Breaking The One Third Rule

The One Third Rule:  Always mow your lawn before it's half again the normal mow height--so that you never mow off more than one third of the blade.

The mower is currently out on the north face, mowing away, and blatantly breaking the one third rule.  This time, it's more like the one half rule or even a touch more.  The grass is pushing six inches easily.

However, we're now on Day 12 without any appreciable rain (Day 9 with no rain at all), and temperatures holding in the mid seventies to mid eighties.  Mowing under those conditions would have invited a burn.

I've spent the last three evenings watering, so the ground is now moist and more normal rainfall is expected next week and the week following.

In this instance, I don't expect any serious side effects, although the grass' growth will slow temporarily while it recovers from the shock.  In late September, in tolerable weather, and on freshly irrigated soil, the shock should be minimal.
