(Best months for planting Horseradish in Australia - temperate regions)

P = Plant direct in garden where they are to grow.


  • Easy to grow. Plant root pieces. Best planted at soil temperatures between 10°C and 25°C. (Show °F/in)
  • Space plants: 50 cm apart
  • Harvest in 16-24 weeks. Some improvement in flavour if left till after frost..
  • Compatible with (can grow in same bed): Best kept separate
  • Horseradish leaf

Horseradish is grown from root cuttings. If you know someone who has it in their garden, just one piece of root will start off for you.

Dig a deep hole and refill with compost as the horseradish has a long taproot. Plant it and then leave it alone. Apart from constant wet or cold, horseradish will grow in any part of the garden.

Horseradish is an aggressive grower and will quickly take over the garden. It will also grow well in a deep container or sink an old bucket in the ground to prevent spreading. Otherwise, remove all the plant when you harvest it and save one piece to replant.

Can be planted in early Autumn or Spring

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.
