A tip for gardeners especially in the orchard is to grow fescue and rye. Grow one crop only and kill it back with the vinegar herbicide mix. These cool season grasses give off their own allelopathic “herbicides” without hurting the crops. Michigan State has worked with rotations of ryegrass and sorghum for weed control in the vegetable g garden. Vinegar herbicide again is used to kill it down before the vegetable planting. Rye helps greatly with early season ragweed and common lambsquarters.
