Dry weather
This is the time in the Adirondacks that everyone's lawn gets brown instead of green. I have been watering mine for day, it is still brown. I will have to get the fertilizer out and spread it and water it in since the weatherman is not predicting a lot of rain.
In the spring we mow the lawn every few days, and it is downhill from there. I mow mine less and less as the summer progresses and it looks less healthy at the same time.
Later this afternoon I will spread some Scott's and let it kill the weeds and grow the grass. Then I can go back to mowing it more often again.
