One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Vidor you can figure out when it's possible to plant alternaria by looking at the USDA zone info.

Planting Calendar for Alternaria

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

Alternaria do not do well in cold weather which tells us that you must wait until it warms up after the last frost before you can plant them.

The earliest that you can plant alternaria in Vidor 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 alternaria and expect a good harvest is probably September. If you wait any later than that and your alternaria may not have a chance to really do well. Starting your alternaria indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is February 15 in Vidor. In the coldest months of winter you should expect an average low temperature of 20°F.

Since the USDA zone info for Vidor is not always accurate the actual date of last frost can change quite a bit from year to year. Since half of the time in Vidor last frost occurs after February 15 be ready to protect your alternaria if you have one of those late frosts.
