Typically, we plant potatoes in early February, but not his year. The soil is saturated and our seed remains safe in storage in Colorado. Sheldon would call me in late January and send a big semi with 22 pallets over the Rockies with potato seed for many of the organic farms in our area.  We are a drop off point for two other farms. 

The seed is grown at high altitude where aphids do not survive. As they are the vector for viruses of potatoes, we can be assured of fresh virus free seed each year.
