July in Minooka comes in heavy and bright, cicadas going in the parkway trees, sprinklers ticking over lawns that stand where cornfields stood not long ago. Hacienda Landscaping mows through that heat, edging the driveways, trimming close around mailboxes and play sets, and hauling off what the season sheds. A yard cut early, before the pavement turns hot, will hold its color and its shape all week. The subdivisions here are young and their trees are still filling in, which makes a well-kept lawn the thing that gives a street its finish. That is the part worth doing carefully.
