Thanks for your comments Di and congratulations on all that bounty.
As for the pests, they have at least as many of these in general but where I was the onion fly was not bad. Carrot root fly is endemic, less bad in summer than in autumn so cover with mesh by August for winter carrots.
I remember some pea moth but sowing in Feb or March helped have half the harvest before they established.
Leek moth was terrible so worth meshing them as soon as planted.
Vas-y!
