2024 - the Garden Balance Sheet

Off on a bit of a tangent here but I've just read https://www.goodreads.com/book/show/1350...eed-supper. He's a new allotment owner and is convinced that it will pay for itself over a year. His son challenges him to prove this so the man "Martin" keeps a record of how much he has spent and the value of his crops. He values the crops at the price they would be in the local supermarket. His son agrees that he can write off the cost of tools and equipment over 10 years so if, for example he bought a GH costing £100, it would only cost £10 each year. They also agree that gifts don't count as expenditure - so he has gardening presents for his birthday.
At the end of the year he is £20 in profit but, most of that is made up by 3 things - redcurrants and raspberries, which were already on the plot when he took it over and lots of rhubarb which his plot neighbour gives him!
He concludes that if you want to make a profit, soft fruit is the way to do it.
