One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A common way of determining when it's possible to plant stocks is to consult the USDA zone info for Hopkins.

Planting Calendar for Stocks

Frost tolerance for stocks:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Stocks are barely cold tolerant which tells us that you can start planting them slightly earlier than other frost tender plants.

The earliest that you can plant stocks in Hopkins 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 fully mature. If you are starting your stocks indoors then you might be able to get away with starting them a couple of weeks earlier.
