Lawn???

We do mow some of the ground cover in our yard, but very little of it is lawn grass. It's mostly forest floor without a forest. But (a) very little of it is green yet, and none is long enough to mow, and (b) we practise "no-mow May".
No-mow May is a program to protect pollinators. April doesn't count, because nothing is growing yet. By May, some lawns are getting high enough to cut, but there are very few flowering plants. Pollinators, mostly bees, have very little to eat. What there is is dandelions. Lots and lots of dandelions. The program asks people not to mow in May in order to protect the dandelions, to protect the bees. By June, enough other flowers are out that it is okay to mow dandelions.
They also ask us to leave the leaf litter from last fall until after that first mowing in June, to provide habitat for a lot of beneficial insects that haven't woken up from hibernation yet.
When it is time to mow, I do it myself.
