I planted horseradish 2 months ago in November Which month should I dig up Also do I just take a root segment and replant

It is in the notes here. Harvest time. Replant after winter I would assume.

Don't use a high Nitrogen fertiliser if you don't want a lot of leaves.

You just need ordinary soil. Keep it watered, a wooden box will dry out quickly. You cannot grow horseradish without leaves.

Work out your climate from the BLUE TAB Climate Zones at the top of the page. Go to the Horse Radish page, set the climate zone to your climate - TROPICAL. The recommended planting time is in the planting calendar.
