One of the first steps you take when you are determining your gardening schedule is find your USDA Zone info. 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 a good idea to plant celery is to look at the USDA zone info for Graham.

The last month that you can plant celery and expect a good harvest is probably August. Any later than that and your celery may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your celery indoors.
