If you're not the type of person that wants to spend their time managing an elaborate fruit or vegetable garden, you might consider planting and maintaining an herb garden. While the product might not seem as significant, you'll still enjoy the constant availability of fresh, delicious herbs to flavor your meals with.
First you'll want to choose the herbs that you'll plant. You might have a hard time doing this because of the huge scope of herbs available. But the best way to choose is to do what I did; just look at what you have in your kitchen. By planting your own collection of these herbs, you can save money on buying them from the grocery store while having the added benefit of freshness. Some of the herbs you might start with include rosemary, sage, basil, dill, mint, chives, and parsley among others.
