Start celeriac seeds indoors, in individual pots or cell trays, eight weeks before the last expected frost. (Like most root vegetables, it rarely appears as starter plants in nurseries.)

Choose a site that gets full sun. Celeriac likes soil that's moist, slightly acidic (pH 5.5 to 6.5), fertile and rich in organic matter. Amend the soil with plenty of compost or well-rotted manure the fall before you plant.

Transplant seedlings to the garden when temperatures rise above 50 degrees F, spacing the plants six to eight inches apart.

Add soil or mulch to keep the roots covered as they develop, but periodically pull this covering away and prune off the small feeder roots.

Begin harvesting as soon as the root ball reaches about two inches in diameter.

Tips:
Celeriac thrives in containers; a five-gallon pot will hold several plants.

A little cold weather will topple celery, but it will only improve the flavor of celeriac by spurring the conversion of its stored starches to sugar.

Broad bean's...if you mean Fava Bean's they are a cool weather crop. In the South they set them out in the winter for a sring crop. Here we planted our's when we planted the Pea's and they are HUGE Laura
