Should I mow the lawn lower being that it is now getting into the 40's during the late evenings? I live on Long Island, NY.

i have heard this. Its supposed to help with stuff like snow mold. I did experiment with 1 lawn last year. left it at normal and got snow mold. other lawns cut shorter and no mold. so maybe we should. Hope others will help us on this.

The reason to cut short like 2 3/4 inch is to keep the lawn from getting long and laying over. the laying over causes fungus. So yea cut short the last cut it wont hurt and probably will help.

Weve always cut it medium/long this time of year to promote deeper root growth. Roots stay active during winter months. feed them with potasium as well this time of year

In the south they still grow, but they wont grow under 30+ inches of snow, which is what we are going to get this winter in 1 storm. A man can dream cant he. In the north do they stay active, I always thought the whole plant goes dormant. If the ground is frozen where the roots are, how can they absorb water.

I believe you are right, 33 degrees is the lower limit of root growth for cool season grasses as I understand.

this debate has been going on for some time, I feel that you should leave it at a medium height

When you leave it high yes it can lay over and cause mold, but when you cut it short you eliminate the surface area of the blade more, which can decrease the area where photosythesis takes place, in turn can decrease the amount of carbohydrates being produced, which hurts the grass more in regards to the amount of energy being stored for winter.

We cut it shorter before leaf season only to make blowing leaves easier. Plus, I want to be picking up just leaves (I don't need grass clippings as well) in our Trac Vac collection barrels.

Yes we cut around 2.5 inches this time of year.

we also cut ours short in the fall because some of our customers can not afford a fall clean-up. Shorter the grass the better the leaves blow off.

I'm still cutting at 3.5-4 inches. I usually wait 'til what I believe to be the final cut of the season and drop it down to 3 inches.

I usually mow at 3 1/2 - 3 3/4".. I dropped the deck 1/4" this week for all accounts and will drop another 1/4" every week until the end of the season.. So most will be 2 1/2-2 3/4 when I park the mowers..

When I took my classes at Purdue, they said to cut it normal. They told us if you shorten it more, you get into the crown and harm the grass.

You shouldn't harm the grass if you lower it in stages.. Dropping if from 3 1/2" to 2" will put a bit of stress on it, but it shouldn't do much this time of year. Doing it in the summer would be a huge noticeable difference, but now, with all the rain we've had.. It should be fine..

Usually go 2.5 in the fall..2 3/4-3 in spring and late summer, and 3-3 1/2 in the hot summer months.

We haven't had any rain in 4 weeks. Nothing against anyone elses advice, but I'm gonna trust the Purdue guys at the turfgrass research center. I figure they got their job for a reason.

Its a good idea just before fall clean ups for us its another month before we start them so for now I plan on keeping the normal heights I want to get as many cuts in as I can before the season ends. Every week of cutting is another 3-4k in the war chest for winter for us so I say keep cutting till fall is really here.

All shorter cuts should be worked down slowly if possible for best turf health and results. You don't want to be cutting into the crowns. So if you wish, work them down a little as slowing growth allows for.

I always cut a bit shorter after October 1. In Ohio its getting cool enough that there is no more worry of heat stress, plus it makes blowing or bagging leaves much easier. The customers seem to like it shorter also.

Thanks,,, Cliff

WE cut it lower in the fall also to prevent layover & mold.
Yes it does make leaf blowing easier too.

Right now we rare down to 3.0 from 3.5 and 3.25. ON some we will go down to 2.75 but thats as low as we'll go. Most will stay at 3.0. I have rarely seen snow mold damage even in a tough winter. Rather, if theres alot of snowcover most of the winter, the voles do more damage than the snow mold.
