Mowing will be required frequently on grounds with good moisture levels to maintain the fast growing rye in a more even lawn appearance. Water extensively in dry seasons where rainfall is not adequate. When annual rye is sown at the heavier seeding rate the grass can usually compete with the weeds if the weeds were removed in the preliminary stage of lawn preparation. This is a fast growing bunching grass and needs a consistent amount of nitrogen. This is not ideal but it is an easy way to remember and apply as the fertilizer directions state.
Fertilizer needs to be applied every four to six weeks during the growing season only.
In mowing or haying, fertilization usually follows to stimulate lush regrowth. Soil tests will help to determine the amount of fertilizer that is needed. Never over fertilize as excessive runoff and land or water pollution will be the end result. Lime will help any plant that needs it to assimilate as much of the fertilizer components as possible without wasting so much. Perennial Ryegrass Lawns require frequent mowing to keep up with the growth and can be mow quite close.
