I don’t recall having tried growing swedes (Brassica napus) before but I was at the allotment today planting out some young plants we started a few weeks ago into a patch I recently cleared some broad beans from. Apparently they are quite closely related to Oilseed Rape and produced from crossbreeding cabbages with turnips.
The challenge now is to continue to water regularly. They are in a sunny position in fertile soil, which they should like, but it will have a tendency to dry out fairly quickly, particularly in the kind of weather we are having at the moment.
