In Ireland, St. Patrick's Day is the traditional day to plant peas and potatoes. Well you can grow your own garden peas in your backyard.
Peas require soil that is loose and loamy.Choose a spot that gets full sun. Sow peas directly in the garden. Plant the seeds an inch deep, 3 to 4 inches apart, in rows about 3 feet apart. Install supports for peas - and start guiding the vines upward as soon as they're long enough to climb. (Im having a hard time doing this as the plant constantly slides off of the supports) :( Water them regularly, they dont like too much water.
