Seed & Sod
Why Seed?
Advantages:
-
Larger selection of species available. Different mixes of species and blends of different cultivars are available for specific management practices, sun or shade, disease resistance and soil type.
-
Lower initial cost than sodding.
Disadvantages:
-
Timing of establishment is critical. Best time is in September. April is also a good time, but weed seeds germinate in greater numbers in Spring.
-
Longer time period to get a dense lawn.
-
May require reseeding due to poor germination in some areas or wash outs from heavy rain or irrigation.
-
Weeds can be a problem until lawn is fully established.
-
Initial watering is critical.
Why Sod?
Advantages:
-
"Instant Lawn"
-
May be walked on soon after planting.
-
Dust, mud and erosion are quickly reduced.
-
May be planted anytime during the growing season as long as adequate water is available.
-
Basically weed-free.
Disadvantages:
-
Higher initial cost than seeding.
-
Choice of species is limited.
-
Not produced in shaded environment.
-
Larger volume of water initially.
-
Sod may shrink and weeds may invade, especially if the sod is not properly installed. Do not stretch sod. Stagger seams similar to brick-laying.
-
Speed of rooting varies with season. Spring and Fall are optimal.
