Anyone with an allotment?

get yourself down morrisons
buy a 5kg bag of maris piper
get the 5 biggest spuds and just plonk them in the ground
they'll take care of the seeding themselves
i chucked some out on the compost heap a month or so back and they are already in full leaf and growing
alternatively your local garden centre

Not experienced with growing foods =)
Got any tips on what you need to do to help the fellas grow?
And how much growing space do you need to give each spud?

Got a lot of unused garden space and would love to grow my own veg.
