Propagate by seed
From Late Winter TO Early Spring
Sow seed in late Winter or early Spring in good seed compost. Plant out, after hardening off, into well-draining soil
Propagating by division
From Mid Autumn TO Late Autumn
Established plants can be divided, and divisions replanted. A piece the size of a carrot will take root.
Flowering
From Late Summer TO Late Summer
White flowers that are attractive to bees appear in late Summer
Planting
From Late Spring TO Early Summer
Plant out seedlings when they are big enough to handle, and after hardening them off. Choose your growing site carefully, as you are likely to have horseradish for many years - they are a lot harder to get rid of, than to grow! They also spread. Choose a site that is free-draining and reasonably fertile, in full sun or partial shade..
