If you want some to put in the freezer, I suggest planting Victory Freezer peas or Lincoln. Plant 5 rows ten inches apart and 25 feet long. When the plants are two inches tall you can drag a hoe between the rows and get rid of most of the weeds. These varieties will have most of the pods get ready at the same time so it is great for freezer peas.
For just some fresh eating peas plant Wando or Little Marvel. These have the harvest spread out more so you can pick over a longer period. A planting like above works well. That is a 25 foot row for each person.
