I've never put peas with tomatoes. I've never seen them listed as companions before either.

I know peas are good with corn and beans. Interesting idea. I would like to know how it does for you. Post some results!

I am planning to put the tomatoes right in front of the peas this year also, and in fact trellis them on the same pea supports (brush). I'll hold the tomato starts out as long as possible, hopefully til second week in june. Here the peas are mostly done by july 1st. The rotting pea-roots should release some food for the toms at the right time.

I don't think your plan of extending the pea-season with tomato-shade will work. It'll be too much shade plus the tomato roots will be sucking what life is left out of the pea-plants.

Second.

However, at least here in S. Oregon, the you can seed snow-peas in late fall / early winter, they can take the worst of what mother nature throws at them, especially if they're protected to one side by a fence. Then around late March / early April, while we still have a few weeks before the last frost date, people usually till the pea plants into the ground, which both adds organic matter in and also by killing the plants, releases the nitrogen that have been fixed onto their root nodes for the past 3 months, putting food in for Tomatoes, Peppers, Corn or anything else you want to plant there.
