One of the first steps you take when you are determining your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Audubon you can estimate when to plant asparagus by checking out the USDA zone info.

Planting Calendar for Asparagus

Frost tolerance for asparagus:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Asparagus do ok in cold weather which tells us that you can plant them much earlier in the year than more sensitive plants.

The earliest that you can plant asparagus in Audubon is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant asparagus and expect a good harvest is probably September. If you wait any later than that and your asparagus may not have a chance to really do well. If you are starting your asparagus 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 Audubon. You should expect an average low temperature of 0°F in the coldest months of winter.

Just be sure to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Audubon and it changes from year to year. Half of the time in Audubon there is a last frost after April 15 so always be ready to protect your asparagus in the event of one of those late frosts.
