last year i grew early nantes in a drum 3 feet high and autumn king in drums about 2'6" high. the nantes were fine , absolutely flawless, but the autumn king were riddled with fly  . i have read today that autumn king are probably the most susceptible of all carrots to fly  . i was planning to grow them this year about a  metre off the ground but now not sure. is there a fly resistant variety available that will stay in the ground as long as autumn king as i want to pick them fresh on Christmas day?

many thanks for replies

There are no varieties which are guaranteed not to be affected by carrot fly, I think.  Your best bet is to choose an appropriate variety which will last until the end of the year (the C word is banned here until December  ), and cover with enviromesh or similarly small mesh to prevent the fly getting through.

Last year Enviromesh was the only thing that kept my carrots free of the ***.

Have you tried Resistafly?  It's a Nantes variety that will crop in december.
