How High to Mow Your Lawn for the Final Cut in the Fall

Lawn mower cutting grass

Set your lawn mower a notch lower for the final lawn mowing in the fall.

What height should I mow my lawn for my final cut of fall? -John

During summer, lawns should be mowed at the highest setting, since you need the extra grass height to hold moisture and keep the soil cool. However, once your grass stops growing for the year, it’s a good idea to give it one last cutting at a lower height.

If left long during the winter, that extra top growth will bend under the weight of snow and rain, trapping cool moisture that quickly breeds winter fungal diseases. And, a lower mowing height will be more effective in mulching up fallen leaves.

For the last mowing or two of fall, simply lower your blades one notch, or set the blades at the lowest mowing height recommended for your grass type.

In spring, leave your mower blades at the lower setting for the first couple of mowings, then return the blades to the higher setting for the summer.

    On top of the first comment I made if you cut the grass at the proper lane and you have your grass trained properly you will never ever need a catcher to catch your grass no matter how high that Grass Grows All You Need is a mulch kit in the grass will fall in between, the grass will eat everything. By the time I finish cutting my grass I can go walk on it with a fresh pair of white Nikes and not get one staying in it that’s how good I am.

    Governor Rick Scott limo pulled out 10 minutes before I cut the grass he was holding fundraisers at $10,000 a plate and was told that nobody ever and handle that long the way me and my crew have.

    Always had to fall tototill , fall overseed. Big pain in autum. 2 years ago after lawn destroyed by road project I tried drought dry weather tall fescue we don’t water much. Then actually read citing info , went from short citing to 3.5 inch on my Deere rider the first comment came from the short cut taking letter carrier ,then several others on the cushion lawn plus no drought damage after 40 years now retired a showpiece lawn . With your info its Nov. & I’m lowering the mow deck.

    I agree with most of your suggestions , my only exception is to remove the spark plug , pour or squirt light coalting of oil in the plug hole , replace the plug and crank the cord three to four times to lubricant the system .

    My lawn has a very sandy base not a good rooting system. Should I still cut it short for winter?

    This is a great piece considering that most homeowners do not place much importance on the height of their grass cutting in correspondence to the changing seasons. Thank you so much for the great information!

    Hi! I live in Ohio. My first 2 mowings have been set next to the highest. Is that to high? Should I drop it down one & mow at that length until May? My yard looks good. My husband thinks its to long. I have been told to keep it close to high in the spring & here on out. Please let me know, its confusing on what to do. Thank you. Sharon
