Pea question for DD and of course all other people on the site..

I have pulled all my early dwarf - Hatif d'Annonay peas as they were basically finished and I want the space for beetroot. I can use some that are green and just OK for eating but the others are yellowing to being a bit greenish and the pods are starting to go limp and shrivel and feel like leather. i.e. - past their eat by date..

Can I let these older ones dry in the pod and keep them for seed or should I have left the plants to all go dry before picking the last of them for seed?

DD - the Stokesley you sent me are doing well and I will keep some seed from these as well so hence the question above as well!!
