Bare spots on one side of lawn

I have a customers yard that is perfect on one side and very thin on the other side. I planned on aerating the lawn in a week. He has been putting down the Scott's Turf Care and his lawn is perfect on one whole side. The problem is the other side of the lawn is covered by big shady trees and does not get much sun. Is this fixable?

Hi birddog,
I don't have any experience with this, but do recall reading somewhere that maybe a different grass (shade area seed) can help to fill in the bare spots, as it seems that is the reason it may not be growing there. Also, have read something about how much the roots are not allowing the grass to grow there, and probably will not in the future. may want to come up with some creative bed designs for the house and propose them too, may get a lanscaping job out of it.
Hopefully some others with more experience can help you out here, but thought I would try!
Good luck with it.

If the side of the house you are dealing with is very shaded and has alot of trees you will be hard pressed to grow grass. The
area probably has very shallow topsoil because of the trees
roots. The pH is out of whack because of the trees. The pH is
generally acidic in shaded areas and the grass wants to be
growing in a neutral pH. Also the lack of sun will hinder the growth
of the grass.
The best thing to do is check the soil pH with a self tester kit or
you can take a sample to your local ad extension office for testing.
You will want to adjust the pH according to the soil test. Generally
that means adding lime. Then add topsoil to help the grass root
deeper. You can then seed with grass that is designed for shaded
areas (creeping red fescue, turf type tall fescue, perennial
ryegrass, etc.) Then keep watering during dry times because
the trees will win a fight for moisture over the grass (remember
70%-80% of all tree roots are within 8 inches of the surface, so
there is alot there to steal moisture from the grass. Finally you
may have to overseed every other year to keep grass growing.
Needless to say it is not easy growing grass under trees.
Good luck.

Sorry I forgot to mention this before. You may suggest that the
customer have a crown cleaning or crown thinning done to the
trees. This will allow more filtered light into the area and will
help the grass. That only works if the trees are not evergreen,
and you will want to do the things I mentioned above with this.
