Celeriac Overview

As a large globular, knobby and dull-coloured root that has a pronounced celery-like taste, the Giant of Prague is used and enjoyed throughout the culinary world for its great taste rather than for its looks. Celeriac is crisp, smooth, mild and has a delicious taste, a root of exquisite flavour and texture. Poorly known outside of Europe, this is a vegetable that is both tasteful and also has various health benefits, and is a great addition to any vegetable garden.

Common problems with Celeriac

Pests include leafhoppers, whiteflies, leafminers, carrot and celery flies, and Rhizoctonia solani.

How to harvest Celeriac

Celeriac is a slow growing vegetable that takes 5 - 6 months from sowing to harvest. Harvest small to medium sized celeriac roots for best flavour and texture. Begin as soon as the root ball reaches about 5cm. They will grow to about 10cm in diameter. Celeriac can be stored after harvest, but the best roots are from plants which have been freshly dug up. If your soil is free draining, leave them in the ground and harvest as required.

How to propagate Celeriac


Sow in Summer months. Celeriac is slow to germinate (2 to 3 weeks) and slow to get growing. Soaking seeds in water may aid germination.
