The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of estimating when it's the best time to plant green beans is to refer to the USDA zone info for Harvey.

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

The earliest that you can plant green beans in Harvey 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 green beans and expect a good harvest is probably August. Any later than that and your green beans may not have a chance to fully mature. If you are starting your green beans indoors then you might be able to get away with starting them a little bit earlier.
