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.

One way of making a decision about when to plant alternaria is to consult the USDA zone info for Monroe.

Planting Calendar for Alternaria

Frost tolerance for alternaria:	Not tolerant of frost.
When to plant:	After the last frost.

It's probably a bad idea to plant alternaria until after the last frost when the weather gets warmer because they do not do well in cold weather.

The earliest that you can plant alternaria in Monroe 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. Any later than that and your alternaria may not have a chance to fully mature. You can get started a few weeks earlier by starting your alternaria indoors.
