RE: they already picked it clean...now what?
I would go with some sort of mix. Like a Biologic Texas Draw or Tecomate Ultra Forage. I'm not saying that you have to buy the brand name, but get something that will regenerate and be productive throughout the season. I know you're in panic mode because all your peas are gone a week before opening day, but you need to think big picture. Have something that will be there long past the first week of the season.
