Although I have removed any horseradish or mares' tail along the way there are a lot of grass roots and such like in the allotment compost heap. I'm hopinge the little slithery tikes will help break them down over the winter.
Meantime here's the state of play from a rotational point of view. I now operate a five year rotation of Potatoes/Beans/Brassicas/Alliums/Other Roots.
Next year's bean patch - currently leeks for the winter:
And in between them next years Brassica patch. (Currently lettuce rocket radishes watercress and lambs lettuce - and in need of a weed)
Next year's potato patch. There are still parsnips and spinach beet growing here alongside the perenial globe artechoke. beyond that all the carrots have gone.
Last of all, this year's brassica patch is to be next year's Other Roots (other than potatoes)
