We are on 6 ac. & only mow right around the house & the driveways (which are grass). The rest we don't mow until usually late Sept./Oct. Right now there is a veritable sea of white when you look out at the unmown portions. Native something in the aster family, they have blooms only about 1/2" across but are prolific. I have also wildsown rudbeckia, phlox, bee balm, flax, Mexican hat, clasping coneflower, several kinds of coreopsis, gallardia, standing cypress, chickory, lupine and I don't even remember everything else but they are all out there interspersed with the white which has center stage at the moment. I have sown clover but it doesn't seem to want to do much.
No poisons used here.
Our neighbors in the back have 16 ac. but it's mostly cow pasture for their cows. They do have 2 hives of bees. She told me year before last that they were so glad we let the wildflowers grow & don't mow because their bees produced a bumper crop of honey. The bees are particularly fond of one of our bird baths especially when high summer hits & they are looking for water during their foraging missions.
