Chiggers! Yep, we have chiggers--in fact, I am scratching bites from six of them today.
Since I no longer drive, I have wildflowers planted in parts of the driveway. The front yard is mostly perennials. Left enough grass to provide access, and for aesthetic reasons (I like the visual break). Back yard is mostly St. Augustine, which I hate, but the dogs like it. Have a battery-operated mower and edger/trimmer, plenty good enough for what is needed here. Images are from earlier, in Spring.
