Best way to store Charlotte potatoes for August planting

Like a lot of people I've never had any success with Christmas potatoes so I don't bother. In theory if you keep the tubers cool (think salad drawer of the fridge) they should refrain from sprouting but this didn't work for me either. Then you have to think about giving the plants some protection as any frost will kill them.

Personally I'd stick with the traditional roasties at Christmas.

I just cut hallam down when potatoes are ready and cover them with extra soil initially, then when likelyhood of frost I cover them with old carpet or straw etc and leave in situ until required.    When Christmas eve comes I uncover potatoes and dig up, always delicious results, as the taste of new potatoes at Christmas is to die for.  Never has this failed me, therefore I do not bother in August.  Bay Laurel
