Notes:

I’m trying to start a new lawn of Tifblair centipede. I applied Roundup and got everything killed off. I cored aerated the lawn, then planted the seed and applied fertilizer. For about 3 weeks now, this grass has been coming up over 80% of the yard. What is it?

    Anytime you improve soil conditions during the spring for a newly seeded or sodded lawn you’re improving conditions for weeds as well. Crabgrass is one of the first to take advantage of a fresh new growing enviroment. Fear not, with seeded centipede that’s ok! Plan to follow the three year plan with seeded centipede. It sleeps the first year, creeps the second year, and leaps the third year. Provided you have full sun your centipede will coexist just fine with the crabgrass and the annual weed grasses will help hold the soil during the grow in process. Mow weekly to reduce the weed grass canopy and feed your centipede lightly during April and August for the next three growing seasons. I would not apply any summer preEmergents until spring of the fourth year. Finally and, most importantly, the most used tool in your centipede kit will be patience.

    Crabgrass.
    It’s very common for annual seeds to come up after you’ve killed everything and exposed the soil to sunlight.
    Not sure there’s much you can do to stop the crabgrass from coming up if you are trying to grow new turf from seed.
