Good afternoon Charles,
I have bought our seed potatoes this year from a Scottish supplier (http://www.jbaseedpotatoes.co.uk/) and they cost me much cheaper than last year and so far among all the 2.5 kg bags I have opened I have only seen one potato with small cut. Last year when I bought from another supplier in the south England they had lots of cut and mouldy potatoes.
I choose my potatoes by looking up for each variety in the Potato Book by Alan Roman (Frances Lincoln Limited Publishers. I bought it from Foyles bookshop in London) which contains the most descriptive and illustrated list of all potato varieties available in the UK.
I noticed that JBA SEED had all of them in their comprehensive web site, plus many sundries (hessiyan sacks, planter bags, chicken manure fertilizer and even onions and shallots and garlic!).
They also sell 25 kg bags for those who want to grow more.
I thought others in the forum may like to know about this since I noticed many only know very mundane and ordinary places with limited variety. I like to call JBA Seeds of Scotland as Potato Haven!
Kind regards
Desiree, Sarpo Mira, Picasso have all grown rapidly and vigorously. The small-scale purchases of Arran Pilot, Red Duke of York, Pentland Javelin and Cara have also done well.
Obviously the final test is in terms of yield and taste, but to date, everything is going very well.
