The goal of your organic garden should be to put out as much produce while using as little outside resources as possible. According to organic principles, this means that you should not buy any nutrients, fertilizers, or pesticides from the store. It’s even better to avoid using water from your hose, and instead gather rain water. Instead, you should try to use your resources as best you can to create a healthy crop. It’s a bigger challenge, but it’s worth it in the end.
Instead of throwing away vegetables and other food waste, you should start a compost heap. This is, by far, the best way to manufacture your own nutrients for your garden. You will find that there is no shortage of material to add to your compost heap. When you mow the lawn, put all of the clipped grass into the heap. Put all of your food waste into the pile. Once it’s hot and ready, you can spread it on your garden and watch the plants flourish.
