The best way to keep the weeds out of the lawn is to have a higher
mowing hight, 2 1/2 to 3 inches is best and a good fertilizer program.
Fertilizing in the mid spring and again in the early fall and you should
have nice looking turf.

Good luck.

The higher you cut the grass the fewer grass plants you will have per
square foot. Long term this may not help to reduce weeds as a thicker
lawn
will do a better job of preventing infestation.

This statement maybe true...if one was to mow a 12 inches 80P
If a person was to keep the grass length to 2 to 4 inches, mowed
regularly (weekly) and fertilize twice a year, many of the more common
lawn issues will be gone. This by no means implies that the lawn will be a
weed free haven but it's a situation that can be managed with acceptable
results (for most people).

The explanation given by our local cooperative extension is logical: If you
hack the average lawn down to putting green level, you're removing a
significant amount of leaf area, without which the grass cannot
photosynthesize enough. Sort of like hacking 75% of the leaves off your
dogwood every 10 days.
