The mesh was quite often of two or three sizes the first grid was a small mesh 1½" -2" square that let the small potoes through, these would be used as the following years seed! The next mesh was a bit bigger for 'eating' potatoes and those large ones that flowed off the end were 'bakers'
Using the previous years crop to re plant would be frowned upon these days. I often wonder how long ago was it that farmers started using specially purchased 'seed' potatoes?
Do you think it's really necessary for allotment growers to buy new seed potatoes every year?
How do the professional seed growers ensure they're free from disease? Do they test them in some way?
