Newly seeded lawn: When to cut?
I reseeded our entire yard (fescue, Georgia) about 3-4 weeks ago after doing extensive prep work. But we had a BIG rain shortly after the seed went down and I lost a bunch of the seed due to washout,....however about half the yard ended up taking.
The result was really patchy germination. After getting great advice on this forum, I bought some more seed, froze it, prepped the areas needed, thawed the seed and reseeded this past Thursday. I've had great luck bc we got a nice misty rain most of the weekend. Haven't seen germination of the new seed yet, but am very optimistic that we will soon bc of the misting rain and bc the freezing is supposed to shorten the germination period to around 5 days.
HERE'S THE QUESTION: The first round of seed is now about 1.5-2 inches tall. I think fescue is supposed to be cut at about 3 inches. Is this going to be bad for the second round of seed I threw down? How would you all suggest handling cutting for the first time? How tall is too tall to wait? Assuming the second round of seed is germinating somewhat by the time the other grass is 3 inches tall, will it hold in place or be sucked up by a mower?
I have a mulching/bagging push behind mower that can be set from 1 to 5. Also I have a good string trimmer. Maybe this would be the way to go because I would have greater control on what gets cut, how low, and I wouldn't have to push a mower on the still germinating lawn.
Any thoughts or questions are most welcome.
