A spring rain moves through this corner of Washtenaw County and leaves everything a shade greener than the day before — and then the mowing year truly begins. Shamrock Home Services LLC works that green from the first flush to the last leaf: mowing, edging, trimming, spring and fall cleanups on Northfield Township properties. The soil holds water in the low spots and dries fast on the rises, so one lawn can need two different touches in a single visit. Done well, the yard looks unbothered — even, tidy, nothing scalped and nothing skipped. Whitmore Lake and the townships around it are where the routes run.
