The world of domesticated potato growing is a venerable one, going back some 9000 years to the shores of Lake Titicaca on the border of Peru and Bolivia. This ‘super food’ (it has pretty much got every nutrient you need keep healthy) has since become the fourth most important food crop in the world. The biggest cultivator of potato is China.
However with over 5000 varieties of potato worldwide, the potatoes grown in China or Africa or in South America are probably different from those we favour in Ireland. Our favourite spud bought by almost half of Irish consumers is the Rooster, which was bred here expressly to suit the Irish palate.
Early varieties (such as Colleen or Orla) get sown first, followed by ‘second earlies (such as Carlingford) a few weeks later. The main crop (such as Rooster) is planted later in Spring to mature later giving a bigger yield and some is stored until the ‘earlies’ are harvested the next year.
Before planting my few Orla seed potatoes in grow bags at the end of February, I first show them light in a frost free environment for a couple of week so that they sprout. This can speed them on their way once they are planted in a soil and compost mixture.
Chitting is the word used to sprout seed potatoes before planting. It is a simple procedure as the following video shows. The only precaution worth noting is be sure your seed potatoes are disease free. I make sure I buy mine as ‘certified seed potato’, for peace of mind.
