Celeriac can be started indoors, which is good since it tends to grow so slowly initially. The seedlings like a fairly cool 60˚ F for growth. Take care to keep them moist. It is likely they will take 8 to 12 weeks to reach the desired size for transplanting. Make sure to harden off the seedlings before transplanting them outdoors.
