Sod is perishable and needs to be installed within 36 hours of cutting.



1.       If there are weeds or other vegetation, remove them. Rototill area to and least a 3” depth then add soil. If you need to add fill dirt to bring up to grade, rototill then add soil. Do not spread top soil on top of hard ground. Layers of soil will remain for years.

2.       Compact or firm the ground by rolling.

3.       Lightly rake soil before laying sod.

4.       If soil is hot or dry, lightly water soil before laying sod.

5.       It is very important to apply a high phosphorous fertilizer for proper root development. It is better to do this before laying sod. Three weeks after sod installation apply a well-balanced high nitrogen lawn fertilizer. We have liquid fertilizer which is easier to apply evenly. Regular fertilizer applications are absolutely essential to maintain your lawn and keep weeds and undesirable greases from invading your lawn.


1.       Lay sod starting at a straight wall or drive.

2.       Fit rolls together, do not overlap or stretch.

3.       Begin watering lightly as soon as you have a small section laid. This is very important when the weather is hot; do not wait until all sod is laid.


1.       Water entire area with a ½ inch of water. To determine how much your sprinkler puts out, lay a pan on the turf to see how long it takes to reach a ½ inch. Never apply more than ¾ inch of water to your lawn at one time.

2.       Roll the watered “soft” sod with a roller/tamp to get air from under rolls and stick joints together.

3.       It is important to realize that new sod requires water often. Keep sod wet until the roots are established in the soil. When hot, water a minimum of twice per day, about ¼” each time. Continue twice per day for 2 weeks, then once per day for another 2 weeks.

4.       After grass is established, it needs to be watered regularly. Twice per week is recommended, about ½” each time. In hot weather, grass requires about 1” per week. Grass sloped to south, west, or up against brick/concrete walls will require extra water. When the temperature is below freezing it isn’t necessary to water. When the weather is warm, even in fall/winter, it’s helpful to water if the sod was installed in late summer or fall.


1.       Mow whenever it needs it. Allow ground to dry slightly, so mowing won’t tear up the sod. At 1 1/2 “-2 ½” in hot weather, never less then at 2”. In early spring and late fall, mow very short and catch clippings.

2.       When mowing, never remove more than 1/3” of the leaf. This causes severe stress and damage to the root system and may last months. If grass is long, set your mower high and keep the blade very sharp. If you cut less than 1 ½” remove them.


Consistent fertilizing is essential. It is stressful for grass to be fertilized, then go long periods without, then resume. Important times to fertilize are in the fall (late September or October). Four applications per year are recommended. Gauge the need for fertilizer by the look of the grass. By the time the grass appears a pale green color, it has already been stressed and it will take time for the nutrients to be absorbed.
