How to Plant Potato Tubers in Oregon
Although you can grow potatoes in most areas of Oregon, central and eastern Oregon are ideal potato-growing regions for their short growing seasons and cool evening temperatures. Wait until after the last frost date in your area and for the soil to warm to at least 45 degrees Fahrenheit to plant. Then, choose a location in which potatoes or tomatoes were not grown the previous year. This will help reduce the chances of verticillium wilt and other diseases. Does this Spark an idea?

Amend the planting bed with 4 inches of coarse sand, mixed to a depth of 8 inches. Agriculturists with Oregon State University suggest that new potato crops require a soil analysis, which is available from your county cooperative extension office. If you do not obtain a soil test, they suggest that 23 lbs. of 10-10-10 fertilizer per 1,000 square feet of planting area, mixed to a depth of 8 inches, is sufficient for most Oregon gardens.
