July asks a lot of a Pleasantville lawn — long sun, a wind that doesn't cool much past noon, and heat that lingers well after dark. J&M Landscaping and Sprinklers meets it with the basics done right: mowing high enough to shade the roots, trimming clean around beds and posts, edging so the outline of a lawn stays a line and not a suggestion. Cleanups in spring and fall clear the way for everything in between. Yards on the mainland side of the bay sit close together, which means one well-kept lawn lifts the two beside it. That is a decent thing to be responsible for, one week at a time.
