Snow Pea Advice
Take Time to Trellis
While some varieties are touted as bush types or even "self-trellising," snowpeas are essentially vining plants that are most manageable when they're climbing. So plant them next to a trellis, and the pods will hang there waiting for you to remove them.
"If you grow in double rows, you can simply erect one trellis between the rows," notes Oklahoma State's Dr. Kahn, who adds that he prefers trellises made from nylon netting (attached to stakes) rather than metal because the nylon doesn't rust or heat up as metal can.
Once your snowpeas begin producing, harvest them regularly and you'll increase your total yield. That's right, the more you pick the more the plant will produce.
I've heard that some people grow more snowpeas than they can eat right away. This has never happened to me, because many that I grow never make it into the house—I like to munch them raw while I'm in the garden. But if you do have a surplus of snowpeas, you can store them in the freezer. Simply spread them out on cookie sheets and put them in the freezer. When they've frozen, pour them into a resealable plastic bag.
