It says plant Feb/Mar and you planted Dec. There could be your problem. Yours could be nearly ready to harvest but you still could be having frosts or snow. Not ideal. Take the advise here and plant later. Try your mulch and see how it works.

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.
