I've come to this thread rather late in the day and haven't read all the way through it yet. Meanwhile here's a poem by one of my favourites, Seamus Heaney. I got modded for posting this on a BBC board!

My spuds got quite badly scorched by the frost which we had at the bank holiday weekend, especially a row of Charlottes but my neighbours at the allotments seemed to escape completely

That's often the way with late spring ground frosts, they are very patchy.
At A Potato Digging
I
A mechanical digger wrecks the drill,
Spins up a dark shower of roots and mould.
Labourers swarm in behind, stoop to fill
Wicker creels. Fingers go dead in the cold.
Like crows attacking crow-black fields, they stretch
A higgledy line from hedge to headland;
Some pairs keep breaking ragged ranks to fetch
A full creel to the pit and straighten, stand
Tall for a moment but soon stumble back
To fish a new load from the crumbled surf.
Heads bow, trucks bend, hands fumble towards the black
Mother. Processional stooping through the turf
Turns work to ritual. Centuries
Of fear and homage to the famine god
Toughen the muscles behind their humbled knees,
Make a seasonal altar of the sod.
II
Flint-white, purple. They lie scattered
Like inflated pebbles. Native
to the blank hutch of clay
where the halved seed shot and clotted
these knobbed and slit-eyed tubers seem
the petrified hearts of drills. Split
by the spade, they show white as cream.
Good smells exude from crumbled earth.
The rough bark of humus erupts
knots of potatoes (a clean birth)
whose solid feel, whose wet inside
promises taste of ground and root.
To be piled in pits; live skulls, blind-eyed.
III
Live skulls, blind-eyed, balanced on
wild higgledy skeletons
scoured the land in 'forty-five,'
wolfed the blighted root and died.
The new potato, sound as stone,
putrified when it had lain
three days in the long clay pit.
Millions rotted along with it.
Mouths tightened in, eyes died hard,
faces chilled to a plucked bird.
In a million wicker huts
beaks of famine snipped at guts.
A people hungering from birth,
grubbing, like plants, in the bitch earth,
were grafted with a great sorrow.
Hope rotted like a marrow.
Stinking potatoes fouled the land,
pits turned pus in filthy mounds:
and where potato diggers are
you still smell the running sore.
IV
Under a white flotilla of gulls
The rhythm deadens, the workers stop.
White bread and tea in bright canfuls
Are served for lunch. Dead-beat, they flop
Down in the ditch and take their fill,
Thankfully breaking timeless fasts;
Then, stretched on the faithless ground, spill
Libations of cold tea, scatter crusts.
