SOD INSTALLATION
What is sod?
Also known as turf, sod is the upper layer of pre-grown grass, including the soil and roots, harvested into rolls that is ready to layout over prepared ground to establish a new lawn. Sod is more expensive than grass seed, so it's not for everyone. But there are some circumstances where sod is the most sensible way to plant a new lawn.
Sod can be used on commercial and residential properties not only to start a new lawn but also to repair bare patches and prevent erosion on slopes. In addition, it is also effective in increasing cooling, improving air and water quality, and assisting in flood prevention by draining water. Sod also highly effective for erosion control on hillsides and sloped areas to reduce runoff velocity, the potential for sheet erosion and rill formation.
The best grass types for Southern Ontario?
The different types of grass are used for sod installations in Southern Ontario are cool-season grasses because they stand up to the punishing cold of winter. They're in danger of going dormant when summer temperatures reach above 90 degrees Fahrenheit. The two main types are:
-
Kentucky Bluegrass (Poa pratensis) can be grown in zones 3 to 7. Valued for its bluish-green color, it has distinct pros and cons. Benefits include its tolerance for foot traffic, its soft texture (great for bare feet), and its ability to bounce back from stress. But it's intolerant of heat, drought, and shade.
-
Tall Fescue (Festuca spp.) can be grown in zones 3 to 8 and has a clumping habit. It looks different from most other lawn grasses: It has wide, dark green wide blades that are coarse to the touch. It tolerates foot traffic and drought and doesn't produce much thatch, but it doesn't blend as well with other turf types in a lawn as most grasses do.
