Crabgrass vs Tall Fescue: A Detailed Comparison

When it comes to maintaining a lush and healthy lawn, one of the most crucial decisions you’ll make is selecting the right type of grass. Among the various grass species available, crabgrass and tall fescue are two common choices that homeowners often consider. While crabgrass is notorious for being a weed, tall fescue is a desirable cool-season grass. In this comprehensive guide, we’ll explore the key differences between crabgrass and tall fescue, helping you make an informed decision for your lawn.

1. Growth Habit and Appearance

Let’s start by examining the growth habit and appearance of each grass variety:


– Crabgrass is an annual grass that germinates from seeds each year.
– It has a sprawling growth habit and spreads horizontally through its stolons.
– The leaves of crabgrass are wider than tall fescue leaves, often with a lighter green color.
– It can grow up to six inches tall and has a clumpy appearance.

Tall Fescue:

– Tall fescue, on the other hand, is a cool-season grass that is often grown as a perennial.
– It forms dense bunches with upright growth and does not spread via stolons.
– Tall fescue leaves are narrower compared to crabgrass, and they have a darker green shade.
– This grass variety can reach heights of up to three feet, providing a neater and more manicured look to your lawn.

2. Adaptability and Environmental Tolerance

Understanding how well each grass type adapts to different environmental conditions is crucial for maintaining a healthy lawn. Let’s explore the adaptability and environmental tolerance of crabgrass and tall fescue:

3. Maintenance Requirements

Keeping your lawn in top shape requires regular maintenance. Let’s compare the maintenance requirements of crabgrass and tall fescue:


– Crabgrass is a low-maintenance grass in terms of mowing frequency since it tends to grow taller and less dense.
– However, its aggressive growth pattern means that regular weeding and control measures are necessary to prevent it from taking over your lawn.
– Due to its annual growth cycle, crabgrass requires reseeding each year.

Tall Fescue:

– Tall fescue requires more frequent mowing compared to crabgrass, as it forms denser turf.
– It benefits from regular fertilization and watering but is generally less demanding in terms of weed control.
– Since tall fescue is a perennial grass, it doesn’t require reseeding each year, making it a long-term investment for your lawn.
