Growing your own food can save money, but a garden does not automatically turn a grocery bill into pocket change. Seeds cost money, soil amendments cost money, containers cost money, and that adorable little tomato plant at the garden center somehow knows exactly how to make a gardener spend more money. A garden can absolutely produce inexpensive food. But the savings usually appear when gardeners choose crops carefully, and use what they already have.
That distinction matters because gardening often gets treated like a guaranteed money-saving hobby. It is not. A backyard filled with expensive raised beds, specialty soil, elaborate irrigation equipment, and dozens of ornamental vegetable varieties can cost considerably more than simply buying produce.
