Feldon, the Oregon Sugar Pods are snow peas. I guess I'm a little confused by the last paragraph of your post
. I still think your OSP shut down early. You should have had way more than three quarts for a 4'x4' area and longer production. My planting area is 3- 1/2 feet long and 4 inches wide and I got over 4 gallons of pea pods. I will post a pic tonight of my spent vines that are paritially ripped out so you can see my set up anyway. The plants are dead now
.
I just tried 'Dual' this year and wasn't too impressed by it. I will grow it again next year since I have more seeds before I write it off. It is a shelling pea that did not like warm temps at all and produced a very small crop. 'Wando' has done much better for me.
I haven't grown the sugar snaps in a while because I have some organic farmer friends that grow them so I just buy in bulk from them.
