Kentucky bluegrass and tall fescue are both popular grass options for lawns and landscapes, but they do have some notable differences. As a gardening and landscaping expert, I can provide you with a detailed comparison of these two grass types.
1. Growth Rate: One significant difference between Kentucky bluegrass and tall fescue is their growth rate. Tall fescue has a higher growth rate, which means it tends to grow faster and requires more frequent mowing. A typical mowing schedule for tall fescue is every 5-6 days, while Kentucky bluegrass can be mowed on a weekly basis.
2. Mowing Height: Mowing height is another aspect where these two grasses differ. Tall fescue is often recommended to be maintained at a height of 3 inches, which helps to minimize weed problems. On the other hand, Kentucky bluegrass can be mowed slightly shorter, around 2-2.5 inches, without significant issues. However, it’s important to note that lowering the mowing height for tall fescue may increase weed pressure.
3. Weed Tolerance: Speaking of weed pressure, tall fescue generally has better weed tolerance compared to Kentucky bluegrass. When maintained at a height of 3 inches, tall fescue tends to form a dense turf that inhibits weed growth. However, if the mowing height is lowered, the weed pressure may increase, especially in improved varieties of tall fescue.
4. Drought Tolerance: Tall fescue is known for its excellent drought tolerance. It has a deep root system that allows it to withstand periods of dry conditions better than Kentucky bluegrass. This makes tall fescue a popular choice for areas with limited water availability or during hot summer months.
5. Shade Tolerance: While both grass types can tolerate some shade, tall fescue generally performs better in shady areas compared to Kentucky bluegrass. Tall fescue has a more robust shade tolerance, making it suitable for lawns with trees or buildings that cast shadows.
6. Appearance and Texture: Kentucky bluegrass has a fine texture and a lush, dark green color, which many people find aesthetically pleasing. Tall fescue, on the other hand, has a coarser texture and a lighter green color. The choice between the two may depend on personal preference and the desired appearance of the lawn.
Kentucky bluegrass and tall fescue have differences in growth rate, mowing height, weed tolerance, drought tolerance, shade tolerance, and appearance. Understanding these distinctions can help homeowners make an informed decision about which grass type is best suited for their specific needs and conditions.
