Here in Michigan, many vegetable gardeners are beginning to harvest their first tomatoes of the season. Most will agree that nothing tastes quite like a tomato grown in your own garden. In particular, people have commented for years about the taste, or lack thereof, in tomatoes purchased from the grocery store. Why is that?
