Does anyone have a recipe to make horseradish cream or sauce. I had a very easy recipe made with mayonnaise and have lost it.

Hi, I got my root stock from The Diggers Club. They carry all heritage seeds/roots/plants. I've been a member for years and have enjoyed great produce from their seeds.

Hello Roy, I live between Ballina & Lismore (NSW). Just dug up my horseradish (it's been in our subtropical garden for at least 18 months) and there's almost nothing but slender hairy roots! (But the leafy tops are magnificent!). Google indicates that we should be able to grow it well, but we haven't yet. Any tips, please? Same thing with celeriac. Have you ever tried that in Logan City. (Sometimes we get lost near you - whenever we come up to Ikea. Gonna try and get the correct exit no. showing prominantly). Thanks for your help. Bella

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.
