Choosing the right turf grass for your lawn is crucial and it affects long-term maintenance costs, durability, water usage, and appearance. You also need to consider whether the chosen turf is suitable for the regional climate. For both residential and commercial landscaping, you can choose from varieties like Marathon Grass and Fescue Grass. They have some common characteristics, but the difference in aesthetics, performance, and adaptability can vary based on geographic location.
Getting The Basics Clear
Fescue grass is a type of cool-season turf grass that has many variants like Hard, Fine, and Tall Fescue. It is known for qualities like fine texture, adaptability, and durability. You will find Fescue varieties being used commonly in residential lawns, public parks, and sports fields in the U.S. and Europe.
Marathon Grass is a proprietary sod product developed by Southland Sod Farms. It is based on the turf-type tall fescue variants. It has three subtypes, Marathon I, II, and III. Each variant has unique water needs, and their growth speeds and textures are also different.
Climate Suitability
Marathon sod performs best in USDA Hardiness Zones 8–10. It is ideal for regions like Central Arizona, Southern California, and parts of the Southwest. It thrives in warm temperatures but should not be chosen for extreme desert heat without proper irrigation.
Fescue grass is ideal for cooler climates. You can pick it without concern for regions like the Midwest, the Pacific Northwest, and Northern California. Traditional tall fescue varieties can tolerate heat but they do not match the Marathon cultivars.
Water Needs
Water conservation is critical in drought-prone regions like California. Marathon III can use water more efficiently thanks to its rhizomatous growth system. It also copes better with heat stress compared to other tall fescue sod types.
However, both tall fescue and Marathon sod are classified as moderate water-use turfgrasses. During the peak summer months, they require around 1–1.25 inches of water per week. They sit below Kentucky Bluegrass but above Bermuda or Buffalo grass in terms of water consumption.
Texture And Visual Appeal
Choose Marathon III if you want your lawn to have a strong visual appeal. It has a lush green color, a fine-bladed texture, and uniform density. This combination makes the grass perfect for commercial landscapes as well as premium residential lawns that prioritize visual appeal.
Marathon I is coarser and therefore better suited to areas with high foot traffic, while Marathon II strikes a middle ground.
Traditional tall fescue seed blends vary significantly, based on the variety chosen. While many have a pleasing texture, they cannot match Marathon III in terms of consistency.
Maintenance Needs
In terms of maintenance, Marathon III requires moderate mowing as it grows rather slowly. You can mow it once every two weeks during the growing season. Marathon I, on the other hand, grows more aggressively and may need weekly mowing.
Tall fescue grass needs more attention during its establishment stage and it stabilizes when you provide proper watering and fertilization. Dwarf fescue varieties require a lower mowing frequency.
Traffic Tolerance and Recovery
Marathon I is very well suited for high-traffic environments. It can be used confidently in backyards frequented by playful kids and pets. The aggressive growth supports a fast recovery rate.
Marathon II and III have moderate to high durability. However, the latter has a finer texture and may not cope well with heavy traffic.
Tall fescue seed blends fare well in wear resistance, but damaged areas do not self-repair unless you reseed.
Pest And Disease Prevention
Both fescue grass and Marathon cope well with common turf diseases, especially when compared to cultivars like bluegrass and ryegrass. However, they may still be affected by conditions like fusarium blight, brown patch, and red thread etc. This may occur due to the application of excessive nitrogen fertilization during hot, humid periods.
Marathon III’s dense growth rate helps it combat weed invasion and pest infestations. Regular aeration and proper irrigation help the cultivar cope well with disease risks.
