How do you stimulate root growth with a sod lawn?

Question

Most of the sod lawns I see have only surface roots. A seeded lawn typically has a longer "green" season into the winter (in Colorado) because the root system is more mature.

Answer 1

nitrate soda -mix with water-follow instructions

Answer 2

deep watering for a long time

Answer 3

correct, the seeded lawns have better rooted system. sod is for those whom can not wait for the grass to grow from seed. seed your lawn, and then in a year or two, you will be sitting in it, enjoying, and watching those with sod, out there working on their lawn they could not wait for.  

Answer 4

spread some black dirt top soil out with a little seed and lots of water for the first month

Answer 5

Epsom salt either sprayed or distributed on the lawn with a fertilier spreader then slightly watered in
