How do you get rid of brown spots in the grass?

Answer 1

First you have to know what's causing it: dog urine, grubs, disease, compaction, improper water application. If on a sprinkler system, set some straight side cans over the spots as well as the green area and run the sprinkler thru 1 or 2 cycles back to back. Measure the water. If lean where the brown spots are, look to clogged sprinkler head (no, you can't really tell by looking at them), improper overlap.

Then check the water actually penetrated by using a long shank screwdriver and shove it into the soil. It will penetrate easily where the water penetrated. If rock hard, soil needs work.

For grubs......not ideal time of year to check as they aren't "home" right now. The live in the soil from fall thru spring eating the grass roots. Sod webworms live in the thatch up top eating the grass. Chemicals or nematodes can control the grubs, dethatching the lawn will help with the sodwebworm.

Diseases can be caused by too much/too little water, too much/too little nitrogen. You need to take samples where the lawn borders the dead areas and get them to the Extension Service for diagnosis......fresh samples, not those left in the car for a few hours. Diseases are best controlled by correcting the underlying factor (water, nutrients) rather than relying solely on fungicides.

Answer 2

Depends what is causing the spots. Mealy worms, dog urine, watering at the wrong time of day.
