Alys Fowler: horseradish
Horseradish (Armoracia rusticana) is easy to grow – perhaps too easy, as anyone who's left it unharvested will find out. It's a clump-forming perennial that becomes invasive if not regularly harvested. It will grow anywhere damp and doesn't mind partial shade, but for fat, straight roots, you need good fertile soil rich in well-rotted organic matter. Old, neglected plants tend to have woody roots that aren't much use in the kitchen, so split clumps every three years. This can be done now
