Yet another Christmas spud question

Apologies, I know there have been a few threads on this topic lately, and I have mooched through them for info... what I'm not sure (and sorry if it's a daft question), do I still chit them prior to putting them in?

Just picked up my seed potatoes from a local garden centre (Ulster Classic for roasties and Red Duke of York for boiled - both from JBA) and I'm wondering if there was actually time to chit or not, I believe they need to go in by mid-August latest?

Thanks in advance...

I carried mine home in a bag and popped them straight in the trench, they must be doing something cos we saw shoots yesterday. Maybe I am far to early but oh well every spuds a bonus

Mine went in two weeks ago and before you ask the name escapes me, but I will ask hubby later and I bet he says the same  

If I ask the kids the name they will just say "Christmas spuds " so thats a lost cause  

Thanks! 

I'm in two minds whether to put them in the ground and then fleece them when the weather turns, or put them in a huge container I have, 'insulate' the sides with cardboard and again fleece the tops...

we tried in tubs last year and twice bubble wrapped the side and twice fleeced the tops and the frost wiped them out completely, hubby is hoping they may do better in the open ground. no idea on his reasons but he is one of those people that doesnt try something that fails more than once
