One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The USDA zone info for Wyoming should be read to figure out when to plant stocks.

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.

Since stocks are barely cold tolerant you can plant them just a tiny bit earlier in the year than more sensitive plants.

The earliest that you can plant stocks in Wyoming 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. If you wait any later than that and 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 little bit earlier.

Last Frost Date

The average date of last frost is April 15 in Wyoming. You should expect an average low temperature of -15°F in the coldest months of winter.

Since the USDA zone info for Wyoming is just an average the actual date of last frost will vary from year to year. Half of the time in Wyoming you get a frost after April 15 so always be ready to protect your stocks if you have a late frost.
