So this is one isn't about saving money because you are growing your veggies and maybe some fruits. Gardening is a good form of exercising. It is a proven fact that someone can get as much exercise as someone working out in a gym. Yeah, there is a difference but unless you are an aspiring body-builder, you'll get enough exercise to stay fit and healthy.So when gardening, think of it as killing two birds with one stone. You'll be saving money growing your own vegetables and at the same time, you don't have to pay any gym fees.
