and shelling peas are cold-hardy and can be sown as soon as the soil can be worked. They prefer cooler temperatures and will produce early crops.
  • Carrots: Sow carrot seeds directly into prepared soil. Choose short or Nantes varieties suited for cooler climates.
  • Radishes: Radishes are quick-growing and tolerate cold soil. Sow multiple times for a continuous harvest.
  • Turnips: Hardy and fast-growing, turnips can be sown directly into the ground in early spring.
  • Spinach: Cold-tolerant and fast-growing, spinach can be sown early for an early harvest.
  • Kale: Sow kale seeds directly into the soil. It is frost-resistant and can be harvested over a long period.
  • Mustard Greens: These greens thrive in cool weather and can be sown directly into the ground.

Preparation Tips for Early March Planting

Before sowing, ensure the soil is workable and not frozen. Incorporate compost to improve soil fertility and drainage. If the soil is too wet or frozen, wait for a few warm days to allow it to dry out and thaw. Using cold frames or mini hoop tunnels can extend the planting window and protect young seedlings from late frosts.

Additional Considerations

Keep an eye on weather forecasts. Frosts can still occur in early March, so be prepared to cover young plants with row covers or blankets during cold nights. Regularly check soil temperature; most direct-sown crops prefer soil temperatures above 40°F for optimal germination.

Conclusion

Early March is an excellent time to start planting certain hardy vegetables directly into the ground in Zone 3. Proper preparation, choosing the right crops, and protecting young plants from late frosts will set the foundation for a successful growing season. Happy planting!
