The pros and cons of ryegrass must be understood by any lawn owner who plans to use it as the main grass in the yard. Even though there are several attractive benefits that ryegrass can offer, such as being a rapid grower, inhibiting weed growth, and easily adapting to sun and shade, it also has a number of drawbacks, including requiring high maintenance, being susceptible to diseases, and having a tendency to be invasive.

_Weighing the Pros and Cons of Ryegrass

Understanding the positive and negative sides of using ryegrass will aid you in deciding if this is the correct type of grass for your lawn. Read on to discover more about the good and bad sides of ryegrass!

Advantages of Growing Ryegrass on Your Lawn

Some advantages of growing ryegrass on your lawn include its fast growth, high damage tolerance, and its great adaptability to sun and shade.

You can decide if this grass is the best variety for your lawn by understanding its main advantages and disadvantages.

There are advantages and disadvantages to using perennial ryegrass for your lawn. Contrary to annual ryegrass, which is occasionally used to add color to warm-season lawns in the winter, perennial ryegrass is utilized as a year-round lawn, or what is known as the main type of grass.

Let’s begin by going over the advantages.

– Fast Growth

Perennial ryegrass is one of the fastest-growing lawn grasses. With the right soil and sufficient moisture, the germination period for ryegrass can be between 5 and 10 days. Sometimes, it can pass through the sprout and seedling phases quickly. In fact, ryegrass germinates in an average of just 3 days.

Perennial ryegrass can develop from seed to mowing-ready lawn in less than 23 days if the growing environment is favorable. This implies that it may take as little as 3 to 4 weeks for your lawn to be filled with it.

Due to this, ryegrass is a great solution if your lawn has bald spots or you have a newly constructed home that needs a grass variety that will grow soon. In addition, you can incorporate it with your existing grass to give it a more textured and fuller look.

– High Damage Tolerance

Ryegrass has a great tolerance for wear, in contrast to other types of grass. Even when exposed to heavy traffic, ryegrass may keep its quality. Due to its quality, it is utilized on tennis courts and golf courses.

Benefits and Drawbacks of Ryegrass

It can manage traffic from cars, animals, and people, thanks to its fine-bladed characteristic. As a result, it is appropriate for busy or often visited locations like sports fields, parks, and recreation zones.

Due to its rapid growth rate, ryegrass will most likely fill in within a short period of time if it is damaged or if a portion of the lawn is removed. Ryegrass is extremely tolerant of damage and can recover almost immediately.

– Can Easily Adapt to Sun and Shade

While the majority of lawn grass varieties can thrive in the sun but struggle in the shade, ryegrass is so flexible that it can be cultivated in both full sun and shade. It enables gardeners to choose the right type of soil to grow in order to get the desired results.

Given that this grass is highly adaptable, it is a great choice to keep your lawn lush and healthy, even if there are trees shading the area.

– Can Inhibit the Growth of Weeds

Thanks to its ability to grow rapidly, ryegrass can easily outgrow lawn weeds. Aside from this, it can release allelochemicals, which can stop the growth of other plants. This amazing plant can effectively send a chemical signal that inhibits the growth and germination of surrounding plants. This is a great advantage, especially against a wide variety of weedy grass species.

Because of this, you can lay low on the herbicide use for your lawn, as ryegrass will do the job of providing your lawn with a natural defense against unwelcome plants and prevalent weeds.

– Versatile Height Range

Depending on your preferences, you can grow ryegrass into a longer or shorter lawn. While other lawn grass varieties have recommended growth heights, ryegrass can be mowed as short as 1.5 inches without suffering or feeling scalped, or it can be allowed to grow as tall as 3 inches, especially during the hot season so that it can retain moisture.

– Helps Prevent Soil Erosion

Another great advantage of ryegrass is that it has a deep root system, and thanks to its rapid growth, it can produce more roots in a short time, which will then be deeply embedded in the soil. The soil is then kept together by the roots, preventing water from washing it away.

Advantages and Disadvantages of Ryegrass

Ryegrass not only prevents erosion but also increases the nitrogen content of the soil. As it dies, it produces organic matter, which improves the soil’s health. The deep roots also mean it can get the soil’s nutrients and water, which makes it a nutritious grass that is excellent for animals. It can even endure grazing, which makes it a favorite among farmers for pastures.

Additionally, ryegrass improves soil aeration by breaking down the hard soil surface with its root system, which leaves tiny holes for air to pass through. As you may already be aware, compacted soil can limit plant growth by causing lawn fungus due to inadequate drainage.

– Drought Tolerant

Given that ryegrass has deep roots, it has the ability to access deeper water sources, which enables it to withstand drought to some extent. It can remain green and healthy even during brief periods of no rain. For this reason, it is an ideal choice for lawns located in drier climates.


The disadvantages of growing ryegrass on your lawn include its high fertilizer cost, allelopathy, the difficulty to eradicate it, and its high maintenance requirements. Now that we have discussed the benefits, let us take a look at all the main drawbacks of using ryegrass on your lawn.

– Requires High Maintenance

Given that ryegrass grows rapidly and has great recuperative abilities, it can absorb and use twice as much nitrogen compared to other lawn grasses. Without sufficient nitrogen, your ryegrass can turn pale and unattractive.

The Pros and Cons of Ryegrass

Because of this, it requires more work to maintain. Make sure that your lawn has enough nitrogen for your ryegrass to have that lush, green appearance.

– High Fertilizer Cost

With the high maintenance it requires, consistent fertilizer is part of this care, which may get very expensive very quickly. Ryegrass must be cut frequently, watered on schedule, and fertilized regularly to maintain the neat, crisp appearance that everyone enjoys.

– Allelopathy

Allelopathy is seen as a big advantage of ryegrass as a weed-inhibiting property, but it also suggests that any grasses or grass-like plants you want to plant next to it may experience growth challenges.

Ryegrass is a very competitive grass; thus, cultivating other grasses with ryegrass will be challenging. Other turf grasses won’t develop well around it because of its quick development. They may even perish from a lack of sunlight, water, and nourishment.

– Difficult To Eradicate, Especially in Spring

Ryegrass is exceedingly challenging to get rid of without the use of strong, indiscriminate chemical pesticides. Given that it is one of the hardest grasses to completely eliminate, it is advised that you plant it in areas where not many other types of grass can grow.

During springtime, when the weather is warmer, some species of ryegrass adapt even better, making them difficult to get rid of. The reason for this is that ryegrass develops in clusters, and these clumps quickly produce seeds. The ryegrass seeds would have sprouted in a matter of days due to their quick germination rate. Typically, breaking this loop is challenging and exhausting.

– Invasive Species

Remember the first advantage of ryegrass listed here? It grows at a rapid rate. That can be considered both a good and bad trait. If it is not kept up, the grass can be quite invasive.

Benefits and Limitations of Ryegrass

It is able to outrun almost all plants in its path due to its extensive root system and quick development. If a deep, solid weed or grass barrier isn’t employed as a border, it also has a tendency to encroach over flower beds, gardens, and other landscaping.

– Can Grow To 2 Feet Maximum Height

Ryegrass may reach heights of up to 2 feet, while other lawn grasses are limited to 10 to 12 inches. If it is neglected and not kept up with, you might not be able to cut it with a standard lawnmower, so you might need to rent a brush mower or other specialized equipment.

– Susceptible To Extreme Temperature

All varieties of ryegrass are selective to weather temperatures and cannot withstand extreme cold and heat. Winter ryegrass will be okay in moderate temperature, but a prolonged, cold winter will have your ryegrass die or suffer damage, especially for older grass with reduced cold tolerance.

Likewise, if the temperature exceeds 100 degrees Fahrenheit for several days, your grass will also start to turn yellow or brown.

– Susceptible to Diseases

Diseases can cause a lot of problems for ryegrass, particularly fungi-related diseases. Brown patches, lawn rot, and leaf spots are the most typical issues with this kind of grass.

– Requires a Lot of Water

Growing ryegrass requires a lot of water, so you need to frequently water your lawn. Even though they are considered a more drought-tolerant plant compared to other lawn grasses and can survive hot and dry climates, they cannot survive without a lot of water for too long.

Making an Informed Decision

Your soil won’t be able to absorb all of the water you add if it becomes broken and dry. Therefore, you should turn on your hose at full blast to try to fill up the cracks when your soil becomes dry and cracked.

– Regular Overseeding

Most of the time, ryegrass will grow in clumps if not regularly overseeded. Consequently, your lawn will have an inconsistent appearance, with some bald spots and areas covered in grass. This might give the impression of neglect as if you are not maintaining your lawn properly.

– Stiff Stems

Given that ryegrass stems are stiff, they might be difficult for your lawnmower blade to cut through, especially if it is not properly sharpened. Prior to mowing your lawn, ensure your mower blade is correctly sharpened to cut ryegrass effectively.

– Proper Mowing Is Needed

Another disadvantage of ryegrass is that regular mowing is required; otherwise, your lawn will have grass that grows out of control. The robust ryegrass can be mowed by a dull mower; however, it will leave your lawn looking patchy. The solution to this is to mow a little higher than usual, and mow twice at slightly different heights, especially if the grass is particularly dense.

Understanding the Pros and Cons of Ryegrass

However, it does not mean that you need special ryegrass blades to cut the grass. You can get the blades advertised as “dual action,” that is, it spins both ways. These kinds of blades will perform better than standard blades, although they are a bit pricey.


Any lawn owner who intends to use ryegrass as the primary grass in their yard should be aware of its advantages and disadvantages.

Here is a summary of all the key points we discussed:

  • Perennial ryegrass is different from annual ryegrass, which is occasionally used to add color to warm-season lawns in the winter. Perennial ryegrass is utilized as a year-round lawn.
  • One of the most notable characteristics of ryegrass is its rapid growth rate, which can be seen as both a good advantage and a disadvantage.
  • Some of the advantages of ryegrass are that it has a high tolerance to damage, making it suitable for high-traffic areas, it has weed-inhibition ability, it helps prevent soil erosion, it improves the quality of the soil, it adapts to sun and shade, and it can be grown to your desired lawn height.
  • This grass is also preferred by farmers for pasture use as it can be easily digested and is nutritious for horses, deer, and cattle.
  • The disadvantages of perennial ryegrass include being invasive, requiring high maintenance and fertilizer costs, and being susceptible to extreme weather temperatures.

Now that you know all the pros and cons of perennial ryegrass, you can make a sound decision about whether or not you can have this variety of lawn grass in your yard.
