Best practices:

Lawn care:

Mow High, Let Clippings Lie.

To build turf up I'd easily recommend using Milorganite fertilization 4 times a year as directed. 

I reserve the use of chemical treatment for weeds only for stubborn invasive species commonly seen here on Long Island like yellow nutsedge (C. esculentus).

All other weeds can be dug out by hand as we've been taught correctly by our professors.
