The earliest that you can plant celery in Zone 1a is June. However, you really should wait until July if you don't want to take any chances.

The last month that you can plant celery and expect a good harvest is probably July. If you wait any later than that and your celery may not have a chance to fully mature. If you are starting your celery indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date
