It is no secret that when I have a gardening question, a Google search is usually my first (and often, last) resource. But I have recently discovered a gardening website that provides even better, more focused, expert information: Gardening Know How. You can search virtually any gardening question there, as well as see popular questions asked by other gardeners. And if you don't find what you are looking for, you can can submit your own question to be answered. And there are pictures! I highly recommend it.
