Main Crop Potatoes starting to flower

Help,

My main crop Potatoes which only went in the last week in March are full of lush green growth and are now starting to flower - surely this is far too early.  I have spent half the afternoon going around picking off the flower buds to try to put more growth back down into the tubers under the ground. 

Is there anything else I can do to help get better potatoes?

Just let nature take its course and let them get on with it. They know best.

Mine flowered some time ago and now have crab apple type thing on them - The earlirs are turning up their toes, I planted them on the 16th March and they were well chitted.
