Choosing the Right Varieties for March Planting in Zone 5

by

March is a critical month for gardeners in Zone 5, as it marks the beginning of the planting season. Selecting the right varieties to plant during this time can significantly influence the success of your garden. Understanding the climate, soil conditions, and the specific needs of each plant will help you make informed choices.

Understanding Zone 5 Climate

Zone 5 experiences cold winters with average minimum temperatures ranging from -20°F to -10°F. Spring arrives later compared to warmer zones, and the risk of frost persists into late April or early May. This means that early planting should focus on hardy varieties that can withstand cooler temperatures.

Choosing Hardy Vegetables

For March planting, select vegetable varieties known for their cold tolerance. These include:

  • Peas: Sugar snap and shelling peas are excellent choices.
  • Spinach: Hardy and quick to mature, ideal for early planting.
  • Radishes: Fast-growing and tolerant of cool weather.
  • Lettuce: Leaf varieties such as ‘Black-Seeded Simpson’ thrive in early spring.
  • Broccoli: Plant hardy transplants or seeds directly outdoors.

Choosing specific varieties can improve your success rate. Here are some popular options:

  • Peas: ‘Green Arrow’, ‘Super Sugar Snap’
  • Spinach: ‘Bloomsdale Long Standing’, ‘Baby’s Leaf’
  • Radishes: ‘Cherry Belle’, ‘French Breakfast’
  • Lettuce: ‘Black-Seeded Simpson’, ‘Red Romaine’
  • Broccoli: ‘Calabrese’, ‘Packman’

Planting Tips for March

To maximize success, follow these tips:

  • Start seeds indoors if the weather is still too cold.
  • Use cold frames or row covers to protect young plants from late frosts.
  • Ensure well-draining soil with ample organic matter.
  • Water consistently, keeping the soil moist but not waterlogged.
  • Monitor weather forecasts regularly to prevent frost damage.

Conclusion

Choosing the right varieties for March planting in Zone 5 involves understanding the climate and selecting hardy, cold-tolerant plants. By starting early with suitable varieties and protecting your garden from late frosts, you can set a strong foundation for a productive growing season.
