Grass seed mixtures
Grass seed is
often sold in mixtures of different types of grasses. A mixture of
Kentucky bluegrass, perennial ryegrass and fine fescue is often sold
as "Penn State Mix." (Penn State University DOES NOT sell grass
seed). This creates a diverse lawn where one variety may be affected
by a particular insect or disease problem while the others are
fescues are generally sold alone or with no more than 5 percent to
10 percent Kentucky bluegrass to help the lawn knit together faster.
It is not recommended for use with perennial ryegrass.

some perennial ryegrass in the seed mixture
Tall fescue has
been used in
low-maintenance situations because it tolerates poor soil
(although it requires well-drained soil), has good wear tolerance
and is drought tolerant once it is well established due to its
extensive root system. It is commonly used to reclaim strip-mined
areas. It is more shade tolerant than Kentucky bluegrass or
perennial ryegrass, although not as shade tolerant as fine fescue.
It does not require as high a level of
fertility as Kentucky bluegrass or perennial ryegrass. The newer
varieties of turf-type tall fescue have good color and density, too.

downside, it takes time to fill in because it is a bunch-type grass.
A new tall fescue lawn knits together as the clumps increase in
diameter, which can take a full growing season. It is also
susceptible to winter injury as you go north in Pennsylvania,
particularly when we have cold weather without snow cover. And even
though the turf-type varieties are more refined than the straight
species, they still look quite coarse when compared to Kentucky
bluegrass and perennial ryegrass. They are not for everyone.
