Hardy Pond sends up mist at first light, and the north-side streets around it wake to the sound of tailgates dropping. Jimenez Landscaping LLC starts the Waltham day right there — mowing, trimming, edges cut in at the drive and walkway, mulch topped off wherever the beds have thinned. Cleanups come twice a year: once to strip out whatever the thaw uncovers, once to clear the leaf fall before it mats down over the grass. Small yards get the same pass as big ones, corner by corner, because corners are where the difference is visible. By the time the neighborhood pours its second cup of coffee, the block looks better than it did.
