In the past I always bought my potatoes from the Allotment Association but I seemed to get too many that did not grow or just died off despite loads of farmyard manure and potato fertiliser. Last year I saved some of my own seeds and used a local garden centre for the rest. Result best year that I have ever had I still have 4 bags in the garage. I have saved more of my own this year especially Manitou which I cannot get any where and which my wife thinks are the best late cooking potato. I will set 3 rows of Lady Christi earlies one row of Maxine, two rows of Harmony and two rows of Manitou and the lot will have cost me £18 which is far cheaper than buying all new stock each year and I can choose my own seed. The few that I have bought I have had to dispose of some of the seed potatoes because of faults.
