One of the first steps you take when you are figuring out 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 Zone 9a you can estimate when it's possible to plant green beans by referring to the USDA zone info.

Planting Calendar for Green beans

Frost tolerance for green beans:	Not tolerant of frost.
When to plant:	After the last frost has passed.

It's probably not a good idea to plant green beans until after the last frost has passed because they are not cold tolerant.

The earliest that you can plant green beans in Zone 9a 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 green beans and expect a good harvest is probably September. If you wait any later than that and your green beans may not have a chance to grow to maturity. Starting your green beans indoors is a great way to get them started a little bit earlier.

Since the USDA zone info for Zone 9a is just an average the actual date of last frost will vary from year to year. Since half of the time in Zone 9a you get a frost after February 15 be ready to cover your green beans if you have a surprise late frost.
