Not that we, or rather I, mowed our lawn often, at most ince every 3-4 weeks or so. This year, we decided to leave part of it to grow. The amount of insects in there was astounishing, so the patch stayed uncut between June and two weeks ago. The rain transfromed it ibto something less than pretty. Turned out the grass underneath is prettier than before. Next we gonna repeat the same thing with a different patch.
Did this for No-Mow-May. Left some patches unmowed for that month (we got a lot of rain in May this year). Lots of diversity in those patches. It was kind of hard to mow them in June - had to use the weed-eater first. Left a couple of the patches longer into July. Neighbor across the street almost came unhinged. Tried to explain that it was helping polinators... but it was a waste of breath.
Lucky us we don't have of those neighbors, and basically cannot get them. No HOAs or similar shenenigans were we live, even the city leaves large patches in parks unmowed until automn in some places.
