Alfalfa makes good forage crop for the late spring/mid summer months. The deer like to bed in the grass/alfalfa mixture that I have. In our area it's pretty robust, growing in anything from loam to clay, as long as the drainage and pH are reasonable.

I'd recommend that you plant clover as your main forage crop and use the alfalfa as a side crop. Greg-Dude is correct about the mowing.
