Celeriac – Giant Prague



Celeriac – Giant Prague is an excellent variety that produces large roots with an excellent flavour.


Celeriac isn’t the easiest vegetable to grow from seed.  In late March to mid April, sprinkle the small seeds thinly onto a filled 9cm pot containing fine seed compost and place on a propagator.  About 3 to 4 weeks afterwards prick out the seedlings into individual cells of a modular tray.  Plant out in mid-late May.
