i have a patch of 1.5 acres… thats a mix of boulders/stones and soil; never been cultivated. I wanted to make a green cover on this patch. Thinking of broadcasting pellets of mix seeds - til (white and black); Legumes ( val and some beans) and pegion pea. maybe at end of rains i will treat it as a mulch for the ground and sow sorghum/juar around october? any thoughts?
