Sorry if this is in the wrong section but I’m looking for options for a cover crop to put on some fallow land that didn’t get sown with winter beans last autum. Half the field is beans so I’m looking for something to sow that will be deep rooting like the beans. Not mustard as possibly still got osr in the rotation. Also when is best to sow the cover crop? Land is medium to heavy and main weeds are crainsbill small amounts of blackgrass. Thanks in advance ben.
