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.

I bought the Horseradish cuttings from eBay. They were sent from Springvale in Melbourne. Fast and easy and they all took off

I've read conflicting answers as to growing horseradish in zone 10a. It's true that Florida has awful soil, especially close to the west coast. I love horseradish and it's hard to find the real pungent horseradish in the stores. Can i place a 5 gallon bucket in the ground and fill it with good soil and plant the horseradish in like November and let it grow till the end of February, after our frost warnings before harvesting? Winters here are fairly dry, so root rot shouldn't be a problem, and the months of December through the beginning of February are cooler with temps staying primarily in the 50°-60° range during the days and 40°'s overnight. Some frost may occasionally occur.
