potato dig

i harvested the rest of the north side of the back potato bed to start the green manure project ( the other half is there if anyone wants to dig them )...the farther east i went in the bed the better the yield and i am assuming it is because that side of the bed got more sun...the pound of spuds to a plant rule seems to be holding for this bed...please fell free to harvest them but try not to disturb the half of the bed i just planted...i would really appreciate that.
