If your soil is volcanic they should do well the best horseradish I ever grew was in red volcanic soil in the Redlands east of Brisbane

Looking at growing horseradish on a sloping block in N.E. Victoria (Yea region). Does the plant need protection from kangaroos,rabbits and is it mainly disease resistant? Does it need much attention or can it be left alone?

I live in Vermont Melbourne 3133 and want to grow my own Horseradish.....Where can I buy a root locally ? I have had varying experiences with email purchases in the past so would prefer to drive and collect it. Thank You

Not exactly close to you, but Psarakos in Thornbury (fruit and veg grocery) seems to always stock fresh horseradish. It is up the back in a tub of water sold by weight. Today I just bought a lump with shoots coming out the top and planted it. Then I googled and found this page... Hopefully it will grow well.

As regards horseradish, I have grown this plant, but in my opinion, it would be a mistake to think you can plant it in April and harvest in 24 weeks time and have a useful root. For Horseradish to get a nice thick root, with the distinct pungent flavour, it takes a good two years per plant. And do not underestimate how much work it is to clean the dirt out before shredding the root. It is a wonderful taste and worth the hard work, but in my experience, you need to set up a dedicated bed, plant the roots and then prepare to wait a few years to get the cycle of having a constant supply of usable nice thick roots. The roots grow very deep into the soil (a good 2-3+ feet) so it is a good idea to leave some room around each group of plants, because you need to dig quite a wide hole to get the roots out. We always harvest at Easter here in Sydney. Bon apetit.
