When is the latest time to plant grass seed? I'm planting fescue.?

Question

Essentially it's September Now. i live in Maryland (East Coast) I found patches of crab grass in my yard. I've sprayed the crab grass with weed killer and want to reseed. When is the latest I can reseed. Also I was told once it gets to cold my grass seed will die...

Answer 1

Fescue should do OK if you reseed now. There are many varieties of fescue. Check with your local garden center to see which variety best fits your situation.

Answer 2

I live just over the border in Virginia, near Potomac MD.

The crabgrass should die on its own - it's an annual and can't survive the winter. Run an aerator over the yard if you can. That'll help break up the clay soil we have in this area. Put down some gypsum too. Reseed now (it's a bit late, but you should be OK.)

In the spring, put down the Pre-emergent Crabgrass treatment. It stops the Crabgrass seeds from sprouting. It works for 120 days, supposedly. Actually, it stops ALL seeds from sprouting, so don't waste grass seed on the lawn after you've treated for crabgrass. The seeds will just rot.

Good luck - this was a bad year around here for crabgrass. Oy!

Answer 3

Rake up these spots. Get rid of any dead grass. Spread seed. Cover with straw. And water. This is the best time to sow grass. Warm days, cool nights. Just like spring. Grass has no problem growing in the spring. Don't mow until 2 weeks after you see 1st sprouts. water daily in early morn for 1st week. Don't fertilize until next late May- early June

Answer 4

I live in maryland also and you can reseed now itf the seed does not germinate it will in the spring as long as you do not put down crab grass preventer use a grass seed that is recommend for maryland. stay away from kentucky 31

Answer 5

Latest would be end of Sept. Best is End of Aug to MID SEPT.

You could try it now but chances are slim they would survive the winter months.

Answer 6

before the first hard frost
