I wouldn't have thought the 2nd earlies would be ready yet, they've only been in for six weeks. In 2003 we planted Int'l Kidney in week 13 and dug up a plant in week 24 and that was too early. The MC need much longer, we planted our Sarpos in week 19, and I didn't make a note of when we dug them up - it was very late summer, I remember.
If you nip off the flowers apparently you get 10% more crop, don't know if this is true, but we do it anyway.
