Can Winter Rye Choke Out Weeds?

Cooler weather has set in and your yard is awash with the green of the winter rye yard. The weeds appear to get swallowed up under the adult development of this lush green grass. There’s a clear relation between the kind of lawn you’ve got and also the decrease in unwanted growths. Areas of California and other states using mild winters — normally, U.S. Department of Agriculture plant hardiness zones 3 through 9 — may actually encourage this weed-deterring grass year-round.


There are two sorts of winter ryegrass. There’s the yearly variety which you want to replant every year and also the more permanent perennial kind (Lolium perenne). The grass germinates rapidly, within three to five days, and can efficiently cover an area within four to eight weeks. It provides a homeowner with a bright green yard, is great as a filler for bare patches, which can mix with additional ground cover varieties and aids with mud control. The weed-repelling capability, however, is one of the biggest advantages to planting this hardy grass in your yard.

Effect on Weeds

Winter rye grass is an excellent ground cover since it’s allelopathic — the grass contains a chemical which will naturally destroy certain plants and weeds which grow in the same soil. Ryegrass implanted in the yard can overcome weeds such as duckweed and crabgrass. Take care, however, as ryegrass may overcome other grasses planted in conjunction with it. For example, it can slow the development of Bermuda grass. Combat this by cutting the ryegrass closer to the ground and lowering the water volume at the conclusion of a cool season in preparation for the emergence of this alternate grass.

Grass Combinations

Gardeners will often plant ryegrass with other grasses to utilize this weed-deterring edge. This grass is usually created with zoysia, Bermuda grass and blue grass, depending on water available, kind of soil and yard look desired. The seed or sod is also applied to lawns to fill in bare or thinning areas, in addition to to take over when cooler weather halts the development of summer ground cover.

Ryegrass for a Weed

Not only can winter rye choke out weeds, but in addition it can turn into a weed itself. Rye grass could be resistant to herbicides and be tricky to remove from areas where it isn’t desired. Increasing the use of the herbicide glyphosate has been demonstrated to be somewhat effective in controlling the spread of this famous ground cover.
