Milton from Suffolk, Va writes
Blood Meal itself is a natural deer repellant. You can sprinkle the dried blood meal around the perimeter of the garden. If you live in a raining climate then you should use more than if you live in an arid region. Reapplication is neccessary after rainfall. Unfortunately, this is not a labeled use of the Hi Yield Blood Meal 12-0-0 so we can't advise of mixing it with ammonia.
