One of the first jobs of the veg gardening year is to start to force and chit some potatoes. Chitting means sprouting the tuber – putting it, most eyes upright, in a light, cool but frost-free place at about 50F (10C). I put half mine in the porch by the window and half in the greenhouse.
Just so, how can I quickly chit potatoes?
Chitting potatoes forces them to sprout a few weeks before you plant them. This speeds up the growing process and gives you a bigger harvest. Use seed potatoes and let them sit in a cool, light place for several weeks. Once they've sprouted, you can plant them in warm soil.
when should you start chitting potatoes?
Chitting simply means encouraging the seed potatoes to sprout before planting. Start chitting from late January in warmer parts of the country or in February in cooler areas, about six weeks before you intend to plant out the potatoes.
There is no real advantage to growing potatoes from store bought ones (those soft, sprouting grocery store potatoes will make good compost). However, if you feel the urge to grow those sprouting potatoes from the supermarket, plant certified seed potatoes too.
