I never got around to doing a final mow in the fall, and I'm wondering if
there would be any benefit or if it would hurt my lawn if I did it now.
It is currently a couple degrees below freezing although last night it went
to 10 below (Celsius).
Unlikely to hurt anything, although not all mowers do well in the cold (most are
optimized for warm-weather operation, which makes sense).
I just did my final mow / leaf mulch last weekend (I don't like to rake leaves,
so I run the mulching mower over them a couple of passes). We were having a
warm spell, 'tho -- temps around 5 Celcius.
I don't know about the first sentence but I've walked on many a frozen
lawns (without scuffing my feet) and never saw damage to them over the
years. I believe the reason is that as long as the root system is
well nourished and undamaged, what happens above ground is not that
important. Our frost depth was well below the roots and our lawn
never seemed to suffer from being frozen.
Walking on frozen grass will not harm the HEALTH of the grass, but it can
(temporarily) damage the APPEARANCE of the grass. When stepped on, the ice
crystals in the leaves puncture the epidermal cells, potentially leaving
I'm no authority but that seems to sound possible but in my case,
never noticed this to happen. Ofcourse this was just in the case of
my lawn so I won't say it can't happen to others. My guess is the
general health of the lawn, type of grass, soil type, etc.. probably
have a lot to do with what a frozen lawn can withstand. I never had a
need nor wanted to cut my frozen lawn. I bet if I did, my neighbors
would have thought I was crazy. I don't know if it would hurt to cut
the frozen lawn but I don't think I'd do it since not doing it seems
to do no harm to the lawn from my experience.
