by

Creating a successful vegetable garden in Zone 4 requires understanding the seasonal planting schedule. Zone 4 experiences cold winters and short growing seasons, making timing crucial for a bountiful harvest. This calendar provides guidance on when to plant various vegetables throughout the year.

Understanding Zone 4

Zone 4 is characterized by minimum winter temperatures between -30°F and -20°F (-34°C to -29°C). Growing seasons are typically 90 to 120 days, depending on the crop. Knowing your zone helps tailor planting schedules to ensure crops have enough time to mature before the first frost.

Spring Planting (March – May)

  • March: Start seeds indoors for tomatoes, peppers, and eggplants.
  • April: Direct sow peas, spinach, radishes, and lettuce outdoors.
  • May: Transplant seedlings of broccoli, cabbage, and cauliflower outdoors after the last frost.

Summer Planting (June – August)

  • June: Plant heat-tolerant crops such as beans, corn, and cucumbers directly outdoors.
  • July: Sow successive crops of beans and squash for extended harvest.
  • August: Start seedlings indoors for fall crops like broccoli and cabbage.

Fall Planting (September – November)

  • September: Direct sow carrots, beets, and turnips.
  • October: Transplant hardy greens such as kale and spinach outdoors.
  • November: Prepare the garden for winter by mulching and covering crops.

Winter Preparations (December – February)

During winter, focus on planning and seed starting indoors. Protect winter crops with row covers or cold frames. Use this time to order seeds and prepare soil for the upcoming planting season.

Tips for Success in Zone 4

  • Use frost dates to determine the exact planting times in your area.
  • Start seeds indoors early to extend the growing season.
  • Utilize season extenders like cold frames and row covers.
  • Practice crop rotation to maintain soil health.

With careful planning and timely planting, gardeners in Zone 4 can enjoy a diverse and productive vegetable garden throughout the year. Keep this calendar handy to maximize your harvests and enjoy fresh, homegrown vegetables all season long.
