. Best of all, send for a test kit and have your soil evaluated! I've got clay soil. It needs things to break up the clay, like sand.
I am not sure that adding sand is always the way to go. Organic matter, either already broken down, or at least party so, may be more suitable, though I am hardly an expert.
If you wish to be patient, you could just plant a thick crop of, say, long radishes in your patch, let them mature, then rot, then rototill or dig the whole mess in. You will end up with lovely, well-draining soil.
