Mowing

I am cutting my blue grass lawn at 2 3/4" right now. As I reach the final mowings of the year should I lower the height?
If so, to what height!

Yes. remember the rule of 1/3s. Don't cut more then a third off at a time. I would bring the last cut of the year to 2" maybe 2.25".

Is this true for a newly seeded lawn (Mid-Sept) as well? I renovated my front lawn (about 3,000 sq ft) and am not sure what height I should keep it at for the winter. Right now the grass ranges from about 3 inches or so to 5 or more. I seeded twice because the first seeding had some patches, so the grass is at different stages of growth I guess. Basically, is this cut rule the same for new grass?

Also, should I apply winter fertilizer, or would it be too soon to fertilize a new lawn? I applied starter fertilizer when I seeded. It is a mix of KBG, Fescue, and PR if that matters for either questions.

Yes, the cut rule is the same for new grass. If it were me, I would cut your lawn now at roughly 3.5". Then wait a week or so depending on how much it has grown, and come down to 2.75" or 3", etc.

Your KBG could use fertilizer now, in addition to the winter fertilizer. Wait until you get more into winter (yes, OK, forget about the storm you had the other day) :), to apply winter fertilizer. You should apply the last batch of fert. a couple weeks before the grass stops growing for the year - don't forget to water it in.

Thanks for the response... I will do that. KGB gets special fertilizer I guess? What would that be called?

RE: Mowing

KBG get's 'extra' fertilizer (nitrogen). For the most part your tall fescue shouldn't really mind the extra. Typically KBG needs an extra 1 or 2 applications of nitrogen then TTTF (turf type tall fescue) does. For you, you will want to find a happy medium. Go ahead and apply probably around between .75 lbs of N per 1,000 sq. ft. and 1 lb. per 1,000.
