It's interesting to think that a lot of the we get at the grocery store sometimes has to travel across states to get to where we live--even produce that can just as easily be grown in your back yard.
Although not not all of the ingredients in my salad I ate with dinner last night came from my garden, some of it did. It was fun to be able walk two feet from my back door and pick fresh loose leaf lettuce, basil and chives to add to the mix. If I had grown carrots, I would have added them instead of the ones I got from the store. Maybe someday.
The lettuce and basil came from seed, and the chives were from a start I planted last year.
I encourage you to plant produce close you, either from starts or seeds. It's quite fun and satisfying when it comes time to cook, especially when you plant something that is cheap to grow but expensive to buy at the store, like herbs.
