When to plant:	Up to 3 weeks before last frost.

Since celery are barely cold tolerant you can plant them slightly earlier in the year than more sensitive plants.

The earliest that you can plant celery in Aberdeen is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant celery and expect a good harvest is probably September. You probably don't want to wait any later than that or else your celery may not have a chance to fully mature. Starting your celery indoors is a great way to get them started a little bit earlier.
