We plant iron clay peas in spring, sometimes along with milo. They did really well until last years severe drought when the peas died out on two properties. The other place got a rain or two at the right time and the plots there did well. We till our summer plots under around Labor Day and plant horse feed oats.
This picture shows a plot that was hit hard by the deer in mid-late May. The plot died from lack of rain.
This is a plot of milo and clay peas in a good year. The peas climb the milo stalks.
