I met with our new gardener when we were down over easter and have found out we have a lot of things that we didn't know we had. We have now identified the following edible things in our garden (if I remember correctly).
15 Walnut trees
2 sweet chestnut trees
1 lime tree
2 fig trees
1 peach tree
15 grape vines
1 cherry tree
2 plum trees
1 hazelnut tree
lots of mint and rosemary

We have to cut down 6 trees as they have had a good life and it is time for them to go...
