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 Lebanon you can estimate when you can plant alternaria by using the USDA zone info.

Planting Calendar for Alternaria

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

Since alternaria are not cold tolerant it is necessary to wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant alternaria in Lebanon 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 really do well. If you are starting your alternaria 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 Lebanon. It might get as low as -5°F during the coldest months of winter.

Always keep in mind that USDA zone info for Lebanon is just an average and the actual date of last frost is different every year. Half of the time in Lebanon you get a frost after April 15 so be sure to be ready to cover your alternaria in the event of a late frost.
