Fescue vs Bluegrass Identification
Let’s briefly describe Tall Fescue and Bluegrass so that you can quickly recognize the turf type before we get into more detail about their differences.
1. Kentucky Bluegrass
Kentucky bluegrass, commonly known as poa pratensis, is a kind of meadow grass indigenous to areas of Europe and northern Asia. However, it is one of the most popular grasses used in backyards with cool-season conditions in regions like Kentucky and Virginia, where it is often cultivated for fodder. It is a perennial grass that will return each year and flourish in the spring and fall.
With medium-to-dark green leaves that are smooth and soft to the touch and have a V-shape, Kentucky bluegrass may reach a height of 20 to 24 inches.
2. Tall Fescue Bluegrass
Tall Fescue (scientific name: Festuca arundinacea) is another choice for lawn grass among many homeowners, largely due to its toughness and resistance to wear and tear, particularly under conditions of heavy foot traffic. Unlike other grasses, which form sods and spread by themselves, this deep-rooted perennial grows in bunching clusters. Like Kentucky Bluegrass, this kind of grass is well-liked in colder climes and grows more rapidly in the cooler spring and fall months.
Wide leaf blades with equal-sized veins and a medium-coarse texture are characteristics of tall fescue. This specific grass is a medium-green tint that can occasionally take on a bluish-green look.
Which is Better Tall Fescue vs Bluegrass?
Which grass is best for your lawn, you might be asking now? The basic answer is that tall fescue and Kentucky bluegrass are both cool-season grasses. Both bloom in the United States’ northern areas. Both have unique aspects as well. However, after reading about the advantages and disadvantages of these grasses, you’ll be in a better position to make a choice.
Pros and cons of Kentucky Bluegrass
- Rhizomes are formed as it grows, and it covers bare places on their own.
- It does well in the United States’ extremely cold northern regions.
- It handles foot traffic effectively.
- Kentucky bluegrass thrives in full sun and mild shade, adapting well to most environmental factors.
- Rhizome growth allows it to spread far and recover quickly.
- In comparison to Tall fescue, it needs more nitrogen fertilizer.
- It goes dormant during the summer season.
- It also spreads in places where it was not meant to because of sod development.
- In hot temperatures, it is vulnerable to weed invasion and illness.
- Bluegrass will fall dormant and lose color in hot, dry conditions that last a while.
Pros and cons of Tall fescue
- Even in warmer weather, it doesn’t go dormant.
- It grows in clusters rather than spreading like bluegrass.
- It thrives in gloomy environments and is shade tolerant.
- Per 1000 square feet of lawn, 1 kg of nitrogen fertilizer is necessary.
- Both the north and south of the United States are good places for it to grow.
- The main drawback is that tall fescue doesn’t cover up barren spots in your lawn because of its deep roots and vertical bunched growth style. Reseeding is needed to achieve this goal.
Difference Between Tall Fescue and Kentucky Bluegrass
The following table shows the difference between tall fescue and Kentucky bluegrass:-
|Tall Fescue||Kentucky Bluegrass|
|For every 1000 square feet, tall fescue needs one pound of nitrogen fertilizer.||Per 1,000 square feet, KBG needs 3 to 6 pounds of nitrogen.|
|Grows bunchy sods and is more resistant to traffic.||Produces thick sods but is less tolerant of road stress.|
|Tall fescue can take little shade, but it needs four hours of intense sunlight to live.||KBG can thrive in the shade, but it needs at least eight hours of direct sunlight to survive.|
1. Uses of Tall Fescue and Bluegrass
When turfgrass must withstand a lot of wear and tear, tall fescue is the grass of choice. This implies that it is seeded around walking pathways, in parking lot medians, baseball field stands, and animal pastures. In addition to withstanding traffic, it also fared better than many fine-bladed grass varieties in low nutrition, soil compaction, and high contaminant levels.
However, in a different context, Kentucky bluegrass is also suitable for busy areas. A substantial root and rhizome system is produced by Kentucky bluegrass. But there can be issues with cutting and diffing. As a result, Kentucky bluegrass is perfect for golf courses, sporting fields, and high-traffic lawns that require a smooth feel.
2. Water Requirements of Tall Fescue and Bluegrass
Tall fescue and Kentucky bluegrass have different water requirements depending on the weather. Both grass varieties typically need between 1 and 1 1/4 inches of water each week. Tall fescue, on the other hand, has deep roots that can access deep soil and draw water from there. Every week, 2 inches of water are required for the Kentucky bluegrass. However, in the summer, it needs two and a half inches of water, and in hot weather, it becomes dormant. If your grass has sandy soil, it needs 1/2 inches of water every third day.
3. Ph and Soil Types Requirement for Fescue and Bluegrass
An ideal pH range for tall fescue is between 5.5 and 7.5. The best results are obtained when planted on damp, rich clay soils. Some plant and grass species may even be unable to establish roots due to the extreme compaction of the soil. Tall fescue spreads by growing new clumps of grass at the ends of stiff stolons that it sends out into the surrounding soil, whether compacted or loose.
Kentucky bluegrass prefers soil with a pH between 6 and 7. The best soil for Kentucky bluegrass is either rich and moist or well-drained. Once planted, it may even survive for extended periods in muddy circumstances since its root system, and rhizomes will help maintain the grass in the place.
4. The Durability of Bluegrass and Tall Fescue Grass
The hardest grass you may select for a lawn is tall fescue. It is tough to muddy circumstances, animal damage from digging, compacted soil, and foot activity. It also has exceptional resistance to insects, molds, mildews, and other typical lawn diseases. It fills in any bald spots fast and establishes itself swiftly.
Kentucky bluegrass tolerates foot activity and mucks well, too. It has a comparable resilience to illnesses and insects and may recover from digging animals. However, kent recovers from diffing and cutting more slowly than tall fescue and needs more moisture and nutrients. It also resists pollutants well, but not as well as tall fescue.
5. Shade and Sunlight Requirement for Fescue and Bluegrass
However, the part sun is ideal for tall fescue since it does so well there. It may also flourish in full light in colder climates. High temperatures, however, can make tall fescue’s ends seem “burnt” or “rusted” if the necessary moisture levels are not kept, and the grass is exposed to direct sunshine.
Similar to other grasses, Kentucky bluegrass grows most quickly between 60 and 70 degrees Fahrenheit. If the temperature is constantly below 50°F or over 80°F, it will go dormant. However, like the sun, Kentucky bluegrass performs best in direct sunshine while it can tolerate brief periods of shadow.
6. Diseases and Pests affecting Fescue and Bluegrass
Neither tall fescue nor Kentucky bluegrass is more prone to pests, animals, or illness than the normal turfgrass you can get rid of those pests like grubs and worms by spraying homemade insecticide on grass. They also have higher than usual resistance and recovery rates. But tall fescue will bounce back quicker and with fewer resources than Kentucky bluegrass.
7. Mowing needs of Tall Fescue and Kentucky Bluegrass
During the cool seasons, tall fescue has to be mowed once a week to a length of roughly 2 inches due to its usual growth rate. If the weather is dry, mowing might only be necessary once or twice each month after temperatures reach an average of 85F or above. The probability of “burnt” ends is decreased in hot weather by trimming the grass to a height of 3″.
With no negative effects, Kentucky bluegrass can be mowed as short as 1″ or as high as 3″. However, the shorter it is, the more frequently it will need to be mowed for an even appearance—up to twice a week—because this grass species grows quickly throughout the chilly season. If trimmed shorter than 2 inches, a Kentucky bluegrass lawn also needs numerous annual dethatching.
