Even though I’ve just planted some more peas, the last lot didn’t germinate and I’m thinking I should just go and get some more seeds. I’d really like to order them through Diggers; but I’m rapidly running out of pea weather; so I’m thinking of ducking down to the local M10 tomorrow, so I can get them planted ASAP.

With the big commercial seed companies which ones do you folks like best (better)?

Greenfeast peas are the standard winter pea and they can be purchased cheaply from fodder stores because hobby farmers use them as a cover crop. Growers Pride are selling for 99cents per packet here.
You can plant summer peas – mainly the sugar snap kind.
