When to pull potatoes

[Flunky]

I put my maris piper main crop in on march 13th. i have had a look and they seem ok. What sort of size am I looking for ?

The plant I checked had a lot of medium sized potatoes and some real small ones. How do I go about harvesting these ?

Thanks in advance.

From mid- August. When the haulms die down.

I'm with Tim on this one although I don't know about mid August, that can be dependent on where you are and when you planted them, but I agree the dead/dying tops are the indicator.
