Might be a chance to grow those fruits that are sought but not worth garden space. Crabapple, quince,medlars, figs, apricots if climatically suitable .Horseradish, wild garlic, anything insect friendly. Would like to see photos if possible. Keep up the good work, the old railway porters (who remembers those?) were renown as having good gardens, with plenty of 'free time' between trains.
