In my first year I grew 97 bunches of grapes (OK the vine is established and has been going for around 10 years), 84 cucumbers, 1.4kg of rhubarb, 1360 good tomaotes, 4kg approx of green tomatoes and ones with bits cut out of them, 17.25kg runner beans, 8 small melons, 2L of goosgogs, 2 bunches of carrots and 2 very pathetic and shriveled aubergines. The biggest saving I made in comparison to the rest of you was in not forking out for an allotment! I did this in 2 borders of a 4x3 m garden, the 2 window sills of a conservatory the same size, a fairly large quantity of upcycled big plastic paint pots scattered around the former 2 areas, 4 window sills in the house and 5 pots by the path in the front garden!
Nothing has been wasted or given away, it' s all either been eaten or is in the freezer. After reading the entire thread in detail I've concluded that an allotment is everything that the responders who've never bothered about the cost say it is, but as a purely financial proposition it's nowhere near as cost effective as growing somewhere else that doesn't cost £55pa rental! So for year 2 I'm modifying what I grow and where I grow it and won't be expanding into an allotment!
