A U.S. Forest Service grant is again available to assist non-industrial private landowners with the cost of controlling cogongrass. Applications will be accepted starting October 15, 2015. The program reimburses landowners for 50% of the cost for two consecutive years with a maximum reimbursement of $10,000 for each year.

Cogongrass is one of the worst invasive plant species in Northwest Florida as it marches through natural areas and literally chokes out our desirable native vegetation as it goes. The underground rhizomes continually expand patches of the grass in every direction and its prolific seed production carries infestations to new areas.

There are several ways to accurately identify cogongrass. The leaf blades are flat with serrated edges and tend to be yellowish-green in color. The midrib which runs lengthwise up each leaf blade is white and is distinctly off-center. The seed head which arises in the spring is a fluffy white plume. Since it spreads through rhizomes, cogongrass is often seen in expanding circular patches.
