Are you sure the spuds are under the banked up bits?We dig a trench (10" deep)- fill with all the usual stuff and cover to the required depth (5"), therefore this is lower than the surrounding ground. when the shoots come up we just pull earth in from the sides until level.I realise i havent explained this too well!
Those who plant deeper may have taken their lead from the commercial growers who plant at 8". Why the difference?
