Is it just me or has others noticed how pink fir apples (pfa) seem to work their way up nearer to top of soil as they grow ..Is this that they grow further up the haulms than normal spuds .. I noted last year that although I planted all my tatties same depth the pfa was still the shallowest when being dug up ..Reason I am posting this is as pfa's are in the soil quite a long time as in late season I have to keep earthing them up in order to avoid some green spuds and getting any frosted , As had happened the year before . Which made me take note as to the depth of planting etc...Has anyone else found the same?.cheers.. Jim
