    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.

    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.
