The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Columbus you can figure out when to plant stocks by looking at the USDA zone info.

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 get them planted just a bit earlier than plants that are more sensitive to the cold.

The earliest that you can plant stocks in Columbus 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 really do well. Starting your stocks indoors is a great way to get them started a little bit earlier.
