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

A common way of getting a good idea when to plant alternaria is to consult the USDA zone info for Gallup.

Planting Calendar for Alternaria

Frost tolerance for alternaria:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

Since alternaria require warm weather you really should wait until after the last frost has passed before you can plant them.

The earliest that you can plant alternaria in Gallup is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant alternaria and expect a good harvest is probably August. You probably don't want to wait any later than that or else your alternaria may not have a chance to fully mature. Starting your alternaria indoors is a great way to get them started a few weeks earlier.

Last Frost Date

In Gallup the average date of last frost happens on April 15. You should expect an average low temperature of -10°F in the coldest months of winter.

Since the USDA zone info for Gallup is not always accurate the actual date of last frost is different every year. Since half of the time in Gallup there is a last frost after April 15 be ready to cover your alternaria in the event of a late frost.
