When should I harvest my horseradish ? Very leafy i its own raised bed and looking real healthy

Horseradish would normally be harvested in the winter when it is dormant but there is no reason why you couldn't dig down beside the plant and raid a few root pieces. the plant is almost indestructable and any small pieces of root left in the ground will grow. keep the manure, water and mulch up for good quality roots. trust this helps.

Hi I'm staying in Pretoria CBD.I really need the horseradish roots where can I get it?

I would try Permaculture and gardening groups. You only need a small piece of root to get started and then you will have it for life! Food Growing plant nurseries could also have it. Trust this helps.

Yes very frustrating not to be able to buy a Horse radish plant in South East Queensland,, The shop bought horse radish cream , is very poor quality,

Horse radish will be in leaf by now. You should be able to get it from places like Green Harvest' online. I am happy to send you a few pieces of root from my plants if you can't find it. Reply to this email if you want some. It is very easy to grow from pieces of root. just plant them with the thickest end level with the soil and they will soon sprout. Trust this helps.

Hi John, We have been looking for horseradish for months and can only find it on ebay. Not to keen on buying plants online. If you still have some to spare I would be more than happy to pay for postage. Thanks Dave
