How much income/profit can I make a month/year by growing and selling edible crops on a small lawn?

Question

The Garden size is 10X10 feet.

Answer 1

unfortunately, with a garden that size I don't really see any way to make any money. You would need a space at least 100x100 to make it worth your time and effort. Even at that the best money making crop to grow is herbs for the size area--because they can be sold dried (cheap dehydrator) or fresh. That way you don't have to worry about spoilage.
