Don't forget, peas benefit from a good soak before planting. I presoak my peas in water for 6-12 hours. Before planting (1 inch deep and 3 inches apart) I drain them and coat them with pea/bean inoculant. Inoculants are bacterium that aid legumes in fixing nitrogen from the air. This nitrogen eventually ends up in the soil, feeding other hungry plants. In my experience, peas germinate more reliably when inoculated.
Since peas are such great nitrogen fixers they have many happy garden companions. Peas, radishes and lettuces do well together, all of them finishing early enough that something else can follow. Corn benefits from the extra nitrogen boost, as do carrots and cucurbits. Just be sure to keep onions and other alliums out of the same bed.
Happy Easter to those who celebrate, and Happy Spring to all! Get out there and plant those peas!
