Celeriac - Giant Prague The roots of this variety are globular with a slightly flattened base. It has medium green foliage. This type has a good flavour and stores well. It is easy to grow as long as the seeds are sown early and kept constantly moist throughout its life, in order to get good sized roots. Sow under glass at 16C in February or March in seed trays or modules (can be sown in a cold frame in March and April but it will not get so large). Prick off into individual pots or thin modules to single seedlings. Gradually harden off before planting out in May, in rows 30-35cm apart each way. Remove some of the outer leaves in July to expose the crown. Harvest from late September onwards.
