I mixed my sugar snap pea into my perennial bed along the fence and I also planted some in the hidden garden at the end of the alley. I have invested a lot of energy (lasagna garden with an annual mulching of chopped up leaves and composted horse bedding) in creating some terrific soil in my perennial bed, so planting was easy:
First, I made a hole with my finger. Peas need to be planted about 1" deep. The distance between the tip of my finger and my first knuckle is about 1", so making a hole at the correct depth with my finger is easy.
Then I dropped a pea in the hole and covered it up.
In my perennial bed, the peas will climb the fence. In the hidden garden, they will climb some tree branches that I scavenged from the lot.
