Come October the Waverley Oaks along Beaver Brook let go all at once, and half of Waltham wakes up under a foot of leaves. J.Luna Landscaping service inc. meets that head-on with fall cleanups — leaves pulled off the turf, beds cut back, the lawn given a final low cut before frost. The rest of the year is the steady work: mowing on schedule, edging the drive and walk, trimming the tight ground, mulch put down fresh each spring. Grass under big trees asks for patience, and there is a quiet pleasure in bringing a shaded lawn back thick. The proof is simple enough — you can see the property line from the street again.
