Rye Grass Overview

Secale cereale is commonly known as Rye grass, Forage Rye or Hungarian Grazing and is mostly grown by gardeners as green manure as part of a crop rotation plan. One of the best for growing over winter in almost all locations and soil types. It develops deep roots drawing up nutrients, holds the soil together and prevents nitrogen from being lost over the winter. An excellent weed suppressor, it emits a seed inhibiting chemical which can prevent the germination of small seeds. Crops planted afterwards may fail if this chemical s not allowed a month to disperse after being dug back in; however, it does not harm transplanted seedlings. Originating from Turkish area, Secale cereale has been harvested since Neolithic man, grown extensively as a grain crop, it has and still is, used for flour in the production bread, crispbread, beer, whiskey, vodka's and as animal fodder. It is high in carbohydrates and survives where other grain crops such as barley and wheat will not.
