Grass on new lawn
I'm finishing up building a brand new home. In mid September, we limed, ferterlized, and seeded our 3 acre yard with turf style fescue. We've had a very good stand and the grass has grown in thick and is very tall now...

Question: When is the correct time to give it its first cut? A relative said that he heard that it is best to wait on a new lawn until the grass has had time to head out....then cut it. he siad that this causes more seed to be spread.

You want to cut it as soon as it reaches normal mowing height.
Cut it when it is a little dry and probably bag it since its kinda tall.

Taller grass will tend to lay over on the grass next to it and slow strong root development. Normal height forces the roots to grow deeper/stronger.

I used to think it was good to let it grow long and seed out also. :no:

Probably time for one more load of fert also.

If it is at the point of dying for the winter, depending on your location I would just leave it. I always leave my grass long come late fall to provide ground cover and protect the roots.

Either way works though. It is more preference than anything else.

"wait on a new lawn until the grass has had time to head out...."

Frankly, I have never seen turf-type fescue come to seed heads. Maybe if one examined veeeery closely, but not such as common bermuda, crabgrass, etc.

I usually let it grow just a little higher than normal cutting height before the first cutting. The vigorous growth creates a demand for more roots (the water and food intake system), at least in my understanding. So, the extra top growth is for root developement, not for seed production. IF, the seedlings come up fine and then are deprived due to drought, etc, they will suffer if left too high. Mowing then will reduce the stress of that need. Think of working outside on a hot day and run out of water to drink. Most people will slow down and not work so hard.

"this causes more seed to be spread."

If the seed is sown at the proper rate, comes up adequately (as you posted), and is managed properly, producing seed is not a factor in the picture. In fact, seed that is sown too heavily will cause the grass seedlings to dwindle somewhat like any other supply and demand of too many (people, plants, etc,) and not enough water and food. I tend to think that a lawn seeded at the proper rate would therefore suffer if excess seeds were produced and allowed to germinate.

Thanks for the responses...I'm in North Georgia and the fescue is still really green!
