With
all of this rain (another inch and a half yesterday), I have to keep an
eye on the potatoes. Dirt tends to wash away from the highest
tubers, leaving bare tops which turn green in the sun. So I've
changed my mulch priorities from tomatoes to potatoes and am slowly
covering up the rows of tubers with grass clippings.
I've always been intrigued by the history of our crop plants, and
potatoes have some of the best stories. They've been cultivated
in the Andes in South America for about 7,000 years, but didn't leave
the continent until Spanish explorers brought the plants back to Europe
in the sixteenth century. Even then, the potato had a very
limited appeal --- it was considered fit only for the lower classes and
was mostly used to feed hospital patients.
Two hundred years later, the potato wandered up to Ireland, where it
was welcomed with open arms. The Irish discovered that an acre of
potatoes could feed 10 people, and the population of Irish people and
potatoes quickly exploded...only to crash together sixty years later
when the potato famine proved the dangers of monoculture. If you
haven't heard enough, check out this
page which has even more fun stories about potato history.
