One way of making a decision about when it's a good idea to plant celery is to consult the USDA zone info for Sidney.

Planting Calendar for Celery

Frost tolerance for celery:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Celery can survive in very little cold which means that you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant celery in Sidney 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 celery and expect a good harvest is probably August. If you wait any later than that and your celery may not have a chance to really do well. If you are starting your celery indoors then you might be able to get away with starting them a couple of weeks earlier.
