When to plant:	Up to 3 weeks before last frost.

Stocks are one of those plants that can tolerate a tiny bit of cold weather which tells us that you can plant them slightly earlier than more sensitive plants.

The earliest that you can plant stocks in Vail is April. However, you really should wait until May 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 really do well. If you are starting your stocks indoors then you might be able to get away with starting them a couple of weeks earlier.
