| Maintenance: The addition of top dressings
is frequently needed for the best results in growth. The bent grasses form thatch and when
properly removed helps to keep some of the diseases in check and must be done on a regular
basis. On golf courses and athletic fields the accuracy of watering and the qualities of
the soil must be closely regulated for the longevity of the turf which is under continual
use. |

Penncross Creeping Bentgrass |
Bent grasses are slower to return from damage
and may need additional grasses over seeded until the growth has returned to
the original density. The bent grasses require well draining soils and on many golf
courses sand is added to maintain good drainage. Each variety retains particular qualities
for climate, salt tolerance, color, texture, fertilizer needs, watering, and disease and
insect tolerance.
Maintenance requirements of Colonial bent
grass range from low to medium when grown in the north for lawns and higher if used for
golf courses or athletic fields where higher degrees of fertilization, watering, and
mowing are finely regulated. Maintenance requirements are extremely high in areas of heavy
traffic and where fast repairing of the turf is needed and if the grass is grown out of
the original habitat area.

MANAGEMENT PRACTICES
FOR CREEPING BENTGRASSES
MAINTENANCE: .Intensive management of watering to
the degree which the soil holds, mowing, reseeding if needed with disease and pest control
programs.
WATERING: requirements are light but frequent because of the
shallow root system to keep seedbeds continually moist.
ESTABLISHMENT: Mulch is sometimes applied to keep the seedlings moist until they
are established.
FERTILIZATION: Fertilization is frequent with a starter for seeds followed by an
application one month later and on a ten-day basis with soluble fertilizer until greens
have established.:

SUGGESTIONS FROM Tee-2-Green
Management Practices that have Proven Successful
on the "A" and "G" Series of Creeping Bentgrasses
It has been stated these grasses are different and not to be
managed as other bents are. Summarizing this, it means less
fertilizer, less water, less babying than the old bents that
superintendents are accustomed to. Summation of this is it also adds
up to less worry. These bents are tough, useful grasses that require
different management but overall the management is actually easier
than the superintendent is accustomed to. The end result is a very
high quality putting green surface that thrives on low mowing and
culminates in a near perfect putting surface with no grain and no
extraordinary practices other than the management mentioned below.

The formulations and rates may need to be adjusted
according to soil test results and turfgrass performance. After the
turfgrass has grown in fertilizer application should be kept light
and infrequent. This can be accomplished by the use of a fertigation
system or use of a soluble product applied with another product.
The amount of the fertilizer should be .1 of a pound of nitrogen
maybe every 14 days +/-, depending on growth, clippings and
performance. The yearly amount of nitrogen will be from 2 to 4
pounds, phosphorous 2 to 3 pounds, and potassium 6 to 10 pounds. As
far as micronutrients amounts this should be checked with tissue
tests during the year and again with a soil test in the early
spring.
Maintenance Program
The first mowing should be when there is uniform turf coverage
with a height from 1/4 to 3/8 inch and definitely not more than a
1/2 inch. The mower should have a smooth front roller. It has been
reported that some people have used grooved rollers to early.
Clippings should not be caught early on as this will help build a
biomass or padding that will protect the plant from damage. During
the early stage it is important to do weekly light topdressing. This
will cover the clippings early on, smooth any roughness in the
surface as well as accelerate the filling in of the turf grass
canopy. It is possible to get to desired mowing height within 6 to 7
weeks after first mowing if not sooner. The Penn A-4 is being
maintained by most facilities at 3/32nd or 9/64th.
It is important to irrigate only when necessary and when required
to fill the soil profile to field capacity or like trying to flush
salts from the soil profile. This could be a 30 to 40 minute cycle
depending on the type of irrigation used or time of year. Do not
irrigate the next few nights with a 5 or 10-minute cycle. Stretch
the time between irrigation cycles as long as possible. Again, this
will vary from the time of year, should be able to go at least 4 to
10 days or longer and only need to hit hot spots.
As far as aeration, this has varied from course to course.
Most golf courses aerate two to three times a year. Once in the
spring, early summer and fall, similar to what is currently being
done other bentgrasses. I have some courses going less others a
little more, all depends on the size of the greens, soil type and
traffic.
Topdressing varies depending on management style from light
weekly applications to once a month when verticutting. As with all
bentgrasses it is important to get as much topdressing into the
canopy as possible. This is can be only accomplished if the canopy
is opened up by the use of groomers, verticutting, grooving or
spiking.
