In USDA Zone 8, you should sow peas in late August through September for a fall crop to avoid the heat of summer and the intensity of the first frost.

For a spring crop, you can plant peas in mid to late winter, around January to March, when soil temperatures are cool and stable, typically 4-6 weeks before the last frost.

Timing for Zone 8

Fall/Winter Planting: This is often the preferred time for growing peas in warmer zones like Zone 8 because it avoids the extreme heat that can damage plants.
- August/September: Direct sow peas for a fall harvest to take advantage of the declining temperatures.
- Late Winter/Early Spring: You can also sow peas in the late winter or early spring, around February to March, to harvest before it gets too hot in the summer.

Key Factors:
- Heat Sensitivity: Peas need cool temperatures to grow well and are sensitive to heat.
- Soil Temperature: Wait for the soil to reach at least 45-50°F (7-10°C) before sowing to ensure good germination.
- First Frost Date: For fall planting, aim to sow about 10-12 weeks before your first expected frost.

Tips for Success

Provide Support: Use pea sticks or netting for support as the plants grow.

Well-Drained Soil: Ensure your soil is well-drained, as wet conditions can cause seeds to rot.

Expect a Smaller Harvest: Fall pea crops may produce smaller yields compared to spring plantings.
