Washington and Oregon potato growers have been slowed slightly by a wet winter and spring. But so far, the crops appear to be worth the wait. Washington growers planted 170,000 acres of potatoes in 2016 and acreage and volumes are expected to be similar in 2017. “Last year was crazy early, as the weather promoted early season growth,” said Chris Voigt, executive director for the Washington State Potato Commission, Moses Lake.
