SPRING and SUMMER Guidelines
Keep it green:
Upon installing, water
immediately. For two weeks after, water 15 minutes twice every
midday, and 20 min. every evening. Grass is established when it can't
be pulled up from the ground. Then, continue to water 20 min. a day.
Setting happens:
When new structures
are built on idle land many ground disturbances must occur, such as the
burying of sewer, electric, and sprinkler lines. Ample sod watering
provokes the land to settle around the disturbances. Lawn settling
is not the fault of the developer, builder or the sod installer; it is
a common consequence of modern construction.
Top Dressing:
The only way to
regain a level yard after settling: 1) Wait three weeks after grass
establishment 2) Buy some sand 3) Using a shovel, cast the
sand into the depressed areas of the yard, and 4) Use the back side
of a rake to level the piles. The grass will grow through the sand within
six to eight weeks, depending on the amount of sand.
Fertilizing:
Our sod is fertilized
in the field every month of the growing season. Upon establishment,
fertilizer maintains grass health and promotes root depth. Use a
high nitrogen mix or "10-20-10" equivalent every month of the growing season.
Water is critical during the post-fertilization time; usually 30 minutes
a day for a week should produce a lush, green lawn.
FALL and WINTER Guidelines
Dormant, Not Invincible:
Sod is a perishable
product even when installed in dormancy. It must be cared for properly
to survive the winter. For the first three months, all new dormant
sod requires a deep watering at least two times per week. After this
time period, water deeply one time every week until the grass turns green.
Freeze Warning:
If a deep freeze
is forecasted, sod must be watered prior to and wet at the time of the
freeze. Some areas of the yard may die if proper moisture is lacking.
Weed Overkill:
Do not spray dormant
sod for weeds or pre-emerge. The tender root hairs trying to attach
will not withstand herbicide, resulting in dead patches.
Fertilize:
About mid-April, begin
regularly applying a high-nitrogen fertilizer or "10-20-10" equivalent
every month to achieve a healthy, deep green yard. The last application
should be mid-September, ensuring the root durability needed to make it
through the winter.
These guidelines will assure that
there will be no confusion in the care of your new sod, and keep your investment
looking healthy and green year after year. For further information about
