My husband and I recently moved to a charming old farmhouse apartment and have been contemplating where our new garden will be and what we will grow in it. When searching for useful gardening websites, I ran across the National Gardening Association website, www.garden.org . I am a fairly new gardener and need a little hand-holding from experts so I found this website especially useful because of its wide range of information including how-to videos and pest control information.
You might be interested, as I was, in the Plant Finder. You can select your criteria for a plant (zone, color, soil type, lighting and more) and the website will generate a list of plants that fit your description.
Happy gardening!
