Converting Cool & Warm Season Lawns To Zoysia
Instructions on how to convert an existing turf grass to a
Zenith or Compadre lawn with seeds.
Seeding into existing lawns without first
killing them is not generally recommended as it is hard for the
little slower growing Zoysia seedlings to survive competition
from your established grass. Use plugs for lawns that will
not be killed.
These instructions also apply to establishment
in warm season grasses, though often a warm season grass may
be harder to kill with a glyphosphate such as Roundup. You
may end up with a mixed lawn if the lawn is not totally killed
through multiple treatments and patience! Tilling the soil
such as was done in our Pictorial
guide is the best planting method (see
www.grassing.com )... but
many people simply don't or can't go to that level of preparation.
seed Zenith if a pre-emerge herbicide has been applied
within the previous 60 days
Not Over Water
fertility as suggested once turf cover is accomplished
Do not use herbicides until after about 12 weeks of growth has occurred.
|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.

Apply Roundup® at label recommended
rates to kill existing plant cover. IF you do NOT want to
kill your existing lawn.. then you should consider planting
plugs and NOT seeds.
Apply a second application if needed to completely kill existing
Just prior to seeding your zoysia (at
time), scalp the lawn and
remove debris and clippings.
Aerate to bring soil to the surface.
A hollow tine aerator is best (core aerator), but if not
available a spike aerator will suffice. Vertical mowers can be
used to help make little slits in the soil that are good for seeds
making proper soil contact.
Apply lime and fertilizer as needed to
adjust pH to 6.0-7.5 and lime as needed. Obtain a soil test to
Plant at 45 to 90 lbs per acre (1-2 lbs
per 1000 sq. ft. - 50 to 100 kg/H).
Using a drop or broadcast spreader,
spread 1/2 of your seed one direction and 1/2 in another to provide
good coverage. (First broadcast East-West, then North-South).
A slit seeder can be used for more precise planting. These can
be rented from some rental companies.
Roll after seeding if possible to
smooth area and insure good seed/soil contact.
Do NOT cover seeds more than 1/4 inch with
soil. Light is a key factor in germination and ideal
planting depth is 1/8 inch. The seeds will NOT germinate
broadcast on top of the soil.
Irrigate to keep soil moist (2 to 3
times daily for the first 14 to 21 days or until seedlings are
After seedlings have emerged, irrigate
to keep good moisture in the soil to a depth of 1 inch. DO NOT
OVER WATER! Too much water can cause seedling diseases and
kill your new grass.
Four (4), Eight (8) & twelve (12) weeks after planting
apply 400 lbs per acre (about 9 lbs per 1000 sq. ft) of a 10-10-10
or 8-8-8 fertilizer.
Avoid application of fertilizers high in
nitrogen in the late fall. For established turf (2 years and
older), apply the equivalent of 1 pound of nitrogen every 2 to 4
growing months using a balanced fertilizer. You should
determine the correct fertilizer based on a soil test. Contact
agent for help on this.

MOWING ZOYSIA GRASS
Mow lower areas if possible with a
reel mower. The grass can be mowed with a rotary mower at
higher levels. Begin mowing at 2 inches (50mm) height as soon
as grass or weeds can be cut. If using a rotary mower you may
want to continue cutting at 2 inch height. Reel mowers can be
gradually reduced to 3/4 to 1/2 inch over time.
Zoysia generally requires 10 fewer
mowings than the average Bermuda grass lawn.
Always use "SHARP" mower blades for
best results. Zoysia is a tough grass that requires a clean
cut to look good. Only sharp blades will give you this look.
DO NOT PLANT ZOYSIA SEED if a
pre-emerge herbicide has been applied with the previous 60 days.
Do not use herbicides until after about 12 weeks of growth has
