The most important part of establishing a lawn is proper soil preparation. One of the main reasons for turfgrass failure is a poorly prepared site with inadequate soil characteristics. New construction in subdivisions requires removal of topsoil to allow contouring for adequate storm water drainage. Too often topsoil is not placed back around homes prior to lawn installation. Understanding the requirements of good seedbed preparation will help the long term success of a lawn.
Using good quality seed is also very important. Read the section on turfgrass selection to choose the correct type of grass for your application. Additionally, make sure to purchase seed that has a high germination rate (85% minimum) and contains minimal weed seed and “other crop seed.”
The best time to seed cool-season grasses in Idaho is late summer and fall for several reasons. Soil temperatures are optimum for seed germination, there is less competition from summer annual weeds, and the newly emerged grass seedlings will not be exposed to summer heat. It is possible to seed a lawn successfully in the spring, but extra care will be needed to help the seedlings along during the hot summer temperatures.
The establishment process includes: Site preparation/rough grading, seedbed preparation, seeding/sodding, post seeding/sodding care.
