Where im at, if I didn't mow until June my lawn would be three feet tall and i'd have several tickets. Still, I don't mow until may, and then just the front for another few weeks.

You want biodiversity? Don't weed, don't spread any pesticides or growth chemicals, and don't let the natural grass go so long it chokes out the other plants. And the real key, is don't do any of those things for years. From the street, my yard looks like a yard. It's a different color than the neighbors, but it's still green. Up close, it's a salad. More violets, Moss, clover, flowers, wild lettuce, and a hundred things I can't identify than grass. Its full of bees, caterpillars, beetles, butterflies, and stick bugs.

I got my neighbor on board, and we're single handedly keeping fireflies alive in the city. I started seeing bugs I haven't seen since I was a kid.

As an added bonus, since it's a smaller proportion grass, I don't have to mow half as often to keep it looking 'nice'.

I'm not an ecologist, but I feel like it's a solid step in the right direction.

I read a report that suggests longer grass encourages small mammals to set up breeding areas and that mow in June kills them. Animals like shrews, hedgehogs, harvest mice, they're all being mowed up.

By mowing normally and leaving the hedgerows intact we allow animals to choose safe nesting spots.

Grass yards are so ugly i dont get how people like them (Yes i realize for high traffic areas its somewhat needed)

My family's yard has diffrent sections of field, and they get so pretty the longer you let them do their thing! Id rather have a feild of flowers then some ugly grass that never gets used.

Kill your lawn, use ground cover

Uhh. The best is to remove grass and replace it with nitrogen fixers like clover, then plant trees..
