• Do not apply any more nitrogen to lawns; it is time for them to get ready for winter.
• Days are getting shorter and cooler. Start cutting back on irrigation this month.
• Apply pre-emergent herbicides around Labor Day to control cool season weeds. Pre-emergent herbicides prevent weed seed from coming up.
• If your soil test report showed low potassium levels, apply a high potassium fertilizer such as 0-0-50 (2 lbs. per 1,000 sq. ft.) by mid September.
• If your lawn had problems with large patch in the spring, treat this fall.
