  • 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

How can I determine when horseradish rhizomes are ready to harvest. Time is a bit out of whack because it took ages for it to take. Currently the outer leaves are about 45cm long 15 cm wide clear healthy emerald green colour with many smaller leaves inside them. I planted a single piece of 5 cm rhizome in a 30 ltr veg bag in March this year. Only started going about a month ago but is going very well now.
