What is Ryegrass?

Rye is a cool-season grass and is most often found in prairie and savannah regions. It can be used in a variety of applications, including erosion control, seeding on marginal land, and growing for hay or silage.

Rye has been used as a cover crop for more than a century. Cover crops are often sown in late fall or spring and then mowed at the beginning of the following year to provide an annual source of green material. They are usually sown in areas where there is little or no residual soil moisture, and then mowed or grazed through the growing season. The green material left after mowing provides a habitat for beneficial insects and other organisms.

A wide range of benefits have been reported from using rye as a cover crop, including improved soil tilth, decreased soil erosion, increased nutrient cycling, increased organic matter content, and reduced nitrate leaching. Rye is a cool-season grass; cool-season grasses are those that can be sown in spring, and grow well in fall. Let’s see how long it takes for ryegrass to grow.

Growing Ryegrass

Sow rye as soon as the soil can be worked

Sowing rye can be done by hand, or by machine. Choose a sunny, sheltered location where you can control the temperature of the seed. Rye is generally sown in fall and mowed in early spring. Sow the seed 2-3 cm (1-1 1/2 inches) deep, and at a spacing of 30-45 cm (12-18 inches). Cover the seed with fine soil.

Water the seed

Water the seed and press it down firmly to ensure that the seed is covered. It is not necessary to cover the seed with a seeding mulch, but it will help to keep weeds down. Rye is a cool-season grass, so it is best to water it only enough to keep the soil moist. If the soil is dry, it will cause the rye to bolt, and produce a large seed head.

Mowing the rye

Mowing the rye after germination will encourage a dense stand. The rye can be mowed at any time, but it should not be cut too short. However, a light cutting will encourage a vigorous stand.

Cutting when the plant is young will also reduce the weeds that spring up early. When the rye is about 12 inches tall, cut it back to 3-5 inches. The rye will regrow quickly and will provide a dense stand of green foliage for a few months. You can mow the rye as soon as it begins to grow again but leave it a little longer if you want it taller.

Insects and disease

Several pests will damage or kill rye. Let’s take a look at the most common culprits.


Caterpillars can eat the leaves of rye. They are most likely to do this in early spring when the rye is just beginning to grow.


Rye is not very attractive to slugs. They will usually not stay on the seedlings for more than a day or two. It is best to keep the grass free of slugs. If you find them on the grass, you can either remove them or spray them with slug bait.
