Can horseradish be grown in a pot? If so what size/ depth do you suggest ? I have a couple of old kiddy pools and was wondering if they would be too shallow? I am in sub tropical area and very new to gardening. Cheers Cate

I planted a horseradish plant early June just as an experiment. It is growing more leaves (in a pot) and seems to be in really good shape... So when do I harvest it, since I have planted out of the recommended planting period? (In Sydney near the coast)

Thank you every body for your reply to my request for buying Horseradish, I ask at my local Food Works store and bingo I got a large bag full in five days.

I have just bought a bag of Horseradish plants and I'm going to make a sauce, then put it into jars. With the tops can I plant these in my garden now or put into boxes in compost. I live Bacchus Marsh Vic.

I do not like horseradish, but I am a seed and plant maniac.Yesterday (Sunday 18th May 2014) I found dryish pieces -roots- at our local PnP in Lambton, Germiston. I will re-hydrate them to hopefully revive them and see if they will grow. Will keep you posted.
