Cover crops for dahlia beds
I am wondering if anyone has ever used cover crops for there dahlia beds? We always add manure/compost mixture to our dahlia areas but we are currently just growing to many to produce enough good compost and are hoping to expand even more next year. I am doing research on cover crops but many of the ones I am finding are saying you need to spray with a herbicide than till in. We are organic so I am not interested in spraying. We are hoping to find something that we can start growing between the rows early and either till in late fall or early spring. Any advice would be greatly appreciated.
