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.
