Mowing Heights and Plant Health

With winter on the horizon I guess, I wanted to talk about mowing heights in relation to winterkill and plant health .The  2014,15 winters was the worst  we have seen in a while and we had some winterkill as everyone saw. The biggest factor the temperatures, we cannot control so we have to deal with what we can control like mowing heights. Bermuda grass can tolerate low mowing heights but the more plant up top means  more roots  and rhizomes on the bottom which is true with any plant. My point is we raise mowing heights through the growing season to get the plant as healthy as we can going into winter .This  enables the plant to store more energy in its roots and stuff to combat low temperatures drought ,traffic , snow and ice. Just a little information on that factor and hopefully this winter won't be as bad as the last few.
