Though you don't have to, inoculating peas your with a legume inoculant will give you a bigger pea yield and healthier plants. Also, for faster germination, you can soak your peas in water overnight and then while they are still wet, shake them in a bag with the inoculant.
Sprinkle peas generously and evenly onto surface of soil. With the flat part of your hand, press them onto the surface of the soil. Then add an additional 1- 2 inches of soil on top. Make sure not to add more soil than that, or the peas might have trouble germinating.
You'll want to keep your soil moist, not wet and be sure that your peas are getting full sun.
