I recently tried growing potatoes using a method I saw on TV. This is just cutting up potatoes into reasonable sized sections and placing them several inches down. The results have been fantastic.
While doing some research on how to grow potatoes I have read that I should be using seed potatoes, not cuttings from store bought potatoes. The main reason given is disease.
How high is the risk in using cuttings from store bought potatoes? Are there any other reasons that I should use expensive seed potatoes (considering a bag of potatoes is inexpensive and one potato cut up can produce 4 plants)?
Even Yates suggests that it is not entirely necessary:
It’s best to buy the certified disease-free seed potatoes that are available at this time of year, but you can choose healthy potatoes from your vegie drawer
