Growing rhubarb (& possibly veg or herbs) under Apple trees
I'm busy turning my gardening into an edible garden, including planting a few 2yr-old fruit trees (apple, cherry & plum) along a south facing fence. My mum says that in 1960s the nearby orchards grew rhubarb under apple trees. Can anyone give me some advice please about whether this is a good idea to do in my garden?...it has plenty of well-rotted manure dug in to it. And if not, what else will be good companion plants to grow under the fruit trees?
My garden is long & thin (a ratio of 1:7.5) and is mostly sunny (apart from a 3 feet strip of deep shade running along north facing long fence line & the area under my neighbour's enormous 40 foot Christmas tree where not even grass grows!). So I need to make the most of the remaining 9'x50' south facing strip.
Thanks for your help
