The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Audubon you can determine when it's possible to plant scallions by checking out the USDA zone info.

Planting Calendar for Scallions

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

Scallions tend to make it in very little cold which means that you can plant them a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant scallions in Audubon 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 scallions and expect a good harvest is probably August. You probably don't want to wait any later than that or else your scallions may not have a chance to fully mature. Starting your scallions indoors is a great way to get them started a little bit earlier.

Last Frost Date

Since the USDA zone info for Audubon is not always accurate the actual date of last frost changes from year to year. Half of the time in Audubon last frost occurs after April 15 so make sure that you are prepared to protect your scallions if you have a surprise late frost.
