Poa annua is a common winter annual grassy weed in all turf types. It is easily seen in warm season turf during the winter because the turf is brownish in color while Poa annua is green. However, most people with fescue turf do not realize they have it until late spring when the Poa annua produces tan colored seed heads.
There are a couple products available that will control about 70% of Poa annua in Fescue. The product Fairway Green utilizes requires an application in November followed by a retreat thirty days later. You have to utilize the two applications to receive the 70% control.
It is important to remove and keep leaves off your turf. Severe damage will occur if leaves stay on your turf for extended periods. Damage can be quick and severe for Fescue lawns that had fall seeding or sod. It is best to blow leaves off of immature turf rather than raking.
Fescue seed is germinating slowly this fall due to the lack of regular natural rainfall and lower humidity. Regularly irrigated lawns are faring better but still a little slow. If you are not willing to or unable to water, be patient. It is not uncommon to have seed germinate and develop throughout the winter and very early spring. Usually the turf has developed enough to use pre-emergence safely in late February and early March.
Late September starts the Large Patch fungus season on Zoysia, Bermuda, Centipede and St. Augustine. Fairway Green is seeing more cases of this disease every year in our area. Large Patch Fungus is a damaging disease on Zoysia, Bermuda, Centipede and St. Augustine turf in the fall and early spring. This disease is similar to Brown Patch Fungus on Fescue. Large Patch Fungus needs to be controlled with two applications of fungicide in the fall and possibly two in the spring when ground temperatures are between 50 and 70 degrees. Damage occurs before you are aware you have it and is not visible until green-up in the spring. Preventative Fungicide in the fall and early spring is the only way to control this disease.
