Answers To The Above Questions About Bermuda Grass
- The difference between hulled and unhulled - Hulled Bermudagrass
seed have had a "outer" seed coat removed by seed producers using mechanical
means, much like you remove a "jacket" when you come in from the cold.
This removed seed coat allows water to enter into the seed quicker than if the protective
jacket was still in place. The object of all this - removing the hull is to decrease
the time it takes for the seed to germinate. Resulting a a more quickly established
lawn. Both hulled and un-hulled varieties of the same seed variety, are the same
grass. The disadvantage is that if you do not have good
conditions for germination and growth (moisture, etc)... all the the little freshly
germinated seedlings may die. A seed coat is natures way of ensuring survival of the
species by spreading out the germination period. If you can provide good moist
conditions for your seed, hulled seed will germinate and establish a lawn the quickest.
If you are not sure, you might want to mix both hulled and un-hulled seed in your
planting. Or plan of providing good growing conditions with adequate water and
is definitely one of the better lawn grasses for HOT areas... You might want to
consider planting an improved variety such as Sahara instead of
the common variety... Bermudagrass handles heat well when grown, but it still needs
water. Keep in mind that you CANNOT establish seeds without constant (some times
twice daily) watering until after the seeds have sprouted and the plant has reached a
larger size where the roots can tap into deeper ground/soil water sources. This can
take 45-90 days or more to accomplish... then as the grass grows larger you can begin to
reduce watering to more normal levels for your area.
- Can I improve my common or
vegetative Bermuda by overseeding with an improved turf type?
Yes you can, The improved varieties can improve common bermuda
and the new Princess 77 variety can also improve many hybrid /
vegetative types. Planting around 1/2 to 1 lbs per 1000 sq. ft
can often lead to improvements in your stand of grass. Make
sure good seed / soil contact is obtained in any overseeding
What is recommended
seeding rate for new turf?
We recommend 2 to 3 lbs of coated Bermuda seed per 1000 sq. ft.
During the middle of summer you may can get by with less seeds as
germination is generally higher at this time provided that
irrigation is available. Plant a little heavier when you must
plant early or late in a season to compensate for higher
establishment risks. In most cases you should NOT exceed the 3
lbs per 1000 sq. ft. as it could result in too dense a stand which
can cause mowing and growth problems.
When and where can I plant
WHEN: Bermuda is best planted in late spring / early summer.
Do not plant until soil temperatures are 65 / 70 degrees or higher
in spring AND all danger of freeze / frost is past. If you
plant too early, you run the risk of the seeds being killed or not
germinating. For Fall plantings, do NOT plant later than 60
days before first expected frost in deep south or 90 days before
first expected frost in cooler areas.
WHERE: Bermuda should only be planted in full sun
areas, preferably on well drained soils. It is not very
tolerant of shade and areas less than 70% full sun will often thin
out Bermuda stands. Proper soil preparation and adequate
drainage is a necessity for successful healthy turf.
Should I cover the seeds after
Yes... Bermuda seeds need both a LIGHT soil covering and the ability
to receive sunlight through this covering in order to obtain good
germination. The ideal covering depth is 1/8 to 1/4 inch of
soil, with 1/8 inch ideal. Topdressings can be used, but care
must be taken not to exceed 1/4 inch of soil coverage. Raking
or dragging to cover lightly are also approved methods. It is
possible to plant too deep and NEVER have any seeds germinate.
Also... the seeds will NOT germinate just broadcast on top of the
How long does it take
for the seed to germinate and how long to create a lawn?
GERMINATION: Under ideal conditions, hulled seeds can
germinate within 3 to 7 days. IF conditions are NOT ideal, it
is quite normal for Bermuda seeds to take 14 to 21 days for
germination to occur. Occasionally it can take even
longer. Seedlings are very small when they first emerge
and require careful inspection to observe.
Under ideal conditions, it is possible for Bermuda's to
establish from seed within about 5-6 weeks to provide a limited /
usable turf. If planted later or earlier within the growing
season, it can take longer. For pasture purposes you should
allow growth to be about 8-10 weeks old before grazing. For a
fully established / multi-use turf such as a "perfect lawn" or
"tough" sports field, you need to allow for 2 growing seasons for
the Bermuda grass plants to fully mature to adult stage. Keep
in mind that these plants are teenagers the first year and thus not
quite as hardy or adapted as they will be after having two seasons
growth time to mature.
How much water & fertilizer is
needed on a Bermuda turf?
WATER: Exactly how much water is needed has not really been
quantified by turfgrass scientists. However in general,
bermudagrass will normally use much of any water provided.
Bermudas can go for extended periods of time without irrigation (60
to 90 days), thus their popularity as a drought tolerant grass.
The only drawback is they go off-color as they become dormant.
Most grasses need 1-2 inches per week to maintain a good growth. ---
Seeded bermudagrass areas should be kept moist for the first 2-3
weeks to ensure proper germination. This may require multiple
waterings each day to prevent the soil from drying out. Later
as growth occurs, you should switch to less frequent, more deeper
waterings. Bermuda is superior to many other grasses in
FERTILIZER: Always obtain a soil test each season or before
planting any new seeding of Bermuda. A pH test is also
recommended to make sure that the soil is in the best pH range for
growth (ideal 6.5 to 7.0).A balanced fertilization program
during active growth months with the correct amount of N applied
will provide a healthy turf. We do recommend a lawn starter
fertilizer during initial establishment.
Is Bermudagrass salt
Yes, Bermudagrass has very good salt tolerance. It is actually
one of the most salt tolerant grass species used.
Mohawk Bermuda Grass has been found to have the best
salt tolerance of the many seeded varieties we sell. In some
specific instances, with careful turf management, high salt water
has been used for a part of the irrigation needs for Bermudas.
- When can I mow my grass,
how high and do I need a special mower?
You can generally start mowing 3-4 weeks after seeding your Bermuda
lawn. Occasionally if growth is rampant, you may need to mow
within 2 weeks after planting. Thereafter, mowing will be
required in a range of 3 to 7 days depending on various factors.
Bermudas are mowed from around 3/8 inch to 1 & 1/2 inches in height.
Lower mowing requires more frequent mowing. Height below
around 1 inch may require a "reel" type mower to prevent scalping.
Heights of 1+ inches can usually be maintained with a rotary mower.
Height is a matter of personal preference. The newer /
improved varieties such as Princess generally look better than other
varieties when maintained at short heights. Common should
generally NOT be mowed below 1/2 inch. Lower mowed height will
require more maintenance and water monitoring.
- What about growing
Bermuda where the winter is cool? Can I overseed?
Bermuda goes DORMANT when temperatures start dropping below 65
degrees. Once a frost / freeze occurs the grass blades loose
their chlorophyll that keeps them looking green, resulting in a
dormant / brownish - tan color. The grass will remain this way
until extended warm temperatures return in late spring. The
only solution is to OVERSEED the Bermuda. It is NOT recommended that
a young first year stand of Bermuda be overseeded. You
should wait until the second year to overseed with a Ryegrass.
Cultural methods are needed to encourage the Bermuda to start
growing and limit growth of any ryegrass as warm spring temps
return. To overseed a Bermuda lawn, scalping and verticuting
are helpful methods in producing a good overseeded cover. Also
often a slit seeder (rental equipment) can help ensure the ryegrass
seed properly germinate.
