When to Plant Peas in Seattle: A Guide for Emerald City Gardeners
In Seattle, the best time to plant peas is in early spring, typically from late February to early April, as soon as the soil is workable. You can also plant peas for a fall harvest in late summer, around late July to early August. This allows them to mature before the first hard frost.
Spring Planting: Beating the Seattle Chill
Seattle’s mild winters mean you can often get a head start on spring planting. The key is to watch the soil temperature. Peas germinate best when the soil is consistently above 40°F (4°C). Avoid planting if the ground is still frozen or waterlogged. You can amend the soil with compost to improve drainage and warm it up faster.
Popular pea varieties for spring planting in Seattle include ‘Oregon Sugar Pod II’, ‘Cascadia’, and ‘Little Marvel’. These are known for their cold tolerance and early maturity.
Fall Planting: Extending the Harvest
For a fall pea harvest, aim to plant in late July or early August. This gives the peas enough time to mature before the cooler temperatures and shorter days of autumn arrive. Keep in mind that fall-planted peas may not be as productive as those planted in the spring, but they can still provide a delicious late-season crop.
Choose varieties with shorter maturity times for fall planting to ensure a successful harvest. Protect young plants from extreme heat with shade cloth if necessary.
Soil Preparation and Planting Tips
Peas prefer well-drained soil that is rich in organic matter. Amend your soil with compost or well-rotted manure before planting. Sow seeds directly into the ground about 1 inch deep and 1-2 inches apart. Provide a trellis or other support for climbing pea varieties.
