Horseradish will grow in full sun or part shade. It is a very hrdy plant and will spread rapidly in good conditions. To contain it you can plant it in a large planter pot and sink the pot into the ground. Horseradish loves damp conditions and in this situation will produce the best roots but will still do well with less water. Trust this helps

Horse radish would normally be harvested when it is dormant but there's no reason why you couldn't dig down beside the plant an bandicoot a few roots for your favourite source! Horseradish is very hardy and any piece left in the ground will grow. Trust this helps.

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 Jackie, I know it was a long time ago, but do you still have any horseradish in Launceston ? I am in Beaconsfield and would love to grow some so I can make Fire Water with it. Donna.
