Since a square mile is 640 acres, there are 30,229,760 acres in our state that will grow weeds if unattended. Approximately 12.6 million acres, or 40 percent of the state, are used for crop production and 60 percent, or 18.5 million acres, are used for timber production.
Weeds grow on every acre used for crop and timber production.
Weeds also grow in those areas not used for crop and timber production. Weeds can be found just about everywhere and all times of the year. There are many different types of weeds that invade lawns. A thick, dense turfgrass canopy is the best defense one can have against weed invasions. Diseases, insects, cold damage, inadequate sunlight, acid soils, poor drainage, fertilizer burn, poor fertility, poorly adapted turf type, poor mowing practices, or other factors can cause the turfgrass canopy to thin, creating areas for weeds to emerge.
