Just remove Pesticide application from all existing literature regarding maintaining a lawn and PRESTO you have a non herbicidal approach. Too bad the results are not the same.
If you learn nothing from NCAP’s Professional Tool Box, just remember 1 thing that worked for Portland Oregon (Know as the Hand Picking Lawn Weed Party Capital) .
Organic Lawn Care = Cut lawn 2 times a week and irrigate 750 acres of park land.
“The consistency of our cultural practices and turf management techniques has enabled Portland Parks and Recreation to manage, with the exception of a few acres in high profile ball fields, most of its general turf areas without any broadleaf herbicide use in the past 15 to 20 years,” asserts John Reed, Integrated Pest Management Program Coordinator and Botanic Specialist with Portland Parks and Recreation.3
Half of the 1,400 mowed acres that the department manages are groomed (279 sites, including 273 sports fields).
The irrigation department hired Horticulturist Linda Corbett to monitor
daily water use and annual cost, which totaled about $1.3 million last year.
The department irrigates more than 750 acres at 135 sites with
automatic irrigation systems, and 400 acres at 50 sites that are managed by central control.
NCAP has published a series of reports highlighting effective, non-herbicidal strategies used by city parks staff in the Northwest to control weeds in specific areas. NCAP interviewed 20 parks staff in eight cities throughout the Northwest (Eugene,Portland, Bend, Boise, San Francisco, Seattle, Corvallis, and Davis) to document these effective strategies.
