The earliest that you can plant stocks in Parker 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. You probably don't want to wait any later than that or else your stocks may not have a chance to grow to maturity. You can get started a couple of weeks earlier by starting your stocks indoors.
