I sowed a row of 1st early Red Duke of York for the first time on 16th March and one plant is already flowering. I get the impression from reading around internet discussion groups that 10 – 13 weeks is pretty standard for this strain. Mine are currently 9 weeks since sowing and only about 4 weeks since emergence from the ground.
Is harvesting 1st earlies before the end of May usual, normal in early warm springs or abnormally early (i.e. I should leave them in the ground for 3 or 4 more weeks)?
