Lawn problems

I'm in the Los Angeles area, i have marathon sod in my lawn. of for the past few years during the warm summer months i have problems with the lawn developing large spots of brown and yellow spots.  Its not from dogs or other animals. I have tried aerating and fertilizing regularly and i do seem to have problems with hard compact soil.  i have notice a lot of water run off when i water the lawn. 


I'm a bit frustrated because during other times of the year and when the heat appears to subside by around September, the lawn just seems to green up and rejuvenate.  Can someone tell me what i may be doing wrong? 


Appreciate the suggestions and recommendations.

Hello sj62. Ken here in the Chicago area. Welcome to the Community.

I checked out Marathon Sod online and found out it contains varieties

of tall fescue grass. Tall fescue is a cool season grass. It does best in the

northern tier states year- round and fall-winter-spring where you live. A

warm season grass like Bermuda or St. Augustine would eliminate the

brown/yellow problem during the warmer months, but would go dormant (brown)

in the winter and require over seeding with annual ryegrass to stay green. Your

Marathon sod is your best bet because it won’t go brown in the winter.

The problem is soil compaction combined with a cool season grass. Go rent an aerator

from a tool rental at your local Home Depot. It will take out a plug of soil which will allow

the soil to expand and let the water go deeper into the soil. This will solve your

runoff problem and allow more water for uptake by the grass.

I would also test your soil for ph. Too high and too low will cause problems with

nutrient uptake. Also make sure that you are watering in the morning so the grass has moisture

during the heat of the day. I hope this helps. Good luck and take care.
