About Celeriac

Celeriac (celery root) is a rewarding but demanding crop with a long growing season. The knobbly root has a mild celery-like flavor and stores well all winter.

Start indoors 10-12 weeks before last frost — one of the earliest indoor starts of the season. Transplant after all frost risk. Keep consistently moist. Trim side roots as bulb develops. Harvest before hard freeze.
