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)

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.

Margaret, I haven't found the perfect time, the size of the leaves don't tell me anything. Last week I did use some, just scraping away surrounding soil and seeing the thickness of the root helped, the root was fairly thick, about the same as two fingers plus a little more. Getting it out is the hard part, the roots go down a long way so I cut the amount I needed and replaced the soil. Be careful if you do this because the root is very strong, a serrated knife worked o.k
