| Time of year to install |
Not recommended for Winter or Summer, possible in Spring, best in Fall for most areas. 1 / 2 / 3 |

Year-round installation, even on frozen ground if sod is available. 1 / 2 / 3 |
| Soil Preperation |
Same for all types of lawn installation: Deeply till soil, add necessary amendments and fertilizers, grade and level for smooth surface, remove all debris, lightly pack and moisten. 1 / 2 / 3 |

| Water Requirements |
Highest water needs- Bare soil will dry quickly. Water lightly for 3-4 weeks, keeping surface moist, begin to apply 1-inch of water per week after mowing. 1 / 2 / 3 |
Moderate to high water needs. Mulch will preserve some moisture. 1 / 2 / 3 |
Lowest water needs- Water at installation to a depth of 6-inches, then light waterings for next 2-3 weeks. Grass will shade soil and prevent drying. 1 / 2 / 3 |
| Seed Quality |
Extremely variable because of germination rates, weed and foreign matter content; unknown or unspecified varieties. Generally lower quality seed than used in cultivated sod production. 1 / 2 / 3 |

Typically highest available sod quality, certified, elite seed. May be certified to prove specific variety. Mixtures and blends used to suit area needs. 1 / 2 / 3 |
| Weed Control |
Multiple applications of chemicals usually required to combat competitive weed invasions until turf is well established. Mulch layer may reduce some problems. 1 / 2 / 3 |

Minimal, if any chemical control needed. 1 / 2 / 3 |
| Uniformity of Coverage |
Seeding varieties, rates, germination times, wash-outs (erosion), traffic, feeding birds and rodents can create spottiness. Mulch layer may reduce some problems. 1 / 2 / 3 |

99 to 100% uniformity with use of mature turfgrass sod. 1 / 2 / 3 |
| Runoff / Erosion |
Heavy rains or sloping areas will cause seed, chemicals and silt to wash onto sidewalks and into sewer systems. Little if any protection. Mulch should reduce erosion/runoff for several months. 1 / 2 / 3 |

Capable of handling heavy rains without erosion or damage. 1 / 2 / 3 |
| Visual Impact |
Rough texture and open soil. 1 / 2 / 3 |
Colored mulches act to camouflage soil appearance. 1 / 2 / 3 |
Immediate beauty of a 'complete' and mature landscape. 1 / 2 / 3 |
| Useability |
Low traffic use 2 to 4 months after seeding with faster germinating seed. Normal to high use only after first year. 1 / 2 / 3 |
Low traffic use 2 to 4 months after seeding with faster germinating seed. Normal to high use only after first year. 1 / 2 / 3 |
Low traffic immediately. Normal, high traffic levels within 2 to 3 weeks. 1 / 2 / 3 |
| Installation Costs |
Lowest cost. 1 / 2 / 3 |
Low to Mid-level cost. 1 / 2 / 3 |
Highest cost. 1 / 2 / 3 |
Cost vs. Value |
Higher management and maintenance costs, compounded by increased water and chemical applications, as well as delay of use, poor uniformity and visually unappealing are trade-offs for lower installation cost. 1 / 2 / 3 |
Higher management and maintenance costs, compounded by increased water and chemical applications, as well as delay of use, poor uniformity and visually unappealing are trade-offs for lower installation cost. 1 / 2 / 3 |
Installation costs offsey by added values of timing, useability, uniformity and visual appeal. Reduced maintenance, chemical and water costs. 1 / 2 / 3 |
