Do you have a south facing sheltered area?
Simple answer - no. My holding faces east, the prevailing wind is from the SouthWest, although the North and East winds in spring are most likely to damage plants. However I do have some sheltered spots, but not particularly sunny. I have to generally choose one or the other and sunny sheltered spots are maybe reserved for more precious plants.
Thanks for the suggestion, I do rather favour edible (tasty) over structural. I note the description on Pfaf says the roots are quite shallow. Does that mean they might be suitable for growing on a leach field area? That is certainly as sheltered as anywhere. I'm thinking of planting more raspberries there at the moment. If they can be safely planted above drains, then our 'front garden' may also be a good spot. That is pretty sheltered and sunny. I've got an area of grass and nettles, since I'm expecting to dig it up from drains for our extension at some point in the next year or so
