Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Posen you can estimate when to plant shallots by using the USDA zone info.

Planting Calendar for Shallots

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

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

The earliest that you can plant shallots in Posen 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 shallots and expect a good harvest is probably August. You probably don't want to wait any later than that or else your shallots may not have a chance to really do well. Starting your shallots indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is April 15 in Posen. In the coldest months of winter you should expect an average low temperature of -10°F.

Since the USDA zone info for Posen is not always accurate the actual date of last frost will vary from year to year. Half of the time in Posen you get a frost after April 15 so just be sure to be ready to cover your shallots if you have one of those late frosts.
