The earliest that you can plant stocks in Oregon is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant stocks and expect a good harvest is probably August. Any later than that and your stocks may not have a chance to fully mature. You can get started a few weeks earlier by starting your stocks indoors.
