Start watering IMMEDIATELY after the sod is laid. For the first 7 — 10 days, keep a close eye on your turf. Give it just enough water to keep it from drying out. After that, apply an inch of water every 7 — 10 days.
To measure an 1″ of water coming from a sprinkler, place a coffee can on the lawn in the midst of the sprinkler. A good watering once per week is usually better for your lawn than light daily watering. Once your lawn is established it is generally better to water in the morning hours.
By about the 10th day, allow the sod to dry out enough to mow it. Make sure your mower is in good mechanical condition with a sharp blade. Set your mower on the highest setting and mow the lawn very carefully. The frequency in which you will have to mow your lawn depends on weather conditions.
The following advice may be helpful: Mow the lawn before the clippings are longer than 1″. In the spring and fall, mowing may have to be done twice a week due to rapid growth. Mowing heights should be 2″ — 2-1/2″ in spring and fall and 2-1/2″ — 3″ during the summer months, this of course depends on the variety of grass..
Vigorously core cultivate the sod as soon as it has knitted to the soil (about 2 months). Core cultivation will remove cores of sod and soil and deposit them on the surface. Core cultivation should be done in the spring and fall every year.
Following initial fertilization, wait 6 weeks and fertilize again with a complete fertilizer. Repeat every 6 weeks for the remainder of the growing season. Next year, begin the cycle in late May or early June.
Weed and crabgrass control chemicals should not be used in the first year. The use of weed and crabgrass control chemicals should only be considered in extreme situations and then only as a spot treatment. Before applying any chemicals, read and follow all label instructions.
