By the middle of July the Illinois Valley holds onto its heat, the bluffs across the water shimmer a little in the afternoon, and lawns need tending on a real schedule to keep up. R & R Landscaping & Irrigation, Inc keeps that schedule around La Salle — mowing, trimming, edging, and the cleanups that bracket the growing season at both ends. A yard cut at a sensible height and edged along the drive looks cool even when the thermometer disagrees. It is a good thing to turn onto a street and see last week's work still holding its shape. La Salle and the neighboring towns of the valley.
