Bought my first seed spuds yesterday, 10 x Picasso from Wilkos, £1.50 for a small bag full  that weighed just under 1Kg. I've also ordered 2.5Kg of Kondor seed spuds (these are normally difficult to buy locally as not many outlets sell them). Don't normally buy them this early (would ideally get them when reduced towards end of planting season) but these are the 2 varieties I grow for the 'heaviest potatoes' show class which have all but one shoot removed prior to planting and allowing time to heal, then they're brought on in trays (so any further shoots can be removed) then transplanted to pots before planting in open ground in raised beds under cloches. Unfortunately I had severe problems with scab last year which prevented my best spuds breaking the 3lbs barrier. They would have grown much heavier, but stalled at less than 3lbs each and then proceeded to rot.  Wilkos loose seed spuds have dramatically increased in price, 10 medium/large'ish size spuds for 0.95Kg. That's about twice the price they were last year!
