Here are the steps to seed peas:

1. Choose the type of peas you want to grow. There are many varieties of peas to choose from, including snap peas, snow peas, and shelling peas.
2. Prepare the soil. Peas prefer well-draining soil with a pH of 6.0 to 7.5. Remove any weeds and rocks, and loosen the soil to a depth of 6 inches.
3. Decide whether to seed directly or start seeds indoors. Direct seeding is done by sowing the peas directly into the soil, while starting seeds indoors involves planting the seeds in containers indoors and then transplanting them outside when they are big enough.
4. If starting seeds indoors, fill a container with potting soil and plant the seeds about an inch deep. Keep the soil moist and warm, and transplant the seedlings outside once they have grown to about 2-3 inches tall.
5. If direct seeding, plant the peas about an inch deep, spacing them about 2-4 inches apart. Cover the seeds with soil and water well.
6. Water the peas regularly, about 1-2 inches of water per week, and keep the soil moist but not waterlogged.
7. Fertilize the peas with a balanced fertilizer about once a month, or as needed. Be careful not to over-fertilize, which can damage the plants.
8. Provide support for climbing peas, such as poles, trellises, or cages.
9. Watch for pests and diseases, and take action to control them as needed.
10. Harvest the peas when they are mature and ready to eat. Snap peas and snow peas are harvested when the pods are still flat, while shelling peas are harvested when the pods have filled out and the peas inside are plump.

With these steps, you can successfully seed peas and enjoy a delicious harvest.
