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.
Turf-Type Tall Fescue lawn renovation
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.
Spot-Seeding a Lawn
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.
