Whatever that actually is! I keep my nails short (for gardening in the summer and bowling in the winter -- sorry, winter is long up here!), and my nail brush is my best friend. Just can't wear gloves for most gardening things, but serious raking, hoeing, etc. is a lot more comfy with an extra layer of hide on your hands. I have friends that "hate dirt," but really -- don't you have to like dirt if you garden??
