Is it too late in the year to install new turf?
No, it is not too late. In fact fall is one of the best times to install turf grass sod. We live and grow in a cool season turf zone. This includes fescue and fescue blends as well as Kentucky, Texas and bluegrass blends. Cool season grasses thrive in the cooler temperatures of fall.
Ground temperatures in fall are more conducive to root growth and establishment. Though outside air temperatures may be falling ground temperatures stay consistent which is good for new turf root establishment. When air temperatures are consistently 75 degrees ground temperatures will be around 65 degrees. A good rule of thumb is a ten degree difference from air to ground temperatures. Most active root growth is when ground temperatures are between 50 and 65 degrees. When soil temperatures are below 50 and above 65 root growth slows with higher soil temperatures root growth can stop.
In summer months when air temperatures are consistently over 90 degrees soil temperatures can be over 80. In high soil heat root growth slows or stops. High soil temperatures can be damaging to root systems.
Now, near end of September through November is a great time to install new turf grass.
