Establishment Of
Zoysia Grass Seed
(Including Compadre)
Note: These instructions will apply to
most seeded zoysia grasses including Zenith & Compadre Zoysia grasses. In addition to reading this
information page on establishment. Be sure and read our general
planting guide for zoysia seeds.

About Zoysia Seed:Most of the Zoysia grass seed sold
worldwide has been pretreated, or primed, to improve the germination
percentage and speed, by breaking the natural seed dormancy. This is
true for the improved turf-type varieties, as well as the numerous
branded versions of common Zoysia japonica from Asia. Occasionally,
with some of the newer turf-type varieties, this seed treatment is
not needed based on lab test results.

ALWAYS PLANT
ZOYSIA SEEDS SHALLOW !
(1/8 to 1/4 inch coverage)
They must have light to germinate properly.<<< Zoysia at 6
weeks. |
Zoysia grass seed offered for sale, whether
treated or not, should have a germination percentage over 75% to
produce good results on a turf project. Pretreated/primed seed
should be planted the same season, not stored for extended periods
of time. Zoysia grass seed is occasionally offered for sale as coated seed, with approximately 50% purity (Compared
to 98% on uncoated). These "pelleted" seed are generally
less expensive, and can produce satisfactory results if planted and
watered correctly. Currently the varieties available at
Seedland are usually un-coated, but this can change from time to
time depending on seed availability.

SOIL PREPARATION: Cultivate your soil to
6 inches, incorporating lime, any organic soil amendments and
pre-plant fertilizers as needed or based on soil tests. Zoysia grass
performs best under neutral to slightly acid pH conditions.
Prepare a medium-fine, firm seedbed - using a light roller on the
finished seedbed is beneficial to level and firm the area.
INFORMATION ON SEEDED
ZOYSIA GRASS:
SEEDING AND IRRIGATION: Zoysia grass seed
should be planted in late spring or early summer when nights are
warm and daytime temperatures are consistently over 75 deg F (24
deg C) - a warm soil temperature over 70 deg F will produce the
best results. Do not seed after mid-late
summer, or the slow growing plants will not be well enough
established to survive the first winter. Plant 1-2 pounds of good
quality raw zoysia seed per 1,000 square feet. Cover the
seed very lightly with soil by raking or rolling the turf area.
| SEED USE
NOTICE: Please note that we ONLY
recommend Zoysia seeds for use in bare soil areas.
Planting seeds into existing grasses has a HIGH
FAILURE rate. If planting into an existing lawn (grass and/or weeds) we recommend that you consider using Zoysia grass plugs instead of
seeds. - Zoysia seeds also are difficult to achieve
germination in low light / shady areas. Use plugs in
these areas for best results. |
A Brillion seeder also works very well,
if the seed is planted shallow. Zoysia seed must be planted near
the soil surface as it requires exposure to some light to
germinate properly. A thin layer of mulch or straw can be
beneficial in retaining soil surface moisture during germination.
Depending on rainfall, irrigate the zoysia seed lightly several
times a day to keep the soil surface continuously moist for the
first two to three weeks. After the seeds have germinated, the
watering should be reduced to less frequent, but longer, deeper
soakings to promote development of a healthy deeper root system.
Established, properly maintained zoysia turf will use far less
water than many other turf grass species.
Fertilization Of Zoysia Grass:
Approximately four weeks
after seeding apply a complete, balanced fertilizer to the newly
established turf area. For faster coverage during the
establishment year, a rate of 1 1/2 pounds of nitrogen per 1,000
square feet is recommended every month during the growing season.
After the first year, a light fertilizer application after spring
green-up and one in late summer should suffice to keep the zoysia
turf healthy.
Mowing Zoysia Grass
Start mowing the new
zoysia seedlings as soon as they reach 2 inches in height and mow
frequently to stimulate spread and reduce weed competition during
establishment. A turf height of 1-2 inches in full sun and 2-3
inches in shade will produce the best results. Zoysiagrass turf
can be mowed with any type of mower, but the blades must be kept
sharp to perform well on the tough zoysia leaves. After the first
year, mow as often as necessary to maintain a healthy turf and
good appearance. Zoysia grass is a slow growing turf species,
allowing for less frequent mowing when it is maintained correctly.
Pest And Weed Control With Zoysia Grass
Several weed
control products are labeled for zoysia grass turf during
establishment, as well as for later maintenance. Contact your
local extension office or turf chemical dealer for specific
recommendations in your area. Occasionally zoysia turf can suffer
minor damage from turf diseases such as Large Brown Patch (Rhizoctonia
fungus) or leaf rust, and from insect pests such as grubs, bill
bugs and mole crickets. Overall, well maintained zoysia turf is
resistant or tolerant to most turf insects and diseases. This
environmentally friendly turf species requires few chemicals for
good growth. Consult your local extension office or turf chemical
dealer for appropriate control recommendations if needed.
Winter Over Seeding Zoysia Grass
Both seeded and
vegetative Zoysia grass turf goes dormant during winter, turning a
golden brown color until warm temperatures return the following
spring. Winter overseeding with cool climate turf species is
generally NOT recommended on zoysia, especially on newly
established turf. Too heavy of a seed rate application or too
invasive of preparation method can severely damage any zoysia
stand. On mature healthy zoysia, if desired, a fall
overseeding application of perennial ryegrass seed such as
Champion can produce good results, but only seed the ryegrass at
half the normal seeding rate. Due to the density of zoysia turf,
the ryegrass seeds must be raked in well for good soil contact.
Mixing Or Inter Seeding Zoysia Grass
Seeded zoysia
performs well in a mixture with turf-type tall fescues, as long as
the turf manager maintains a primary fertilizer schedule in the
fall and early spring - do not fertilize in mid-summer for best
results.
