I am new to Boise and will be moving into a new home which already has a few raised beds in it! Great, but these beds have been sitting fallow with no amendments for I don't know how long.

I want to plant a fall crop, Brassicas and the like, beans, peas, amending the soil first with compost. After this, I'd like to plant cover crops to add nutrients and prevent soil/water erosion over the wintertime. Any suggestions for cover crops? Perennial vs. annual? Winterkill vs. not?

thanks for the help!
