- Toughness. Fescue can handle many less than ideal conditions. Drought, traffic, and low fertility.
- High production. Feed tonnage is competitive with many if not all cool season grasses.
- Easy to establish. Fescue is easy to plant and grow.
- Good for erosion control. Fescue is resistant to flowing water
On the negative side:
- Toughness. Can reduce palitability.
- Endophytes. Endophytes are fungi that grow in the fescue and reduce its feed value.
- Ease of establishment can turn the fescue into something of an invasive species.
- Fescue is probably the worst habit of all the cool season grasses for wildlife.
- Low magnesium levels in fescue pastures and induce a fatal disease called grass grass tetany.
One of the positive aspects of tall fescue I have not mentioned is winter grazing. Fescue can be allowed to grow to its full height in the fall by deferring grazing. The Fescue becomes a standing hay crop that the cattle harvest themselves. The toughness helps it to hold up under traffic. And some really good news about winter grazing of fescue is that the cold weather improve feed value.
Jesse Bussard, wrote her Master's thesis on tall fescue include a summary on her blog. This part 1. Part 2. Part 3. And Part 4. If you are using fescue, you should read what Jesse has learned.
