Celery and Celeriac!
Celery and celeriac have a very long growing period. Seeds should be started 14-16 weeks before temperatures stay above 50F. Celery and celeriac are temperature sensitive!
I soak my seeds overnight prior to starting- I am careful to label them as these two twins are identical.
We start our celery and celeriac in 2″-4″ pots. Although they take months to grow to a transplantable size, I have found that minimizing rehoming is what celery and celeriac prefer.
Sow seeds 1/8″-1/4″ deep setting the containers on a heat mat set at 75F. We use a dome cover or plastic wrap to ensure consistent moisture during this critical germination period.
We keep these beauties under lights, provide air movement and we feed them every 3 weeks or so.
I will be keeping my eye on the calendar come May for consistent temperatures above 50F.
