September Planting Guide for Zone 5: Extend Your Harvest and Prepare for Fall Beauty


As summer gradually gives way to the cooler temperatures of autumn, there’s still plenty you can do in your Zone 5 garden to keep it vibrant and productive. While the growing season might be winding down, September offers a golden opportunity to sow new seeds and plant some cool-season crops that thrive in the crisp fall air. In this blog post, we’ll explore a variety of options for what you can plant in your Zone 5 garden to make the most of this transitional month.

1. Cool-Season Vegetables:
As the weather cools down, many cool-season vegetables thrive in Zone 5 gardens:

  • Lettuce: Plant various lettuce varieties for crisp salads well into fall.
  • Spinach: Sow spinach seeds for a nutrient-packed addition to your garden beds.
  • Kale: This hardy green shines in cooler temperatures and even improves in flavor after a light frost.
  • Radishes: Quick-growing radishes can be harvested in just a few weeks.
  • Carrots: Select varieties with shorter maturity times to enjoy fresh carrots later in the season.
  • Beets: Both the roots and greens of beets can be enjoyed, making them a versatile choice.

2. Garlic Planting:
September is garlic planting time, allowing the cloves to establish roots before winter for a bountiful harvest next summer.

3. Herbs for Spring:
Planting perennial herbs now ensures they’ll establish their root systems over the winter and thrive next spring:

  • Chives
  • Thyme
  • Oregano
  • Sage
  • Lavender
  • Mint (Consider planting in a container to control its growth.)

4. Flower Bulbs for Spring Color:
Plan for a colorful spring display by planting flower bulbs in September:

  • Tulips: These classic blooms add elegance to any garden.
  • Daffodils: Reliable and deer-resistant, daffodils are a spring garden favorite.
  • Crocuses: Plant these early bloomers for a burst of color in late winter or early spring.

5. Cover Crops for Soil Health:
Consider planting cover crops like winter rye or clover to enrich your soil and prevent erosion during the winter months.

6. Fall-Blooming Plants:
Add bursts of color to your garden with fall-blooming plants:

  • Mums: These vibrant flowers bring autumnal hues to your landscape.
  • Pansies: With their cheerful faces, pansies thrive in cooler weather.

7. Transplants for Fall Harvest:
You can also transplant cold-hardy seedlings from nurseries to enjoy a late fall harvest:

  • Broccoli
  • Cabbage
  • Cauliflower
  • Kohlrabi

Remember to stay aware of your local frost dates, as they can vary within Zone 5. Consider using season extenders like row covers or cold frames to protect your plants from early frost. Additionally, ensure your new plantings receive consistent moisture to help them establish before winter sets in.

September in Zone 5 doesn’t signal the end of your gardening journey; rather, it’s a chance to embrace the beauty of fall and continue reaping the rewards of your efforts. Whether you’re enjoying the last harvests of summer or sowing the seeds for a colorful spring, your Zone 5 garden has plenty to offer throughout September. Take advantage of the cooler temperatures and prepare your garden for a vibrant transition into the next season.
