by

August is a critical month for gardeners in Zone 4 who want to extend their growing season and enjoy fresh greens into the cooler months. Selecting the right varieties of late-season greens can make all the difference in a successful harvest. In this article, we explore the best choices for planting late-season greens in Zone 4 during August.

Understanding Zone 4 and Its Growing Season

Zone 4 experiences cold winters with minimum temperatures often dropping below -20°F (-29°C). The growing season is relatively short, typically from late April to early October. To maximize your harvest, it’s essential to choose greens that can tolerate cooler temperatures and have a quick maturity time.

Best Late-Season Greens for August Planting

  • Spinach (Varieties: Bloomsdale, Baby’s Leaf)
  • Kale (Varieties: Winterbor, Lacinato)
  • Swiss Chard (Varieties: Bright Lights, Fordhook)
  • Mustard Greens (Varieties: Southern Giant, Red Giant)
  • Arugula (Varieties: Astro, Rocket)
  • Pak Choi (Varieties: Mei Qing Choi, Joi Choi)

Planting Tips for August

When planting late-season greens in August, consider the following tips:

  • Start seeds indoors if the weather is still hot to get a head start.
  • Prepare well-drained soil enriched with compost for optimal growth.
  • Plant seeds 4-6 weeks before the first expected frost date, which is usually around late September to early October in Zone 4.
  • Use row covers or cold frames to protect young plants from early frosts and pests.
  • Water consistently to keep the soil moist but not waterlogged.

Additional Considerations

Growing greens in late summer requires attention to temperature fluctuations. While many greens are cold-tolerant, extreme cold can damage young plants. Keep an eye on weather forecasts and be prepared to protect your crops with covers or mulch. Succession planting every few weeks can also ensure a continuous harvest into late fall.

Conclusion

August is an excellent time for Zone 4 gardeners to plant late-season greens. By choosing hardy varieties like spinach, kale, and Swiss chard and following proper planting techniques, you can enjoy fresh, nutritious greens well into the cooler months.
