Establishment and Maintenance Recommendations
Floratam is sold in one-foot by two feet blocks; four ½ of these blocks
equal one square yard (approximate figure due to shrinkage of blocks after harvesting),
and weighs about 60 pounds to a yard.
When the Floratam arrives at the designated planting area, it should be spread out and watered if it is not going to be planted the same day of purchase. It is best to put the sod in a cool place; preferably on polyethylene sheeting. Water the sod daily until planted. If watered in this manner, it can be kept for months.
Planting Information
There are two methods used in planting Floratam sod:
1) Planting sod (grass with dirt on it) by cutting the sod into three-or-four
inch plugs; and
2) Planting the sections of sod side-by-side or solid sodding
How to Figure the Amount of Yards of Floratam Required for Planting
The following table gives the recommended distance for planting plugs and the amount of Floratam needed to plant a 1000 square foot area.

* There are 144 three-inch plugs in one sq. yard of Floratam.
** There are 81 four-inch plugs in one sq. yard of Floratam.
First, decide on the planting method you are going to use; the distance used for planting; and determine how many square feet of area you need to cover. Then, using the table above, figure the total amount of square yards of Floratam required.
Example: If you are going to use three-inch plugs and space
the centers 12-inch apart, and you have 2000 sq. feet of area to plant -- you
would multiply seven yards (which is the amount required for 1000 sq. feet)
by two to determine that 14 square yards of Floratam will be required to plant
the area.
Planting Instructions
Plugging - - - Grass should be cut in three or four-inch plugs. Plugs should be planted so that the grass appears just above the surface of the ground. Pack the soil firmly around each plug. Water should be applied to a planted area immediately after planting. Additional irrigation is advised every two-to-four days thereafter until the plugs are established. Plugging is the best method used in planting Floratam. Plugs have a better chance of survival in extreme weather. They also have a more rapid rate of coverage because grass runners will grow out from every direction from the plug.
Plugs can also be used to spot plant a lawn infested with St. Augustine Decline. Plant these plugs about two-feet apart throughout your lawn. Clean a spot about six-inches in diameter, and plant the plug in the center of this clean area. Repeat this procedure whenever you plant a plug.
After planting Floratam there is sometimes an infestation of
foreign grasses. These should be weeded out by hand if you have trees or shrubbery.
After the Floratam has a solid mat, you will not have any problems with foreign
grasses except for Dallis grass and this can be chopped out with a hoe or sprayed
individually with a glyphosate or M.S.M.A., making sure you spray only the Dallis
grass. This spot should be quickly covered by the Floratam in your lawn. If
you have not fertilized your soil while working it up, then fertilize your grass
about two weeks after planting with a complete slow-release fertilizer such
as 19-5-9 using eight pounds per 1000 square feet and follow with water irrigation.
This fertilization program can be used every six weeks to two months thereafter
until the planted area is established.
Mowing
This grass is coarser in texture when growing; however, when it has completely covered a lawn, these features are diminished. This is due to the fact that as the grass gains thicker coverage, the joints grow smaller in length. The leaves which might appear should be mowed. Mowing height should not be over one and one-half inch and should be started at one-half inch as the grass is about three-fourths covered. When the lawn is completely covered, gradually raise the mowing height and keep it at the same range that appears to be the best is between one to one-and-a-half inches; however, if you do not water in dry weather, mow the grass at a two inch length or as high as your lawn mower will mow.
