Interestingly, Ryegrass(Lolium perenne) and tall fescue(Festuca arundinacea) both are perennial cool-season grasses. Still, both have different properties in lawns. Because of being in the same season, people can't differentiate them. Although there are multiple differences in both types of grasses.
Let's understand those factors and try to figure out the difference between them.
Ryegrass Vs Tall Fescue in the USA
Although either ryegrass or fescue works better than any other summer season grass like Bermuda grass, centipede, bahiagrass, and zoysia grass in the cold season. If one has a choice between hot season grass vs fescue or ryegrass, one can go with either.
But if your lawn is in a cold climate, your selection should be based on their properties.
Following are the properties discussed that distinguish both ryegrass vs fescue grass-
Identification
Color, height, leaves shape, roots, and nature, are some identity factors to differentiate two different lawn types of grasses. The following comparison is based on these factors-
- Ryegrass
Ryegrass is slightly invasive in open fields and agricultural areas but in lawns, it is quite a thin turf.
Generally, Ryegrass appears in paint green color.
It can grow up to 1 to 2 feet in height and become ready for mowing when it becomes 6 inches tall.
Ryegrass leaves are very unique as they grow folded in their buds.
- Fescue
Fescue grass grows with fine thick sharp broad leaves that have a line pattern. Their general color is dark green and they can grow up to 3 feet tall.
In roadside or open fields, Fescue grass is invasive.
Traffic handling capacity
One of the most needed lawn grass quality should be its foot handling capacity. If lawn grass is sensitive to regular foot walking then it can be a reason for rejecting a particular lawn grass.
- Ryegrass
In the case of Ryegrass, you can keep yourself confident that it can handle family walking traffic regularly. It isn't that sensitive to the feet walking either humans or animals. But continuous rolling or jumping in the same place can increase the chances of damaging the turf.
If you just mowed your lawn, you should not allow heavy foot traffic immediately. After a while when Ryegrass becomes 3 to 4 inches tall, you can continue walking or running on turf.
- Fescue
Fescue grass can handle heavy foot traffic in most seasonal conditions. You can run, walk, or play on the Fescue turf without any grass sensitivity.
Still, be aware when you just irrigate your lawn turf or you may slip and can hurt yourself.
Climate conditions
Particular lawn grass is ideal for various climate conditions is it can grow in low maintenance, less sensitive to too high and too low temperatures.
- Ryegrass
Although Ryegrass is a cold-climate lawn grass yet it can grow in both cold and warm climates with proper care and maintenance.
Ryegrass can handle the higher temperature in the daytime up to 86 degrees Fahrenheit but more than that can affect the grass directly. In a cold climate, if your daytime is too cold less than 50 degrees Fahrenheit, then grass stop growing even being a cold climate grass.
Even Ryegrass can handle drought conditions for a few days without irrigation.
- Fescue
Fescue grass is a cold-climate grass as well and can grow in both cold and warm climates.
Unlike Ryegrass, Fescue grass can handle more dormancy conditions in odd climates. It can handle drought conditions more than Ryegrass.
In daylight, it can survive in high temperatures of up to 89 degrees Fahrenheit in warm regions, but in cold regions, it shouldn't be less than 53 degrees Fahrenheit in daylight.
Soil type and pH
Every lawn grass grows in specific soil and soil conditions. If soil pH is not remained according to grass needs then either it starts dormant or does not grow properly. But when we consider two different grass to compare, it is a point to be noted that they can grow in the least ideal soil conditions with more comfort.
- Ryegrass
Ryegrass need well-drained loamy soil to grow at its peak. Otherwise, it can grow generally in ordinary region soil too but at a less growing rate.
Soil pH should be 5.7 to 7.3 from acidic to alkaline.
Water-holding soil is not ideal for Ryegrass but if you manage the drainage of the lawn, you can grow Ryegrass in it too.
- Fescue
Fescue grass grows ideally in clay soil that contains high organic matter. Soil should have enough Nitrogen to grow Fescue grass in cold or warm regions as well.
Although it can grow in other soils too without managing its need, it is not suitable to say that it can grow everywhere in every type of soil.
Soil pH must be between 5.5 to 7.6 for Fescue grass.
Performance in warm climate summer
Many cold-season lawn types of grasses don't like sharp intense sunlight in a warm climate in summer, Most of the time they hesitate to adopt such conditions. If your region is very diverse according to climate, then you should keep this factor in mind too.
- Ryegrass
Ryegrass grows properly at a certain height of temperature. Even overirrigation doesn't work to keep it healthy if the temperature is too hot in the daytime. So, if your region reaches higher temperatures in summer(more than 86 degrees Fahrenheit), you shouldn't grow Ryegrass on your lawn. In that case, select ideal warm-season lawn grasses.
In normal temperatures in daylight(less than 86 degrees Fahrenheit), Ryegrass can grow in general conditions.
- Tall fescue
Fescue needs proper care in hot climates if daylight is too intense. Although it survives temperatures up to 89 degrees Fahrenheit, without proper care, it can't grow further.
Unlike Ryegrass, it needs less maintenance and care in summer. If the temperature reaches higher than its limit, it starts losing its color.
Maintenance
We consider lawn grass with low maintenance if it cost less in fertilization, irrigation, aeration, weeding, mowing, and other maintenance facilities. This also helps you to select lawn grass according to your daily schedule too. some of the best lawn maintenance services are TruGreen, Sunday, Lawn Doctor, Weedman, Scott lawn maintenance, etc.
- Ryegrass
Ryegrass need maintenance(very low than other cold-season lawn grasses except for Fescue) in both cold and warm climate. In cold regions, Ryegrass needs proper mowing, aeration, weeding, and fertilization during the green period. At the time of dormancy, it loses its capability of handling foot traffic.
Sometimes it consumes extra maintenance costs on weed killers, mowing, aeration, and fertilization. In hot regions, Ryegrass needs additional maintenance than Fescue grass.
- Fescue
Fescue grass doesn't need as much care and maintenance as much as other cool-season lawn grasses need. Its overall maintenance cost is too low and it can survive winter in common facilities too.
During summer, it doesn't need extra irrigation but needs regular mowing. Before going into dormancy, it needs one last aeration and fertilization to recover perennially.
