One of the first steps you take when you are estimating 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.

The USDA zone info for Zone 9a should be reviewed to estimate when to plant snap beans.

Planting Calendar for Snap beans

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

You really shouldn't plant snap beans until after all chance of frost has passed because they are not cold tolerant.

The earliest that you can plant snap 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 snap beans and expect a good harvest is probably September. If you wait any later than that and your snap beans may not have a chance to really do well. If you are starting your snap beans indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on February 15 in Zone 9a. You should expect an average low temperature of 20°F in the coldest months of winter.

Since the USDA zone info for Zone 9a is not always accurate the actual date of last frost will vary from year to year. Since half of the time in Zone 9a last frost occurs after February 15 be ready to protect your snap beans if you have a late frost.
